Utah Celebrates Launch of Clearway’s 320 MW Energy Storage Portfolio, Strengthening Grid and Community Investment

Clearway Energy Group (“Clearway”) announced that it has brought online on the 320-megawatt (MW) Honeycomb Energy Center, marking a major achievement for Utah’s electric grid and local economy. This approximately $600 million investment in the Beehive State’s electric infrastructure features American-made Tesla equipment and 100% domestic steel, bolstering Clearway’s Utah portfolio to nearly 900 MW.

Honeycomb Energy Center includes four distinct 80 MW battery energy storage systems delivering 1,280 megawatt-hours of dispatchable power reserves to the region. The facilities are contracted under 20-year agreements with PacifiCorp, helping the utility reliably serve customers while advancing grid modernization. Each of the storage facilities are constructed adjacent to solar projects owned and operated by Clearway.

Senator John Curtis marked the occasion by attending the facility’s May 6 ribbon cutting event.

“The Honeycomb Energy Center represents a major investment in Utah’s energy future—supporting local jobs, strengthening grid reliability, and advancing energy innovation,” said Senator Curtis. “By pairing large-scale battery storage with nearby solar resources, we’re helping ensure dependable, affordable power for communities across the region. This project also highlights the critical role of energy storage in enabling renewable energy at scale, delivering reliable power when it’s needed most while supporting a more flexible and resilient grid.”

Battery energy storage systems store excess power supply for later release during times of high demand. By introducing flexibility into how electricity is dispatched, storage enables more efficient and stable operation of the grid to reliably serve customers and provide economic benefits.

“As one of Utah’s largest solar and energy storage operators, Clearway is supporting critical infrastructure in the state to help balance the grid and stabilize power costs,” said Clearway CEO Craig Cornelius. “We are proud to deliver storage capacity and its associated benefits at-scale in the Beehive State.”

As a leading renewable energy developer in Utah, Clearway boasts a two-decade-long operating history in the state, completing its first project in 2008. Additionally, Honeycomb builds on Clearway’s role as a long-term employer, taxpayer and philanthropic partner in Beaver and Iron Counties. In total, the Honeycomb projects:

• Will generate $60 million in property and sales taxes for schools and public services
• Created 150 jobs at peak construction, prioritizing local workforce opportunities
• Sustain more than a dozen full-time, family-supporting positions for local residents
• Support local landowners with long-term leases that help preserve their land and legacy

To mark commissioning, Clearway has made a $150,000 donation to Iron County Care & Share to support the launch of a Tiny Home Village, offering safe, stable housing for individuals transitioning out of homelessness. Clearway’s Utah staff have been proud supporters of the non-profit since 2023.

“We are deeply grateful for our first donation as we prepare to break ground on our tiny home project,” said James Jetton, Executive Director of Iron County Care & Share. “Our mission is to transform lives by extending our shelter into a community of tiny homes—offering not just a place to stay, but a meaningful stepping stone toward hope, healing, and long-term self-sufficiency.”
