I didn’t even know Hawaii had a coal power plant! At 16% total, that is a ‘peaking plant’ at the Kapolei industrial area. They also have a rubbish burning plant, and a Nat. Gas peaking plant there. The REAL power for Honolulu and Oahu island is two large oil-fired plants. But thankfully, I’m not on that over crowded island any more.
Here on the Big Island oil is also the mainstay, but they are trying to get approval for a wood burning plant to burn the huge eucalyptus pole tree forests planted up north to fuel that. We have geothermal from the volcano that supplies about 20% of the island needs, and we even have a small hydro plant on the Wailuku river in Hilo that provides a few percent. Last year when we had Russian oil, my electricity was around $0.37/kwh. Now we have to get more expensive oil from indonesia. Last month my bill was at $0.5625/kwh. Been going up every month. Makes my leased solar PV system a real bargain now!
