US-based utility firm CenterPoint Energy is seeking approval to acquire 335MW of solar power capacity in Indiana under two power purchase agreements (PPAs).

The company’s electric and natural gas business, CenterPoint Energy Indiana South, has filed a request for approval from the Indiana Utility Regulatory Commission (IURC).

As part of the company’s long-term electric generation transition plan, CenterPoint Energy Indiana South is seeking approval to acquire 185MW of capacity from a solar project being developed by Oriden in Vermillion County.

The contracted PPA for the project is planned to cover a period of 15 years.

The second PPA, for a 20-year period, is for the acquisition of 150MW of solar capacity from a project being developed by Origis Energy in Knox County.

CenterPoint Energy Indiana Electric Operations senior vice-president Steve Greenley said: “These additional renewable resources would serve our local electric customers, providing a cost-effective, stable energy option.

“The additional energy obtained through the power purchase agreements will further [our] Smart Energy Future strategy.”

The two solar projects are planned to begin operations by 2023 subject to necessary approvals.

The company estimates that the total 335MW from the projects will be enough to power more than 70,000 homes, or 12,000 commercial customers, a year.

Mr Greenley said: “The additional energy obtained through the power purchase agreements will further CenterPoint Energy’s Smart Energy Future strategy.

“We’re pleased to be working with trusted developers in pursuit of continued renewable generation to support the communities we serve.”

In addition to these PPAs, CenterPoint is awaiting IURC’s approval for a proposal filed in February to acquire a 300MW solar project and an additional 100MW of solar capacity.

In June, the company also filed an application to build two natural gas combustion turbines to replace portions of its existing coal-fired generation fleet.
