It's been officially a year since the Inflation Reduction Act was enacted, so it's no surprise that looking at the IRA's impact dominated the discussion at a recent industry event.

The second annual Renewable Energy Leadership Conference, presented by Renewable Energy Alliance Houston and Rice Business Executive Education, featured thought leadership from 20 experts on Tuesday, August 22. While some panels zeroed in on hiring and loan options for energy transition companies, the day's program kicked off with a couple panels looking both back and forward on the IRA.

When looking at the IRA's impact, the experts identified a few key things. Here's what they said at the conference.

Going beyond tax credits and regulation

Greg Matlock, EY's global energy and resources industry tax leader, kicked off the IRA discussion after John Berger, CEO of Sunnova, gave a keynote address.

Matlock set the scene for the IRA, explaining that previous legislation incentivizing clean energy changes mostly stayed within regulation and tax credits. Credits as a tax policy fail to incentivize organizations that are, for various reasons, are tax exempt or are already paying insignificant taxes. The fundamental switch of the IRA was to a "want to" rather than a "have to."

"Everyone has had aspirations, but with aspirations without capital, it's hard to get movement," Matlock says. "But what the IRA did was create a liquidity in the market and added access to an investor base. Now you're pairing aspirations and capital, and now you're seeing movement in the market."

The IRA, Matlock continues, also got the ball rolling on expanding requirements for tax incentives. Previously, a specific technology has to be clearly identified to be qualified for a credit. Moving forward, the IRA improved this qualification process and in the future, there will be be technology neutral incentives.

One thing Matlock also highlighted was the limitations of tax credits — dollar for dollar credit.

"Two years ago, if you called an organization that was tax exempt (about) a project that generates tax credits, why would that want that?" Matlock says. "For the first time, you can sell federal tax credits — not all of them — for cash and tax free to businesses who are paying taxes."

Explaining that there are limitations, Matlock says this process had a significant impact encouraging movement in this space — especially from surprising sources.

"We're seeing companies that have absolutely no connectivity to our energy industry making investments through the purchase of tax credits to fund the development of projects," Matlock says.

A focus on carbon capture and hydrogen

Matlock continues to explain how carbon capture and hydrogen became two case studies for the impact of the IRA.

Prior to the IRA, over 16 countries incentivized hydrogen production, he explains, and the United States was not one of them.

"With the signing of the IRA, we went from the worst to the first," Matlock says.

Carbon capture development was directed more at traditional energy industries. The IRA enactment represented a switch for these companies from regulatory moves to incentivization, which has been more effective in general, Matlock says.

Over the past year, according to the American Clean Power Association, more than $271 billion in investment in clean energy projects has occurred since the IRA was enacted. When it comes to jobs, over 170,000 clean energy jobs have been announced since the IRA.

Problematic permitting and pricing volatility 

In a subsequent panel, the three thought leaders looked at the IRA a bit more critically. While the IRA spurred momentum, it also shined a spotlight on some of the industry's challenges.

"The IRA for developers has been very positive. It provided certainty and allowed developers and investors alike to plan long term," says Omar Aboudaher, senior vice president of development for Leeward Renewable Energy. "With that comes challenges, including exacerbating some existing problems with permitting."

Aboudaher explains that the IRA-inspired burst of projects has caused a lot more permits for the increase of development. And, he adds, there's not a concentrated effort. It's happening in silos on the various levels of government.

"On the permitting side, there's a big need to streamline permitting," Aboudaher says. "In some parts of the country, it can take 6 to 10 years to permit your project."

On the investor side, it's also a problem, adds Fred Day, managing director of investments at Brookfield Asset Management.

"Even though we have this IRA, a lack of permitting reform does create a bottleneck," he says.

Another challenge is a disconnect between supply and demand. While the IRA has incentivized solar energy generation per hour of energy, meaning that its cheaper than ever to make energy via solar panels, there's not yet the demand infrastructure for this energy. This incentivization structure has already been in place for wind power.

"I think it's going to be a real problem. It's a real problem with wind today," Doug Moorehead, COO of Broad Reach Power, says, explaining that there's volatility in pricing. "When the wind is high, prices are really low. When wind is low, prices are high."

All of this is leading to an imbalance of market demand and supply, he continues. Jessica Adkins, partner at Sidley Austin LLP and moderator, adds that there's built in volatility for solar since solar energy is confined to the time of day when the sun is out.

"Any time you're incentivize to produce regardless of demand, it's going to be an issue," Moorehead says.

According to Flatter, Greentown alumni raised more than $2 billion this year and created more than 3,000 jobs.

"Greentown startups and ecosystem leaders—from Boston, Houston, and beyond—are showing that we can move further and faster together. That we don’t have to choose between more energy or lower emissions, or between increasing sustainability and boosting profit. I call this the power of 'and,'" Flatter added. "We’re working for energy and climate, innovation and scale, legacy industry and startups, prosperity for people and planet. The 'and' is where possibility expands."

NRG makes latest partnership to grow virtual power plant

VPP partners

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
