Clearway Energy increases Utah ‘Energy Centre’ capacity to 2,120MWh
AI-summarised brief · reviewed before publication
Clearway Energy announced on 9 October that it has added 210 MW of battery energy storage system (BESS) capacity to its Honeycomb Energy Centre fleet in southern Utah, raising the combined storage capacity to 2,120 MWh. The expansion is backed by long‑term power purchase agreements with utility PacifiCorp and enables three new BESS facilities to move into the second phase of the Honeycomb project. Each 80 MW installation sits beside an existing Clearway solar plant, also contracted to PacifiCorp. The Honeycomb portfolio represents roughly a $600 million investment, financed in March 2025 by a consortium led by KeyBanc, CoBank, DNB, and others. Construction, led by Rosendin, is expected to create at least 150 jobs and generate $37 million in tax revenue for Beaver and Iron counties, plus annual community donations.
💡 Why It Matters
- · The added storage capacity deepens Utah’s grid flexibility, allowing more solar output to be captured and dispatched when demand peaks, directly supporting PacifiCorp’s reliability goals.
