Continuing a transitional push toward cleaner power, Duke Energy this week put out a call for proposals of new and diverse power generation sources to provide for its Indiana customers.

“This gives us an opportunity to hear from developers about what may be available,” Stan Pinegar, Duke Energy Indiana president, said. “Our aim is a responsible transition to cleaner power for customers who count on us to deliver energy that is affordable and available whenever needed.”

While a variety of resource locations are viable, the request laid out a clear preference for those deliverable to the Midcontinent Independent System Operator (MISO) Zone Six. Existing resources or proposals for new resources are both acceptable, but either way, they need to be in-service no later than Dec. 31, 2032, to be considered.

Specifically, Duke is eyeing up to 2,500 MW of intermittent generation from solar, wind or other commercially viable renewable energy technologies. Combinations with battery storage are also fair game. On top of this, it called for up to 2,500 MW of non-intermittent generation, meaning generation dispatchable on demand, such as those from natural gas combustion turbines, combined cycle units or stand-alone battery storage.

In theory, such proposals could take many forms. Duke Energy opened the door to the possibility of power purchase agreements, facilities built for transfer to Duke’s ownership or existing items to be purchased outright by the company. Either way, all proposals for intermittent generation will be due by Feb. 9, 2024, but those for non-intermittent generation will have until Feb. 23, 2024.
