...The Kapolei Energy Storage Facility—basically an enormous battery—is being built to ensure a stable supply of electricity to the island of Oahu, which is preparing for the retirement of the AES coal plant—Hawaii’s last coal-fired power plant—which produces 15-20 percent of the island’s electricity.
The 185-megawatt storage facility was intended to make up for the loss of the 180 megawatt AES plant, which was no longer a viable option because of a recent ban on coal. But renewable energy projects have been beset by a number of problems, including delays in renewable projects....
...“If there is not enough solar, wind, or battery storage energy to replace the AES plant, HECO would have to use oil instead to charge things like the upcoming 185-megawatt Kapolei Energy Storage Facility,” Pacific Business News reported.
It’s not a matter of “if,” however. The reality is there’s not enough wind, solar, or battery storage to replace the AES plant. Hawaiian Electric has made this quite clear in recent documents, noting that it would not be able to meet its year-two renewable target (75 percent) for “more than a decade.”...
