Alta Ski Area conduit micro-hydro project

Alta Ski Area has proposed developing a micro-hydropower project along an existing pipeline, and hopes to benefit from a streamlined regulatory process.  Federal regulators have made a preliminary determination that the proposed Alta Micro-Hydro Project, in Alta, Utah, satisfies the requirements to be treated as a "qualifying conduit hydropower facility," which would not require licensing under the Federal Power Act.

Alta's proposed project would include a new powerhouse to be built along the existing underground 6-inch-diameter snowmaking water supply pipeline delivering water from Cecret Lake to the Wildcat Pump House, a new turbine/generating unit with an installed capacity of 75 kilowatts, intake and discharge pipes, and appurtenant facilities.  The unit is estimated to generate between 115 and 225 megawatt-hours annually.  There is no dam associated with the project.  Alta presented its micro-hydro project as part of a 2012 request to update its master plan, which the U.S. Forest Service accepted.

Ski areas with snowmaking capacity typically have existing pipelines and water infrastructure, coupled with significant vertical relief.  This can create opportunities to generate electricity using energy harvested from water flowing downhill through a pipeline, particularly if reducing system pressure (like a pressure relief valve) is otherwise needed. 

A 2013 law was designed to help small conduit-based hydropower projects by eliminating their need for a license or exemption from licensing issued by the Federal Energy Regulatory Commission.  Section 4 of the Hydropower Regulatory Efficiency Act of 2013 amended Section 30 of the Federal Power Act.  Section 30 now provides that a "qualifying conduit hydropower facility" -- one that is determined or deemed to meet defined criteria -- is not required to be licensed or exempted from licensing under the Federal Power Act.  These criteria include:

• The conduit the facility uses a tunnel, canal, pipeline, aqueduct, flume, ditch, or similar manmade water conveyance that is operated for the distribution of water for agricultural, municipal, or industrial consumption and not primarily for the generation of electricity.
• The facility is constructed, operated, or maintained for the generation of electric power and uses for such generation only the hydroelectric potential of a non-federally owned conduit.
• The facility has an installed capacity that does not exceed 5 megawatts. 
• On or before August 9, 2013, the facility is not licensed, or exempted from the licensing requirements of Part I of the FPA.

The Federal Energy Regulatory Commission administers this statute.  To start the regulatory process, on May 16, 2016, Alta filed a notice of intent to construct a qualifying conduit hydropower facility.  Alta supplemented its notice on May 20 to clarify that the project "will only operate when there is excess capacity available in the pipeline and when water is hydrologically available", generally after the winter snowmaking season, during spring runoff.  Alta also restated that the pipeline's main purpose will continue to be snowmaking.

Yesterday the FERC issued its notice of preliminary determination of a qualifying conduit hydropower facility for Alta's project.  That notice examines the project relative to each of the four statutory criteria, and then provides the Commission's preliminary determination:

The proposed addition of the hydroelectric project along the existing water supply pipeline will not alter its primary consumptive purpose. Therefore, based upon the above criteria, Commission staff preliminarily determines that the proposal satisfies the requirements for a qualifying conduit hydropower facility, which is not required to be licensed or exempted from licensing.

The notice also sets a 30-day deadline for filing motions to intervene, and a 45-day deadline for filing comments contesting whether the facility meets the qualifying criteria and providing an evidentiary basis.

Other recently proposed conduit hydro projects have been determined to be qualifying conduit hydropower facilities, including a Colorado project using an existing "ditch drop," a Castle Valley, Utah water treatment project, a California wholesale water agency conduit project, and a New Hampshire water works.

July 28, 2010 - Alta Wind Energy Center breaks ground; PACE financing

Today's picture: Central Maine Power transmission lines off Route 201 in Topsham, Maine.

In California, the Alta Wind Energy Center — with plans for thousands of acres of turbines to generate electricity for 600,000 Southern California homes — officially broke ground yesterday.  Here's the official project website, which is running a bit slowly today (likely due to all the interest in the project).  Terra-Gen Power, LLC does have a slick website that is worth checking out.  Some highlights include:

• The Alta Wind Energy Center (AWEC), under developed by Terra-Gen Power, is composed of multiple projects.  The first AWEC development is the Alta-Oak Creek Mojave Project.
• The Alta-Oak Creek Mojave Project will be composed of up to 320 wind turbine generators and supporting infrastructure.
• The Project will be developed primarily on privately-owned land adjacent to existing wind energy developments in the Tehachapi area of California.
• The Project is projected to add 50 full-time jobs to the Kern County economy.

 Interest in smart grid deployment is growing.  Federal policy supports smart grid development, and many states are following suit with more specific provisions.  For example, this spring, the Maine Legislature enacted LD 1535 (now P.L. 2009 Ch. 539).  This bill, sponsored by Representative Jon Hinck of Portland, gives Maine a specific smart-grid policy for the first time.  Both CMP and Bangor Hydro, Maine's largest investor-owned utilities are already rolling out smart meters; the legislative policy declaration builds upon this head start.

In enacting the smart grid bill, the Maine Legislature found that:

• The cost of electricity to consumers in this State is high in comparison to costs in similar markets and impedes economic development;
• The State has recognized the consequences of climate change and has committed to policies to reduce emissions of greenhouse gases;
• The State's electric grid and long-term infrastructure investment are vital to continued security and economic development, and smart grid functions will deliver electricity from suppliers to consumers using modern technology to increase reliability and reduce costs in a way that saves energy and to enable greater consumer choice;
• The State currently lacks a comprehensive smart grid policy but faces critical decisions regarding the implementation of smart grid functions and associated infrastructure, technology and applications, and the commission and the Legislature will play central roles in making those decisions; and
• It is vital that a smart grid policy be developed in order to ensure that all ratepayers and the State as a whole are afforded the benefits of smart grid functions and associated infrastructure, technology and applications.

Based on these findings, the Legislature enacted a policy of promoting the development, implementation, availability and use of smart grid functions and associated infrastructure, technology and applications in the State.

With this policy in place, the ball is now in the court of smart grid infrastructure developers.  We now have a law that will support roll-out of smart grid projects in Maine.  Who will be the first to propose one?

How about PACE financing? PACE-promoting provisions got stripped out of the current Senate energy bill. These tweaks are viewed as necessary to let PACE programs flourish, as government-backed lenders Fannie Mae and Freddie Mac have suggested that they won't play with PACE.

July 23, 2010 - no Senate energy bill for now; wind gets boosts

A bit of New Meadows eye candy:


Sure enough, the Senate climate bill is dead. Instead, we'll get a weak energy bill addressing the BP oil spill in the Gulf of Mexico, promoting building energy efficiency through the HomeStar program, and promoting the use of natural gas as a fuel for large trucks.

In Maine, the Fort Halifax dam removal saga continues. Prior to removal of this dam on the Sebasticook River, the town of Winslow, Maine and residents had voiced concerns about erosion, and had appealed (without success) the Department of Environmental Protection's orders approving dam removal. After the dam was removed, portions of the former impoundment's banks suffered severe erosion. The town had to spend over $725,000 to demolish six homes on Dallaire Street that were threatened by the newly eroded banks. The affected areas also included the river bank below the historic (mid-1700s) Fort Hill Cemetery, eroding the bank back much closer to the cemetery fence and grave sites. Former dam owner FPL Energy Maine Hydro commissioned a study of why this erosion happened. FPLE's study concluded that the dam removal and drawdown "did not play a significant role"; instead, the study pointed to unstable soils, steep slopes, heavy rain, and an earthquake. Both the town and the state expressed doubts about this conclusion. Now the town has officially asked the DEP to perform its own study, and to enforce the conditions in its dam removal order that require FPLE to monitor and remediate erosion.

The U.S. Senate Appropriations Committee has approved Susan Collins's request for $10 million in funding for the University of Maine's development, deployment and testing of deepwater and offshore wind turbines. The funding must now be approved by the full Senate, but the parallel House bill still lacks such an appropriation.

Wind is big in California too. It looks like Terra-Gen's Alta Wind Energy Center near Tehachapi is going forward, as it has placed an order with Vestas Wind Systems for 190 3 MW turbines. The Alta Wind project represents the largest financing of a North American wind-energy development to date. Part of the financial picture includes a 1,550 MW power purchase agreement with Southern California Edison for part of the project output. The project will have domestic economic benefits as well: Vestas will manufacture the blades in Windsor, Colorado, and most of the towers in Pueblo, CO.

A growing storm in the Gulf of Mexico has put BP's efforts at the oil well site on hold.
