NH conduit hydropower project approved

Federal regulators have determined that a proposed hydropower facility at a New Hampshire wastewater treatment plant can be built without a license, under a recently enacted law.  The Federal Energy Regulatory Commission staff has found that the Ammonoosuc Water Treatment Plant Hydroelectric Project proposed by the City of Berlin Water Works is a qualifying conduit hydropower facility under federal law.  Like other conduit projects, the Ammonoosuc project involves the addition of a turbine into an existing system of pipes and pressure reduction valves, and can create additional renewable energy with few incremental impacts.

Under the Federal Power Act, most hydropower projects in the U.S. require licensure by the Federal Energy Regulatory Commission.  But last year, Congress passed the Hydropower Regulatory Efficiency Act of 2013, easing the regulatory burden on projects.  That law exempts certain so-called "conduit" hydropower facilities from the licensing requirements of the Federal Power Act.  Conduit facilities generate electricity using only the hydroelectric potential of a non-federally owned conduit, such as 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 is not primarily for the generation of electricity.  To qualify, conduit facilities must have an installed generating capacity that does not exceed 10 megawatts (MW), and must not have been licensed or exempted from the licensing requirements of Part I of the Federal Power Act on or before August 9, 2013.  The Federal Energy Regulatory Commission subsequently issued Order No. 800, updating its rules to conform to the newly streamlined process.

While qualifying conduit hydropower facilities are not required to be licensed or exempted by the Commission, developers of qualifying facilities must file a Notice of Intent to Construct a Qualifying Conduit Hydropower Facility with the Commission.  On August 28, 2014, the City of Berlin, New Hampshire's Water Works filed such a Notice of Intent.  The proposed Ammonoosuc Water Treatment Plant Hydroelectric Project would have an installed capacity of 21 kilowatts (kW) and would be located on the existing 16-inch-diameter raw water transmission main immediately upstream from the pressure-reducing valve for the City of Berlin's water treatment plant.  The project would have an estimated annual generating capacity of 85 megawatt-hours.

The newly streamlined process can work quickly.  On September 10, Federal Energy Regulatory Commission staff issued a preliminary determination that the proposal satisfies the requirements for a qualifying conduit hydropower facility, which is not required to be licensed or exempted from licensing.  The Commission then posted this preliminary determination for public comment for 45 days.

No public comments were received, so on October 31, Commission staff issued its written determination that the Ammonoosuc Water Treatment Plant Hydroelectric Project meets the qualifying criteria under section 30(a) of the Federal Power Act, and is not required to be licensed under Part I of the Federal Power Act.

With this finding in hand just 64 days after filing its application, the city water department can continue securing the remaining approvals necessary to develop the Ammonoosuc Water Treatment Plant Hydroelectric Project.  Securing a FERC hydropower license can be a major endeavor, so the streamlined regulatory treatment now available to qualifying conduit hydropower facilities can be a major advantage.  How many other water treatment plants and other conduit owners will follow the Berlin Water Works' path and develop their own hydroelectricity assets using this easier regulatory process?

FERC Order 800 eases hydropower regulations

The Federal Energy Regulatory Commission has issued an order streamlining its regulations for some small hydropower projects.  FERC Order No. 800 conforms the Commission's regulations to the Hydropower Regulatory Efficiency Act of 2013.  Between Order 800 and the Hydropower Efficiency Act, regulatory processes for developing some small hydropower projects have recently become easier.

Hydropower is one of the nation's most abundant sources of renewable energy -- and yet about 97 percent of the estimated 80,000 dams in the United States do not generate electricity.  While not all are great candidates for hydropower, some non-power dam sites offer significant opportunities to generate renewable electricity with minimal incremental environmental impact.

Congress had these dams in mind when it enacted the Hydropower Efficiency Act on August 9, 2013.  To encourage the use of these dams for electric generation, the Act aims to reduce the costs and regulatory burden on project developers during the project study and licensing stages.  In particular, the Act amended previous statutory provisions covering both preliminary permits and projects that are exempt from licensing.  These statutory changes prompted FERC to update its regulations to conform to the Hydropower Efficiency Act.

Order No. 800 formalizes the Commission's compliance procedures in its revised regulations on preliminary permits, small conduit hydroelectric facilities, and small hydroelectric power projects, and in a new subpart on qualifying conduit hydropower facilities.  Key changes include:

• New regulations recognize the Commission's new statutory authority to extend a preliminary permit once for not more than two additional years, allowing permittees up to 5 total years to complete their feasibility studies without facing possible competition for the site from others.
• Exempt small conduit hydroelectric facilities may now be located on federal lands, and all exempt small conduit hydroelectric facilities may now have an installed capacity of up to 40 megawatts.  Previously, non-municipal small conduit exemptions were limited to 15 megawatts.
• Exempt small hydroelectric power project facilities may now have an installed capacity of up to 10 megawatts.
• Qualifying conduit hydropower facilities, which do not require licensure under the Federal Power Act but do require the filing with FERC of a notice of intent to construct, are now covered under the regulations.

While several of these categories of facility appear similar, each is defined separately by statute.

• A small conduit hydroelectric facility, as defined in section 30 of the Federal Power Act, is an existing or proposed hydroelectric facility that utilizes for electric power generation the hydroelectric potential of a conduit, or any 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.
• A small hydroelectric power project, as defined in the Public Utilities Regulatory Policies Act of 1978 (PURPA), is a project that utilizes for electric generation the water potential of either an existing non-federal dam or a natural water feature (e.g., natural lake, water fall, gradient of a stream, etc.) without the need for a dam or man-made impoundment.
• A qualifying conduit hydropower facility, as defined in the Hydropower Efficiency Act, is a facility that meets the following qualifying criteria: (1) the facility would be constructed, operated, or maintained for the generation of electric power using only the hydroelectric potential of a non-federally owned conduit, without the need for a dam or impoundment; (2) the facility would have a total installed capacity that does not exceed 5 MW; and (3) the facility is not licensed under, or exempted from, the license requirements in Part I of the FPA on or before the date of enactment of the Hydropower Efficiency Act (i.e., August 9, 2013).

In Order 800, the Commission is merely formalizing several practices it has already adopted since the enactment of the Hydropower Efficiency Act.  For example, the Commission has issued two-year extensions to preliminary permit holders, granted a small conduit exemption on federal lands, and issued conduit facility determinations on whether proposed projects are qualifying conduit hydropower facilities.  Nevertheless, the Act and Order No. 800 work together to offer an easier regulatory path for developers of small hydropower projects without new dams.
