Navy signs solar energy deal

The U.S. Department of the Navy has announced an agreement for the development of a 210 megawatt (DC) solar project to supply electricity to Navy and Marine Corps facilities in California.  The Navy described the deal as the largest purchase of renewable energy by a federal entity to date.

Solar photovoltaic panels in Utah - much smaller project than the Navy project.

The Navy has expressed interest in renewable and alternative energy for some time, buying biofuels and renewable electricity.  According to the website for Deputy Assistant Secretary of the Navy - Energy, Joseph Bryan:

The Navy's energy strategy takes the "long view" necessary to keep our Navy and our nation strong. Bottom line: incorporating energy initiatives now will allow us to more effectively carry out our mission in the future.

In 2009, Congress mandated that 25 percent of the energy used in Department of Defense facilities come from renewable sources by 2025.  Secretary of the Navy Ray Mabus then set an accelerated goal for his branch of the military: 1 gigawatt of renewable energy procurement by the end of 2015.  In the Navy's view, resources like solar power can help diversify its shore energy portfolio and provide long-term cost stability, which ultimately contributes to the Navy's overall energy security priorities.

In furtherance of this goal, last year the Western Area Power Administration issued a request for proposals for renewable energy projects to supply power to Navy facilities in California.  Through a competitive process, Sempra U.S. Gas & Power LLC was selected to develop the Mesquite 3 Solar project.  Sempra is a subsidiary of San Diego-based Sempra Energy, a major energy services holding company. It has developed a variety of solar and wind energy generation projects, including the existing Mesquite 1 Solar project about 60 miles west of Phoenix, Arizona.

The Navy announced that it had signed the agreement on August 20, at a ceremony co-hosted by Western Area Power Administration and Sempra.  Under the Navy deal, Sempra will develop the Mesquite 3 project as an expansion of the existing Mesquite site.  Mesquite 3 will feature over 650,000 photovoltaic panels on ground-mounted, horizontal single-axis trackers.  Construction is scheduled to begin in August, with completion expected by the end of 2016.  While pricing terms have not been disclosed, the Navy reports that it will save at least $90 million over the life of the project.

Will other units of federal government follow the Navy's model in contracting for renewable energy in this manner?  How will solar project business structures change if federal entities start playing a larger role as buyers?

Feds settle on final 2011 Southwest blackout penalty

Over four years after a major 2011 power outage in Southern California and parts of the Southwest, federal energy regulators have approved the sixth and final settlement of penalties for violations of law and reliability standards. 

After the September 8, 2011 blackout left more than 5 million people in Southern California, Arizona and Baja California, Mexico, without power for up to 12 hours, the Federal Energy Regulatory Commission began investigating what had happened.  After conducting that investigation jointly with electric reliability organization North American Electric Reliability Corporation (NERC), in an April 2012 report FERC found that the outage started when a 500-kilovolt transmission line owned by utility Arizona Public Service Company tripped.

The FERC continued its investigation into the 2011 Southwest blackout after its staff report was made public.  It identified six entities believed to have been involved: Arizona Public Service Company, the California Independent System Operator, the Imperial Irrigation District, Southern California Edison, the Western Area Power Administration, and the Western Electricity Coordinating Council Reliability Coordinator.

FERC's enforcement process typically offers the accused an opportunity to agree to a stipulation of facts (for example, that the utility violated a particular reliability standard) and to pay a civil penalty and perform mitigation measures.  In its enforcement actions related to the 2011 Southwest blackout case, all six entities ultimately agreed to stipulations and penalties that were accepted by the Commission.

In July 2014, the FERC accepted Arizona Public Service's stipulation with NERC and FERC's Office of Enforcement, under which APS agreed to pay $3.25 million and improve its system reliability.  In August 2014, California's Imperial Irrigation District agreed to a $12 million fine.  Utility Southern California Edison agreed to a $650,000 fine in October.  In December, FERC settled with federal power marketing agency Western Area Power Administration with no penalty.  Grid operator California ISO agreed to pay $6 million.

This week the FERC announced a settlement with Western Electricity Coordinating Council.  WECC promotes grid reliability in the Western Interconnection, a broad area of the western United States.  According to the FERC order, FERC enforcement staff and NERC determined that WECC as the Reliability Coordinator violated nine requirements of the Interconnection Reliability Operations and Coordination (IRO) and the Facilities Design, Connection and Maintenance (FAC) groups of Reliability Standards.  Enforcement staff and NERC concluded that WECC failed to identify and prevent violations of system operating limits and Interconnection Reliability Operating Limits and was unaware of the impact of protection systems, and used an inadequate system operating limit methodology that exposed its area to cascading outages.

As a result, the settlement calls for WECC to pay a $16 million civil penalty.  $3 million of this will be split evenly between the U.S. Treasury and NERC, and $13 million will be invested in reliability enhancement measures that go above and beyond mitigation of the violations and the requirements of the Reliability Standards.  WECC and its successor as Reliability Coordinator, Peak Reliability, also agreed to mitigation and reliability activities and to submit to compliance monitoring.

FERC has described the WECC settlement as marking "final resolution" of the investigation by FERC Enforcement staff and NERC into the 2011 Southwest blackout.

4th California blackout FERC enforcement case settles

Federal regulators have approved a settlement with another federal agency over its role in a 2011 blackout in California, Arizona, and Mexico.

On September 8, 2011, the Southwest's electric grid was hit with a widespread power outage that left over 5 million people in California, Arizona and Baja California, Mexico, without power for up to 12 hours.  Previous investigations by the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Corporation (NERC) found that the blackout occurred when Arizona Public Service Company's 500-kilovolt Hassayampa-N.Gila transmission line tripped out of service, overloading the remaining elements of the regional grid. 

Earlier this year, FERC approved stipulations and consent agreements among its Office of Enforcement, NERC, and three public utilities.  Arizona Public Service agreed to pay $3.25 million in civil penalties, California's Imperial Irrigation District agreed to a $12 million settlement, and  Southern California Edison Company agreed to pay a $650,000 civil penalty and undertake additional compliance actions.

FERC approved a fourth settlement on November 24, 2014, with the Western Area Power Administration – Desert Southwest Region (Western-DSW).  One of four power marketing administrations within the United States Department of Energy, the Western Area Power Administration (WAPA) markets and transmits electricity to a fifteen-state region from hydroelectric power facilities at the Hoover, Parker, and Davis dams. Western-DSW is one of four regions carrying out this mission for WAPA, serving customers in Arizona, Southern California, and Southern Nevada. It sells more than ten billion kilowatt hours of hydroelectric power to approximately seventy municipalities, cooperatives, federal and state agencies, and irrigation districts. Western-DSW also operates and maintains more than forty substations and 3,100 miles of transmission lines.

In the FERC Order Approving Stipulation and Consent Agreement, the Commission notes that Western-DSW violated four Requirements of three Reliability Standards in the Transmission Operations (TOP) and Voltage and Reactive Control (VAR) categories. These groups of standards cover the responsibilities and decision making authority for reliable operations and maintenance of Bulk Power system facilities within voltage and reactive power limits to protect equipment and ensure reliable operation of the interconnection.  In particular, FERC Enforcement staff and NERC found that Western-DSW failed to operate its portion of the transmission system within voltage system operating limits and to maintain sufficient situational awareness prior to and during the event, undermining reliable operation of the Bulk Power System.

Western-DSW stipulated to the facts in the agreement and agreed to implement compliance measures necessary to mitigate the violations and improve overall reliability, including improving its models, better coordination with neighboring entities, and improving its situational awareness by adding a real-time monitoring tool that analyzes and alerts operators to potential contingencies. Western-DSW also agreed to make semi-annual compliance reports to Enforcement staff and NERC for at least one year.  Notably, the stipulation does not require Western-DSW to pay a civil penalty.

FERC's general investigative report on the incident identified six potential targets for enforcement action.  With cases settled against Western-DSW, SoCal Edison, the Imperial Irrigation District, and Arizona Public Service, only the California Independent System Operator and the Western Electricity Coordinating Council Reliability Coordinator have not yet been parties to a stipulation and consent agreement.

Southwest Power Pool to expand

The Federal Energy Regulatory Commission has largely accepted a proposal to expand the geographic footprint of the Southwest Power Pool, a regional power market that will soon include a significant portion of the Upper Great Plains.

Southwest Power Pool, Inc. (SPP) was founded in 1941 by a coalition of regional power companies interested in keeping an Arkansas aluminum factory supplied with power to meet critical defense needs.  Since 2004, SPP has been recognized by the FERC as a Regional Transmission Organization or RTO.  Today, SPP organizes and operates parts of the electric power grid in nine states: Arkansas, Kansas, Louisiana, Mississippi, Missouri, Nebraska, New Mexico, Oklahoma, and Texas. 

On September 11, 2014, pursuant to section 205 of the Federal Power Act (FPA), SPP submitted to the FERC proposed revisions to its governing documents to facilitate the decision of three major transmission owners of the so-called Integrated System in the Upper Great Plains to join SPP.  The three proposed member-owners are:

• Western Area Power Administration – Upper Great Plains Region: one of four regions of the United States Department of Energy's Western Area Power Administration. Western is a federal power marketing agency that markets federal power and owns and operates transmission facilities through 15 western and central states, encompassing a geographic area of 1.3 million square miles. Western ’s primary mission is to market federal power and transmission resources constructed with Congressional authorization. The federal generation marketed by Western is generated by power plants that were constructed by federal generating agencies, principally the Department of the Interior’s Bureau of Reclamation and the U.S. Army Corps of Engineers. In the Upper Great Plains Region , or Western - UGP, Western owns an extensive system of high - voltage transmission facilities and markets federally generated hydroelectric power in the Pick - Sloan Missouri - Basin Program - Eastern Division of Western.
• Basin Electric Power Cooperative: serves 2.8 million customers in territories covering approximately 540,000 square miles using nearly 2,100 miles of transmission lines and 70 switch yards
• Heartland Consumers Power District: a public corporation and political subdivision of the State of South Dakota. It provides wholesale power to 28 municipalities in eastern South Dakota, southwest Minnesota, and northwest Iowa, to six South Dakota state agencies, and to one electric cooperative in South Dakota.

These entities proposed to join SPP as transmission owning members, to place their respective transmission facilities under the functional control of SPP, and to begin taking transmission service under the SPP Tariff.  Their stated motivation was increasing market size and thus opportunities for both consumers and producers of energy.

By order dated November 10, 2014, the FERC accepted SPP's proposal.  Together, these new SPP members provide the backbone of the bulk electric transmission system across seven states in the Upper Great Plains region consisting of approximately 9,500 miles of transmission lines rated 115 kV through 345 kV.  The FERC order directed SPP to take certain interim steps, and SPP has announced plans to integrate the three new utilities by October 2015.
