The AES Hawaiʻi coal-fired power plant on Oʻahu is set to stop operations on Sept. 1, 2022.

Hawaiʻi’s only coal-fired power plant is set to end operations by Sept. 1 after three decades of use. There are concerns about delayed large renewable energy projects, which leave residents on the hook for higher energy costs. But just what is behind those delays?

The Conversation checked in on the state of Hawaiʻi's many large-scale solar projects. Nine solar and storage projects in development on Oʻahu have power purchase agreements with Hawaiian Electric. Seven of those are behind on their timelines. Meanwhile, Clearway Energy Group just opened Oʻahu's first utility-scale solar and storage plant in Mililani.
