Dynegy ends permits for wave energy projects off of retired Morro Bay plant

The Federal Energy Regulatory Commission said in two Oct. 4 notices that affiliates of Dynegy (NYSE: DYN) have decided to drop preliminary permits issued by FERC in 2014 for two wave energy projects in the Pacific Ocean off of California.

  • Under Project No. 14584, Dynegy Point Estero Wave Park LLC had proposed the Point Estero Wave Park Project. The preliminary permit, covering up to three years of project feasibility work, was issued in October 2014, and would have expired on Nov. 1, 2017. The project would have been located in the Pacific Ocean between 2.5 and 3.0 miles off the coast of San Luis Obispo County, California, and on land near the town of Morro Bay. The preliminary permit will remain in effect until the close of business on Nov. 3, 2016. But, if the commission is closed on this day, then the permit remains in effect until the close of business on the next day in which the commission is open. New applications for this site may not be submitted until after the permit surrender is effective.

These wave parks were to interconnect with the transmission system for the shut Morro Bay gas-fired power plant of Dynegy, located on the adjacent shore. More details on the now-abandoned projects are:

Dynegy Point Estero Wave Park

Dynegy Point Estero Wave Park LLC wanted to study the feasibility of the Point Estero Wave Park Project. The 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 was to develop the project in a phased approach. First, under a demonstration phase, Dynegy was to to deploy a single approximately 1-MW GWAVE Power Generating Vessel (wave energy converter or WEC). Under a second phase, Dynegy was to deploy 10 to 16 approximately 1-MW WECs. Finally, Dynegy planned to seek authorization to deploy additional WECs with a total installed capacity of 650 MW. In addition to the WEC’s, the project was to 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

Dynegy Estero Bay Wave Park LLC has a preliminary permit to study the feasibility of the Estero Bay Wave Park Project. The 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.
