Dynegy gets two permits for wave energy parks off of California

The Federal Energy Regulatory Commission on Oct. 28 issued two preliminary permits, good for three years each, that will allow subsidiaries of Dynegy Inc. (NYSE: DYN) to explore the feasibility of two wave energy parks.

These wave parks would be located in the Pacific Ocean off of southern California, and would interconnect with the transmission system for the shut Morro Bay gas-fired power plant of Dynegy, located on the adjacent shore. Under these permits, Dynegy doesn’t have to worry about a competitor seeking approval for a project at these sites.

The projects are:

Dynegy Point Estero Wave Park

On Feb. 7, Dynegy Point Estero Wave Park LLC filed an application for a preliminary permit to study the feasibility of the Point Estero Wave Park Project. The requested project boundary comprises approximately 5.2 square miles (4-miles-long by 1.5-miles-wide) of coastal waters and lands located between 2.5 and 3.0 miles off the coast of San Luis Obispo County, California, and land near the town of Morro Bay.

Dynegy would develop the proposed project in a phased approach. First, under a demonstration phase, Dynegy plans to deploy a single approximately 1-MW GWAVE Power Generating Vessel (wave energy converter or WEC). Under a second phase, Dynegy plans to deploy 10 to 16 approximately 1-MW WECs. Finally, Dynegy plans to seek authorization to deploy additional WECs with a total installed capacity of 650 MW. In addition to the WEC’s, the project would consist of: anchors and mooring lines; submerged substations; submerged transformer buoys; two or more 10-mile-long, 230-kV alternating current submarine cables; and an existing 230-kV transmission line interconnecting with Pacific Gas and Electric’s switchyard facilities at Morro Bay.

Dynegy Estero Bay Wave Park

On Feb. 7, Dynegy Estero Bay Wave Park LLC sought a preliminary permit to study the feasibility of the Estero Bay Wave Park Project. The requested project boundary comprises approximately 2.73 square miles (1.0-mile-wide by 2.73-miles-long) of coastal waters located between 2.5 and 3.0 miles off the coast of San Luis Obispo County, California, and land near the town of Morro Bay.

Dynegy would also develop this proposed project in a phased approach. First, under a demonstration phase, Dynegy plans to deploy a single approximately 1-MW GWAVE Power Generating Vessel. Under a second phase, Dynegy plans to deploy 10 to 16 approximately 1-MW WECs. Finally, Dynegy plans to seek authorization to deploy additional WECs with a total installed capacity of 650 MW. In addition to the WECs, the project would consist of: anchors and mooring lines; submerged substations; submerged transformer buoys; two or more 2.5-mile-long 230-kV alternating current submarine cables; and an existing 230-kV transmission line interconnecting with Pacific Gas and Electric’s switchyard facilities at Morro Bay.
