FERC issues license for Monongahela Locks and Dam 4 project

U.S. hydropower regulators have issued an original license for a proposed 12-megawatt hydropower project, to be located at the U.S. Army Corps of Engineers’ Monongahela Locks and Dam 4 facility on the Monongahela River, in Pennsylvania.

On February 27, 2014, FFP New Hydro, LLC subsidiary Solia 4 Hydroelectric, LLC filed, pursuant to Part I of the Federal Power Act, an application for a license to construct, operate, and maintain the Monongahela Locks and Dam 4 Hydroelectric Project No. 13767.  The company is affiliated with US Renewables Group.

The project would be located at one of the nine existing lock and dam sites on the Monongahela River, which the Army Corps operates for commercial and recreational navigation.  If developed, new facilities for the project would include an intake channel, spill gates, a powerhouse housing two equally sized Kaplan turbine-generator units with a combined capacity of 12 MW, a tailrace channel, a substation, a transmission line, and an access road.  The project will operate in a run-of-release mode, using flows made available by the Corps that would normally be released through the Corps’ spillway gates

Under the Federal Power Act, the Federal Energy Regulatory Commission is charged with regulating and reviewing applications for most non-federal hydropower projects.  Because the project uses the water power or surplus water of a government dam, occupies federal land, and is located on the Monongahela River, which is a navigable waterway of the United States, the Commission concluded that the project is required to be licensed pursuant to section 23(b)(1) of the Federal Power Act.

On July 21, 2017, the Commission issued its Order Issuing Original License for the Monongahela Locks and Dam 4 project.  The license authorizes the installation of 12 MW of new, renewable energy capacity, while requiring a number of measures to protect water quality, fish, wildlife, recreation, and cultural resources at the project.  It bears a 50-year term, the maximum allowable for an original license under Section 6 of the Federal Power Act.

According to the order, as licensed with mandatory conditions and staff-recommended measures, the levelized annual cost of constructing and operating the project will be about $3,563,340, or $72.88/MWh.  Its expected average annual generation will be 48,894 MW. 

The Commission noted that the project as licensed is best adapted to a comprehensive plan for improving or developing the Monongahela River, "because: (1) issuance of an original license will serve to provide a beneficial and dependable source of electric energy; (2) the required environmental measures will protect and enhance fish and wildlife resources, water quality, recreation resources, and historic properties; and (3) the 12 MW of electric capacity will come from a renewable resource that does not contribute to atmospheric pollution."

Report: solar panels add home appraisal value

"How will putting rooftop solar panels on my home affect its value?" is a common question among those considering residential-sited solar energy projects. 

It will help, according to a report recently released by the Lawrence Berkeley National Laboratory, finding solar photovoltaic systems add value to homes in a variety of markets under traditional appraisal methodology as well as statistical analysis.

A residential rooftop solar project in Massachusetts.

Intuition and previous studies have shown a "price premium" effect for solar photovoltaic systems in some markets.  Where a price premium applies, a home with a solar PV system can command a higher price than a comparable home without one.

A 2013 study of California using statistical analysis found "clear support that a premium exists in the marketplace; thus, PV systems have value, and their contribution to home values must be assessed."  That study found a strong correlation between premiums and PV system size, and a weak negative correlation with PV system age.  Essentially, "larger systems garner larger premiums and older systems garner smaller premiums," with each 1-kilowatt increase in size estimated as commanding a $5,911 higher premium, while each year of system age yields a $2,411 lower premium.  

A similar 2014 study of eight states found "PV consistently adds value across a variety of states, housing and PV markets, and home types."  Notably, these studies relied heavily on hedonic or regression pricing models to account for characteristics specific to each property (home type, site, neighborhood, market).  While such large-scale statistical analysis is commonly performed in economics, home buying more commonly relies on the appraisal process to support both price formation and financing.  Few previous studies were written by experienced real estate appraisers using paired-sales techniques or other standard appraisal methods.

The Lawrence Berkeley National Laboratory has released a report designed to bridge this gap, featuring a comparison of statistically derived PV premiums and analysis performed by experienced home appraisers.  That report, "Appraising into the Sun: Six-State Solar Home Paired-Sales Analysis", examined 43 pairs of comparable homes that sold with and without PV across seven areas in six state (California, Oregon, Florida, Maryland, North Carolina, and Pennsylvania).  It compared traditional real estate appraisal analysis of these homes to contributory-value estimates based on gross cost, net cost, and income. Overall, it found that under either statistical or appraisal based analysis, PV systems added premiums of $2.68/W to $4.31/W across states, averaging $3.78/W or about $14,000 for an "average-size" system sold in 2011 (3.8 kW).

The study did identify some difficulty in conducting comparable-sales analysis on homes with solar panels.  (It also includes a section titled "Warning to Users of this Study", noting the analysis was limited to specific times and places, only considered host-owned systems with crystalline-silicon panels, and does not address potential sales price implications related to the location of the PV systems.)  However, it found that appraised premiums are in agreement with the hedonic modeling results as well.  Practically speaking, this means cost- and income-based statistical estimates of PV premiums could be reliable when paired-sales analysis is impossible.

Further information about the Lawrence Berkeley National Laboratory report on appraisal value of residential solar PV systems can be found in a November 12, 2015 presentation hosted on its website.

Constitution Pipeline environmental impact statement

A 124-mile natural gas transmission pipeline proposed from Pennsylvania to New York has received its final environmental impact statement from federal regulators, finding that while the project would cause some adverse environmental impacts but that mitigation would reduce them to less-than-significant levels.

The proposed Constitution Pipeline is designed connect natural gas supplies in northern Pennsylvania with major northeastern markets.  Proposed by Constitution Pipeline Company, LLC, a group whose investors include Williams, Cabot Oil & Gas, Piedmont Natural Gas, and WGL Holdings, the 30-inch underground pipeline would have a design capacity of 650,000 dekatherms of natural gas per day.  Constitution has pitched the project as a response to natural gas market demands in the New York and the New England areas, and interest from natural gas shippers that require transportation capacity from Susquehanna County, Pennsylvania to the existing Tennessee Gas Pipeline Company LLC (TGP) and Iroquois systems in Schoharie County, New York.

Developing an interstate natural gas pipeline requires a series of federal, state, and local approvals.  Under the federal Natural Gas Act, interstate pipelines must obtain a Certificate of Public Convenience and Necessity from the Federal Energy Regulatory Commission prior to construction.  Constitution started the pre-filing process in April 2012, and filed its certificate application under Section 7(c) of the Natural Gas Act with the FERC on June 13, 2013.

Under the National Environmental Policy Act, federal agencies must analyze and document the environmental effects of proposed federal actions such as issuing a certificate of public convenience and necessity for an interstate pipeline.  For the Constitution Pipeline and its associated Wright Interconnect compressor transfer station, FERC staff evaluated the projects' impacts on natural resources including geology, soils, groundwater, surface water, wetlands, vegetation, wildlife, fisheries, special status species, land use, visual resources, socioeconomics, cultural resources, air quality, noise, and safety.  Staff considered the projects' cumulative impacts along with other past, present, and reasonably foreseeable actions in the projects’ area.  Staff also evaluated over 400 alternatives to the projects, including the "no-action" alternative, system alternatives, major and minor route alternatives, and minor route variations.  In a collaborative effort, FERC staff also collected input from cooperating agencies including the U.S. Environmental Protection Agency, the U.S. Army Corps of Engineers, the Federal Highway Administration, and the New York State Department of Agriculture and Markets. 

FERC staff issued their Final Environmental Impact Statement, or EIS, for the Constitution Pipeline and Wright Interconnect projects on October 24, 2014.  In that document, staff concluded that construction and operation of the Constitution Pipeline and the associated Wright Interconnect would result in some adverse environmental impacts, but these impacts would be reduced to less-than-significant levels with the implementation of mitigation measures proposed by the company and additional measures proposed by FERC.  These mitigation measures include implementing plans for upland erosion control, revegetation, and maintenance plan, protecting wetlands and waterbodies, spill plans for oil and hazardous materials, an organic farm protection plan, and a karst mitigation plan. FERC staff also proposed an environmental inspection and mitigation monitoring program to ensure compliance with all mitigation measures that become conditions of the FERC authorizations and other approvals.

For the Constitution Pipeline project, the EIS represents a relatively favorable recommendation by FERC staff to the Commissioners.  The ultimate decision whether FERC will issue the project a certificate rests solely with the Commissioners themselves, but regulators typically rely heavily on their technical staff's evaluation of environmental impacts.  Likewise, while FERC's final EIS is not necessarily binding on cooperating agencies, they may adopt it if it satisfies their own statutory mandates for environmental reviews.

While the applicants had initially proposed to start construction in 2014, FERC staff acknowledged that "the proposed dates for the start of construction are no longer feasible."  Constitution now proposes to start construction in February of 2015 and continue through the end of 2015, pending receipt of all applicable federal authorizations.  The Federal Energy Regulatory Commission may rule on the projects' certificate applications as early as late November this year.

FERC authorizes mine drainage microhydro

The Federal Energy Regulatory Commission has issued a hydropower license to a project whose turbines generate electricity from acid mine drainage. The micro-hydropower license issued to the Antrim Treatment Trust illustrates this unusual approach to the twin challenges of mine remediation and renewable energy.

The power of falling water, in the White Mountain National Forest in New Hampshire.

In the 1980s, Antrim Mining, Inc. operated a surface bituminous coal mine in Pennsylvania.  When water draining through the mine and into streams and rivers was found to exceed pollution limits, the Commonwealth of Pennsylvania charged the company with violations of mining and reclamation law.  The charges led to a series of settlements through which Antrim agreed to improved water treatment facilities, including an off-the-grid hydroelectric facility.  This micro-hydro plant would be powered by treated effluent flowing downhill out of lagoons.  Antrim created the Antrim Treatment Trust to manage treatment of the mine water in 1991, then went out of business.

In an attempt to reduce the cost of treating the site's severe acid mine drainage, the Babb Creek Watershed Association identified micro-hydropower as an option for the site.  In 2008, the association received an Energy Harvest Grant from the Pennsylvania Department of Environmental Protection.  This $428,710 award was designed to support the installation of two hydroelectric turbines on the treatment plant's discharge, which was completed in 2012.

While the Federal Power Act requires most hydropower projects to secure a license from the Federal Energy Regulatory Commission, some off-grid hydropower projects that do not use the waters of the United States do not require licensure.  In 2010, the Antrim Treatment Trust filed a Declaration of
Intent for a 40-kilowatt grid-connected project, but quickly revised its project to be off-grid after the Commission issued an order finding that a license was required for the grid-connected project.  Once the project was off-grid, the Commission ruled that no license was required.

The Antrim treatment plant seems to have then operated one turbine, but left the second turbine non-operational. A 2012 article in the Williamsport Sun-Gazette suggested that with both turbines running and selling power into the electricity grid, the treatment plant could cut $12,000 in annual power costs and make $10,000 per year in new revenue.  But this could require a FERC license, because the project would become connected to the utility grid.

The Trust appears to have decided that these economics were worth pursuing, because in 2013 it filed an application for a project license for a 40-kilowatt project.  In the application, Antrim Trust proposed to bring a second identical turbine (currently in place but non-operational) online by installing additional indoor wiring with appurtenances within the existing powerhouse and treatment plant, and operate both turbines as a grid-connected project using the treated and/or untreated water.

As licensed, the Commission estimates the annual cost to develop and maintain the proposed 40-kW project is $9,356 or $37.42/megawatt-hour (MWh).  The project will generate an estimated average of 250 MWh of energy annually.  Based on Commission staff’s view of the alternative cost of power ($56.93/MWh), the total value of the project’s power is $14,233 in 2013 dollars.  To determine whether the proposed project is currently economically beneficial, staff subtracts the project’s cost from the value of the project’s power. Therefore, in the first year of operation, the project is expected to cost $4,877 or $19.51/MWh less than the likely alternative cost of power - demonstrating economic benefit.

Micro-hydropower projects can make economic sense in some mine drainage situations and other places where water treatment is required and a suitable vertical drop or pressure is available.  In Antrim's case, the project's success can partially be explained by the existence and purpose of the Trust, as well as the DEP grant to support project construction.  If treated and untreated mine drainage can be used to generate hydroelectricity, what other unusual sources of power will arise?

Assessing Hurricane Sandy's energy impacts

Yesterday Hurricane Sandy made landfall in New Jersey, but the magnitude of the storm meant that heavy winds, strong rains, and a powerful coastal storm surge affected a broad swath of the mid-Atlantic and northeastern parts of the United States.

One consequence of the storm is widespread power outages.  As of 8:00 AM yesterday, about 36,000 electricity customers had lost power in Connecticut, Delaware, New Jersey, New York, North Carolina, Rhode Island, and Virginia.  By 2:00 PM yesterday, outages were up to over 316,000, in the states listed above as well as in Maryland, Massachusetts, New Hampshire, and Pennsylvania.  At that time, New York had the most outages (105,089 customers, or about 1%), but New Hampshire was the hardest hit in terms of percentage affected (18,190 customers, or about 3%).  These reported outages came six hours before the storm officially made landfall, making outage numbers much higher today -- some reports indicating 8 million customers without power.

[Update: as of 9:00 AM this morning, the Department of Energy reports 8.1 million customers without electricity, including 62% of New Jersey, 31% of Connecticut, and 23% of Rhode Island.]

In addition to these power outages, some electricity generating facilities have shut down.  The U.S. Nuclear Regulatory Commission (NRC) reports three nuclear power units in the Northeastern United States had to shut down and two units reduced as a result of impacts from Hurricane Sandy.  Reasons range from water pump failure to encroaching high water to problems on the external power grid.

Another consequence of the storm is disruption to oil refineries.  By 1:00 PM yesterday, two mid-Atlantic refineries had closed, with four more shutting down part of their production.  In total, 1.1 million barrels per day of refining capacity had been disrupted due to the storm.

Today, as the storm has moved inland, crews are working hard to recover from the storm.  It is still early to assess the total damage from the storm, as well as whether its disruption to energy infrastructure will be temporary or longer-lasting.

Hurricane Sandy's effects on energy

Hurricane Sandy is expected to make landfall near the southern coast of New Jersey this evening.  The storm has already dealt damage to Cuba, Jamaica, and Haiti, and is expected to carry significant storm energy northward into the mid-Atlantic and northeastern United States.  Power outages are already being reported, but many more are expected: according to a Johns Hopkins engineering model, up to 10 million people may lose electricity in the mid-Atlantic over the next week.  Utilities are already staffing up and hiring external contractors to assist in the storm recovery efforts.  State governors are declaring a state of emergency to waive limits on how many hours utility workers can drive and work, to allow workers from other states and Canadian provinces to assist.

Hurricane Sandy's effects on energy are not limited to electric infrastructure.  Petroleum refineries - and by extension oil and gas markets - will also be impacted by the storm. According to a situation report released this morning by the U.S. Department of Energy's Office of Electricity Delivery & Energy Reliability, at least one petroleum refinery has already shut down.  Phillips 66's Linden, NJ refinery has shut down its production; the Linden refinery is capable of producing 238,000 barrels per day.

The report also cites trade press reports indicating reduced production at two other mid-Atlantic oil refineries, Philadelphia Energy Solutions’ Philadelphia, PA refinery (335,000 b/d capacity) and PBF Energy’s Delaware City refinery (182,200 b/d capacity).  Hurricane Sandy's impacts to refineries are not limited to those processing crude oil; the report also cites reduced production rates at Hess Corporation’s Port Reading, NJ facility (70,000 b/d capacity), which processes gas oils to produce petroleum products.

Collectively, these refineries do not account for a significant portion of the nation's refining capacity.  However, the impacted facilities' concentration in the mid-Atlantic may temporarily raise gasoline prices in the mid-Atlantic and northeastern U.S.  A key factor affecting the extent of this price bump will be how quickly the refineries can return to full production.

When tomorrow morning comes, the storm's direct impacts will be well underway, as will restoration efforts.  Last year's October storm, Hurricane Irene, left many electric utility customers without power for over a week.  How will Sandy compare to Irene?

National Park Service OKs transmission line on park lands

The National Park Service has given its final approval to a proposed high-voltage electric transmission line that would cross public lands in Pennsylvania and New Jersey, including the Delaware Water Gap National Recreation Area, the Middle Delaware National Scenic and Recreational River as well as the Appalachian National Scenic Trail.

The 500 kilovolt transmission line, known as the Susquehanna-Roseland line, has been proposed by utilities PPL Electric Utilities and Public Service Electric and Gas Co. It would run 145 miles from Susquehanna, Pennsylvania to Roseland, New Jersey.  Mid-Atlantic electric grid operator PJM, Inc. and national electric reliability organization NERC had called for the line to protect the grid's reliability by preventing existing power lines from facing overloaded conditions.  The line also received a fast-track review by federal agencies under the auspices of the Interagency Rapid Response Team for Transmission, a group formed to coordinate on an expedited review of transmission projects designed to increase grid reliability, integrate new renewable energy, and cut consumer costs.

While the line's route largely followed existing rights-of-way, environmentalists and park activists challenged the National Park Service's approval of expansions to the rights-of-way through these national parklands.  The New Jersey Board of Public Utilities' approval of the project was also challenged, on the grounds that the state board failed to give adequate consideration to non-transmission alternatives that could have met consumer demand, such as programs promoting demand response and energy efficiency.  That case remains pending.

On Monday, the National Park Service issued its record of decision approving the line (31-page PDF).  As a condition of approval, the NPS required the developing utilities to contribute at least $56 million to a
fund to mitigate the line's impacts on federal lands by purchasing or otherwise conserving land for public use, compensating for impacts to wetlands affected by the line, and funding cultural and historic preservation in the affected parks.

In a Facebook post issued yesterday, the New Jersey chapter of the Sierra Club vowed to challenge the NPS's approval of the line in court.  PPL and PSE&G plan to place the line in service by June 2015.

Marcellus shale gas drilling slows

Natural gas drilling activity has declined in parts of the Marcellus Shale formation under Pennsylvania and other eastern states, largely as a result of low gas prices.  These prices in turn are largely the result of significant increases in the available supply of recoverable natural gas made possible by horizontal drilling techniques and hydraulic fracturing or fracking.  As a consequence, many natural gas producers are focusing on areas of shale rich in both gas and natural gas liquids.

The Marcellus Shale, a layer of ancient marine sediment rich in organic material and extending beneath Pennsylvania, Ohio, West Virginia, New York, and Maryland, is believed to be one of the world's largest natural gas fields.  In 2008, drilling activity in the Marcellus Shale began to increase significantly, as these newer drilling techniques and increases in the price of other fuels like oil made the shale gas economically feasible to recover.  (Compare this map of Marcellus shale drilling activity in Pennsylvania from 7/25/2008 to this map of permits issued as of March 9, 2012.)  As of this spring, Pennsylvania alone had issued 11,772 permits for vertical and horizontal gas wells in the Marcellus formation.

One result of the expansion of shale gas production is a significant decrease in the price of natural gas.  Since 2008, natural gas prices at the Henry Hub in Louisiana (where gas as a commodity is typically priced) have fallen from over $12 per million British thermal units (MMBtu) to as low as $2 per MMBtu.  Other factors have played a role in this price decline, such as a mild winter with lower-than-expected heating demand and the overall economic slowdown, but the increase in supply due to shale gas production is viewed as a major cause of the price decline.

Now, one of the effects of the price decline is a decrease in natural gas drilling activity.  This decrease is particularly marked in areas where the shale produces "dry gas", or natural gas that is primarily methane and is low in so-called natural gas liquids.  Natural gas liquids -- hydrocarbons other than methane that are extracted when natural gas is processed in a natural gas treatment facility -- include ethane, propane, and butanes.  These natural gas liquids are important feedstocks for the production of many chemicals and plastics, and add value to the natural gas produced from "wet" shales.

Where shale gas contains significant amounts of natural gas liquids, production appears steady or increasing, while gas producers in areas with lower amounts of natural gas liquids are now saying that they are having a hard time making money off gas alone.  If this trend continues, areas of dry gas like much of the known portions of the Marcellus Shale may continue to see a slowdown in drilling activity while producers focus on areas rich in natural gas liquids.

Pro football goes green?

This year the National Football League's Philadelphia Eagles plan to install renewable electricity generation at the Eagle's home stadium.

Under the deal announced earlier this spring, energy and utility giant NRG will install 11,000 solar panels and 14 small-scale wind turbines at Lincoln Financial Field in Philadelphia.  NRG reportedly plans to install solar panels along the south and west sides of the stadium as well as in parking lot space, with wind turbines lining the stadium's north and south sides.  Construction is supposed to be complete by the end of 2012.

Sporting facilities like pro football fields typically consume most of their electricity during the relatively few days of the year when they are used, so these renewable electric generation assets may never fully power the Eagles' field during a home game.  At these times, the stadium will most likely continue to draw power from the utility electric grid.  For this reason, it may be no coincidence that the deal also calls for NRG to become the official supplier of grid power to the stadium.

On the flip side, the solar and wind generation will likely produce most of its power when the stadium demands relatively little power, making Lincoln Financial Field a potential candidate for a net metering program such as Pennsylvania has enacted.  Over an entire year, reports suggest that the solar and wind assets proposed for Lincoln Financial Field will produce about six times the power used during all Eagles home games.

The NRG deal is not the first proposal to develop clean energy facilities at the Eagles' stadium.  In 2010, the Eagles announced a similar partnership with Solar Blue, which would have included a natural gas-fired cogeneration power plant in addition to solar and wind generation.  That project was ultimately scrapped.

Nevertheless, if the NRG project happens, the Eagles will join a growing trend of professional sports teams seeking to green their image, improve their sustainability, and cut their energy costs. 

NJ-PA transmission line challenged

A New Jersey court is considering a challenge by environmental activists to a proposed high-voltage transmission line connecting Pennsylvania and New Jersey.

Proposed by PPL Electric Utilities and Public Service Electric and Gas Co., the Susquehanna-Roseland line would run 145 miles from PPL's Susquehanna substation near Berwick, Pennsylvania to Roseland, New Jersey.  The route, which is nearly finalized, would cross three units of land managed by the National Park Service: the Delaware Water Gap National Recreation Area, the Middle Delaware National Scenic and Recreational River and National Recreation Water Trail, and the Appalachian National Scenic Trail. 

The Susquehanna-Roseland project has received the approval of the New Jersey Board of Public Utilities, as well as federal support in the form of an expedited permitting process.  Regional grid operator PJM Interconnection, LLC has also said that the line is essential to improving reliability and reducing transmission line congestion in the region.

At the same time, the line has drawn opposition from environmental groups and others.  The Sierra Club and other organizations have challenged the line as continuing a "reliance on toxic fossil fuels by shipping coal-fired power into New Jersey." Instead, the Sierra Club calls for increased use of demand response, energy efficiency and renewable energy to meet peak energy demands.  Other have challenged the project's proposed route through National Park Service lands, including widening some existing transmission corridors and associated road-building activity.

This past Wednesday, the Appellate Division of the Superior Court of New Jersey heard oral argument over whether the New Jersey Board of Public Utilities' approval of the project was valid.  Among the challenges raised was whether the BPU fully considered non-transmission alternatives to the line, such as demand response and energy efficiency.

While the court process concludes, the utility proponents believe that construction should not be affected by the lawsuits.  The line is expected to be placed in service by summer 2015.

Transmission lines on national park land provoke challenge

A 145-mile high voltage transmission line upgrade connecting Pennsylvania and New Jersey is on a fast-track review process at the federal level, but a proposed route through the popular and scenic Delaware Water Gap National Recreation Area and other lands managed by the National Park Service is drawing opposition.

Last fall, nine federal agencies formed the Interagency Rapid Response Team for Transmission.  This group announced a coordinated federal policy decision to expedite the review process for 7 electric transmission lines across 12 states.  These pilot projects were selected based on the premise that, when built, they will help increase electric reliability, integrate new renewable energy into the grid, and save consumers money.

Of these fast-tracked projects, the one farthest along in development is a 500-kilovolt line proposed by PPL Electric Utilities and Public Service Electric and Gas Co. 's running from PPL's Susquehanna substation near Berwick, Pennsylvania to Roseland, New Jersey.  While the exact route of the line is not yet final, the utilities have requested a construction and right-of-way permit from the National Park Service for the expansion of an existing electric transmission line that crosses NPS lands within Pennsylvania and New Jersey.  Three units of National Park Service lands would be affected by the project: the Delaware Water Gap National Recreation Area; the Middle Delaware National Scenic and Recreational River and National Recreation Water Trail; and the Appalachian National Scenic Trail.

Environmental and conservation activists have challenged any plan to route the line through national park lands.  The utilities propose to expand upon an existing right-of-way across these units which contains a single 230kV electric transmission line.  Existing towers would be replaced by new, taller tower structures.  The 230 kV line would be upgraded to carry 500 kV, and an additional 500 kV line would be added.  This work would also entail widening the existing right-of-way and constructing new access roads.  The utilities have offered a mitigation package that includes the conservation of thousands of acres of high-priority lands.  In addition, proponents say the line would save consumers more than $200 million each year in electric bills and create 2,000 jobs through construction.

The Park Service has released its draft environmental impact statement analyzing the project's impacts, and a final route is expected to be selected in March 2012. 

Susquehanna River flooding threatens dam, communities

Close on Hurricane Irene’s heels, the remnants of Tropical Storm Lee are dropping up to 10 inches of rain across the northeastern United States.  As we saw when Irene hit Vermont, storms like this can cause not only widespread flooding as streams rise above their banks, but even risk dam failure and more catastrophic flooding.

Now, the rains caused by Tropical Storm Lee have led authorities from Maryland to New York to order the evacuation of nearly 100,000 people.

Flooding along the Susquehanna River is responsible for a large portion of this risk.  Arising out of branches in upstate New York and western Pennsylvania, the 464-mile long Susquehanna is the longest river on the east coast to drain into the Atlantic Ocean.  The river overtopped retaining walls in Binghamton, NY earlier today, leading to road closures that effectively isolate the city.  Downstream, deepening floods have caused the evacuation of the entire city of Wilkes-Barre, PA.

The Susquehanna flooding has also impacted the Conowingo hydroelectric dam about 10 miles above the river’s mouth in Maryland.  With 11 turbines providing a nameplate capacity of 572 megawatts, the Conowingo dam is one of the nation's largest non-federal hydroelectric facilities.  Now operated by Exelon subsidiary Susquehanna Electric Company, the Conowingo Dam is threatened by the Susquehanna floodwaters.  As a result, 50 of the dam’s 53 flood control gates have been opened, causing authorities to evacuate people from the downstream communities of Havre de Grace and Port Deposit.  Area residents remember 1972's Hurricane Agnes, whose rains and flooding caused all 53 flood gates to be opened and the dam operator to prepare for a controlled breach of part of the dam.

As Lee’s rains move out of the area, water levels in the Susquehanna River will peak and then recede.  Time will tell how damaging the flood waters will be.

Remember the huge underground coal mine fire that destroyed the town of Centralia, Pennsylvania? It's back in the news today. The state is moving to take the property within the town by eminent domain, apparently so it can sell the mineral (coal) rights to a mining company. Meanwhile, the few remaining residents are claiming fraud, namely that the underground fire isn't so dangerous and that their property should remain theirs.

The Obama administration approved $1.37 billion in federal loan guarantees to help build the world's largest solar power complex in California. The Department of Energy has offered to backstop the loans of BrightSource Energy, the developer of three proposed solar-energy plants in the Mojave desert. If completed, the three BrightSource projects could power 140,000 homes, and nearly double the amount of solar power generated in the United States. Despite a recent scale-back to address environmental concerns, the Ivanpah Valley project is still budgeted at 392 MW. BrightSource estimates that construction will employ about 1,000 people, with operation creating 86 permanent jobs. Bechtel, the engineering and construction contractor for the project, signed a project labor agreement in December 2009 with the State Building and Construction Trades Council of California (SBCTC) and the Building & Construction Trades Council of San Bernardino and Riverside counties to secure benefits to the local workforce from the project. The project is estimated to provide $400 million in tax revenues to state and local government, and produce $650 million in wages, over the next 30 years. The project will come online in 2012 and 2013.

Worth noting: US Secretary of Energy Chu's Facebook page, focused at the moment on "why we need nuclear".

More fallout and analysis of Google's approval for market-based rate authority (MBRA) from FERC. Donald Campbell of Pitt News suggests that Google secured MBRA so it could more effectively buy green power: "Combined with some offshoot ventures previously spawned by Google, energy trading can assist Google in increasing the amount of energy it consumes from renewable sources." Other sources note that Google doesn’t intend to resell energy, but to procure power only for its own use to help it manage energy costs as a whole. Interestingly this 2/22 interview with Google's "green energy czar" Bill Weihl doesn't mention MBRA as a strategy.
