Eldora Energy LLC is a 400 MW hybrid power plant located in Matagorda County, Texas. The plant, owned and operated by Eldora Energy LLC, a subsidiary of the Swiss company Advanced Power, utilizes both battery storage and solar photovoltaic technologies. It consists of two generators and is fueled by MWH (presumably electricity from the grid, given the battery component). The solar array uses a fixed tilt tracking system.
Eldora Energy LLC operates within the Electric Reliability Council of Texas, Inc. (ERCOT) balancing authority and the TRE NERC region. It is ranked as the 29th largest power plant in Texas out of 224, and 99th nationally out of 514. The plant's hybrid nature and location in the ERCOT market have garnered some industry attention, as evidenced by two news articles, one focusing on deals and the other on general industry news.
