When in comparison with the utility-scale and residential markets, the put in capability of power storage in the neighborhood, industrial and industrial (CCI) market is woefully underdeveloped, particularly judged towards its potential.
Based on Wooden Mackenzie’s “US Power Storage Monitor” report, the grid-scale section deployed 6,848 MWh of storage in Q3 2023, the residential section put in 381.4 MWh and the CCI market managed 92.9 MWh. That “final place” standing will proceed for CCI, as the opposite two markets are predicted to outpace it past 2027.
However final place nonetheless will get paid, and contractors putting in batteries within the CCI section mentioned they’re as busy as ever, particularly in pro-storage states like California and Massachusetts. By way of a mix of schooling and policymaking, industrial storage adoption might proliferate extra rapidly throughout the nation.
How CCI storage is working already
Identical to with photo voltaic, California leads the nation in storage installations. And that can solely develop now throughout the NEM 3.0 period, which principally requires storage to be put in alongside photo voltaic for both expertise to make monetary sense for the shopper.
Elite Electrical, a non-residential photo voltaic and storage contractor in California, is engaged on a number of photo voltaic initiatives throughout the state, and every has storage paired. Carl Dawson, Elite president and CEO, mentioned the standalone storage ITC has been an enormous assist in getting extra CCI clients fascinated with storage, however NEM 3.0 has been the deciding issue.

“We’re retrofitting present PV methods so as to add extra power storage to allow them to change their interconnection agreements and get a greater profit out of the photo voltaic they have already got,” he mentioned. “The No. 1 cause you’d add power storage to a deal is … [solar-only] could have an ROI of 5 years, and you then return and though it prices extra so as to add a battery, that takes the ROI from 5 years to three-and-a-half years. That is extra frequent now with NEM 3.0.”
With out significant compensation for photo voltaic era, CCI clients in California notice their financial savings via auxiliary providers carried out by the battery — like demand shaving. Utilizing battery energy when their demand peaks retains clients in decrease demand tariff brackets, and cuts down on at the very least one fastened cost by the utility.
Utilities are additionally acknowledging the advantages of power storage for their very own grid resiliency.
“All through the US with totally different ISOs (unbiased system operators), they’re having a very exhausting time with reliability,” mentioned Billy Gamboa, senior director of power storage and EV charging for CCI undertaking developer DSD Renewables. “They’re getting extra involved in regards to the reliability of the grid due to the best way that electrical load and demand is rising, plus the elevated adoption of EVs each on the buyer facet and industrial facet.”

States and utilities are encouraging CCI storage purposes — whether or not it’s Massachusetts providing revenue-stack packages that DSD helps clients navigate, or Southern California Edison (SCE) working with Elite Electrical to reinforce its increasing grid.
“[Companies have] manufacturing services with huge masses in an space the place Edison can’t get to for 5 years, so we’re designing and constructing pilot packages,” Dawson mentioned. “We’re working with Edison on constructing these massive methods in order that once they do get their infrastructure on the market, we will help them with that part of the grid by exporting energy once they want energy.”
The Northeast is massive on providing further income streams via VPPs and greenhouse-gas emissions discount packages for battery house owners, and DSD finds that further compensation is commonly the preliminary cause why CCI entities look into storage.
“One undertaking, we have now a 1-MWh battery slated, and that’s going to mint like $75,000 in income from these packages every year. That’s phenomenal, along with no matter financial savings we get them with the battery behind the meter. And you’ve got the tax credit for the preliminary price of the methods,” Gamboa mentioned. “You are taking that every one collectively, and it’s a really compelling financial argument to go photo voltaic and storage.”
Room for enchancment
The 2 opposing coasts have largely discovered success in CCI storage adoption thanks to 1 vital truth — the precise insurance policies have been put in place.
“It’s important to have coverage regulation. You probably have policymakers [and] lawmakers who perceive the profit [of storage] and the way to work that into the regulation, you’ll be able to have that sort of assist,” Gamboa mentioned.

Extra states are proposing power storage targets, however their small quotas go away a lot to be desired. Michigan not too long ago signed off on a 100% renewable power objective by 2040 and carved out an power storage requirement — however solely 2.5 GW by 2030. By way of New York’s Local weather Act signed in 2019, the state has required 3 GW of storage by 2030, and Gov. Kathy Hochul instructed bumping that to six GW, however no official motion has been taken.
New York utilities Nationwide Grid and Con Edison have compensation packages for electrical energy clients that restrict their pull on the grid, however solely in summer time months. These “demand response options” and “sensible utilization rewards” don’t explicitly recommend utilizing power storage, however a battery’s software program controls assist make it occur. These restricted, seasonal monetary advantages do encourage CCI entities to discover power storage choices, however there are nonetheless roadblocks.
“Why isn’t extra storage being adopted? Typically it might be the complexity of the undertaking; possibly they aren’t seeing the financial profit. Perhaps the price of interconnecting will gobble up a whole lot of your finances and may cancel out the battery part,” Gamboa mentioned. “There’s a ton of regulation on the hearth security and dangerous supplies of batteries, particularly lithium merchandise, that must be taken severely. Typically it’s a timing factor — lead occasions are ridiculously lengthy.”
Generac’s commercial-sized ESS
One other impediment throughout the CCI market is the historic dependence on mills. Generator large Generac is aware of that fossil fuel-burning mills nonetheless have their place however acknowledges that batteries carry out higher in sure conditions. Generac launched its personal commercial-sized lithium ESS in early 2023.
“We see mills nonetheless being a core a part of the C&I area, and storage and mills complementing one another,” mentioned Hari Sivadas, VP of business battery storage options at Generac. “Storage responds a lot sooner than a generator when a blackout or brownout is detected, leading to a speedy transition from grid energy to backup energy when wanted, with out disrupting website operations. It isn’t sensible to dimension present lithium ion-based power storage for long-duration resilience. The objective is to restrict the usage of the generator, however with that gen-asset within the combine, one can select to not overbuild behind-the-meter storage.”
Generac additionally believes that battery makers want to raised clarify the expertise’s worth to each installers and end-customers.
“CCI is a posh market. Every website is totally different,” Sivadas mentioned. “There may be nonetheless restricted consciousness of storage each as a expertise and the worth it brings throughout the contractor, installer and engineering group supporting CCI initiatives. As OEMs, we have to frequently construct this consciousness with coaching, undertaking sizing/modeling assist, and so on., to make storage additional mainstream.”
The industrial market isn’t ignoring power storage, however it’ll take the efforts of policymakers, contractors and producers to push battery adoption additional. Modeling successes in California and the Northeast is an efficient first step to constructing out extra CCI storage.
