Hawaii Electric Light has submitted its monthly report to the Hawaii Public Utilities Commission (PUC) June 8 outlining its power generation from renewable energy units for May.
The utility is a Hawaiian Electric Industries (NYSE:HE) company. The parent company has proposed going 100% renewable gradually over 30 years – although liquefied natural gas (LNG) would remain an option at least in the near term.
The reports to the PUC are evidently required under a power purchase agreement with the Puna Geothermal Venture.
The report provides the curtailment start and end times, the megawatt output of the facility prior to start of curtailment and after curtailment released, and reason for curtailment.
The report also includes log sheets that show generation on the HEL system at the top of the hour for periods when it became necessary to curtail the output of renewable generation due to oversupply.
The wind farms generally return immediately to full available levels when operation resumes, the utility said.
