The rework of the credits is the IRA's "single most consequential and beneficial change," said EDP Renewables' Inurreta Acero.

Clarity on how the clean electricity production and investment tax credits will work is coming.
Included among the technologies newly recognized under the guidelines are hydropower, nuclear fission and fusion, geothermal, and others. Assuming the guidelines are finalized in something close to their current form, these will be eligible for the lucrative tax credits that solar and wind have already benefited from beginning next year. Those existing tax credits have amounted to up to 30% if all conditions are met.
And stand-alone storage will be newly eligible for the ITC specifically. This is one of the reasons that Inurreta Acero said the new rules will give developers more flexibility.
“In the past, the storage system had to be coupled with a generation unit, which limited our ability to capitalize on the fact that storage systems require smaller areas to be placed in service,” he said.
The reception from the industry has so far been warm. For instance, the American Clean Power Association said in a statement that the guidance “will help provide a stable, workable transition for energy market participants to the new emissions-based system for energy tax incentives.”
The IRS will officially publish the proposed guidelines on Monday, giving stakeholders until early August to comment. Those comments will inform the rules’ final form, expected later this year.
A public hearing will be held on the rules on August 12 and 13.
Under the IRA, solar developers have had the choice between the PTC and the ITC. Research from ICF found that the ITC has tended to be more beneficial to solar developers in most situations.
Asked whether the new rules will change how EDP Renewables considers which credit to use, Inurreta Acero said he anticipates they won’t, because the most important factor in that decision today is production (or capacity factor), which won’t be impacted by the tax credit.
“If production is high, a generating unit tends to financially benefit more from the PTC; if production is relatively low, the ITC tends to be a better choice,” he said.
Editor's note: This piece was updated on May 30 to fix a factual error in Rodrigo Inurreta Acero's quote about how EDP considers which credit to use. The most important factor is production/capacity factor, not local electricity prices.
