Expansion at the waste-to-energy facility provides relief for landfills and eases the cost of electricity
Sandwiched between an oil refinery and a coal-fired power plant in Campbell Industrial park sits Hawaii's largest producer of electricity from renewable energy.
The often overlooked facility doesn't have any solar panels or wind turbines. A steady stream of garbage trucks lining up to disgorge their loads reveals the facility's fuel source: trash.
Hawaiian Electric Co. has put online graphs that show how much solar and wind power is being generated on Oahu, Maui and Hawaii island throughout the day and how much the renewable sources contribute to total power consumption.
The utility wants consumers to understand the variable nature of solar and wind power and the important role of the so-called "firm" power generated at HECO plants.
"To maintain reliable electric service for all customers, utility engineers must adjust the output of firm sources of generation up or down as the output from variable sources like solar and wind rises and falls throughout the day," HECOsaid in a news release.
