According to a recent LinkedIn post from Eolian LP, the company is emphasizing regional disparities in the U.S. grid-scale battery storage buildout. The post cites reporting that Texas and California have seen rapid storage growth, while markets such as PJM, MISO, and SPP lag due to market design and revenue-certainty challenges rather than technology constraints.

The post highlights comments from CEO Aaron Zubaty suggesting that large-scale battery deployment in these markets requires both risk appetite and substantial equity, with the thesis that rising demand from new large loads could outstrip available supply. Eolian indicates it has been an early mover since 2017 in developing grid-scale storage in PJM, MISO, and SPP, including a 200 MW / 1+ GWh project near data center expansion outside Columbus, Ohio, targeted to be PJM’s largest battery facility when it comes online in early 2027.
From an investor perspective, this development pipeline points to potential long-term optionality tied to structural growth in electricity demand, particularly from data centers and other high-load users. However, the post also underscores policy and market-design risks, noting that evolving rules and politically driven interventions in wholesale markets could affect project economics, timelines, and ultimately returns.
If market reforms in PJM, MISO, and SPP move toward clearer capacity and ancillary service revenue streams for storage, Eolian’s early positioning in these regions could translate into competitive advantages and higher asset values. Conversely, prolonged uncertainty or adverse rule changes could delay commercialization, increase financing costs, and limit near-term cash flow visibility for battery projects, tempering the upside implied by demand growth trends.
The post further suggests that, once projects clear permitting and interconnection queues, grid-scale batteries can be deployed faster than other dispatchable resources, which may appeal to customers and counterparties seeking timely capacity additions. For investors tracking private infrastructure and energy-transition themes, Eolian’s focus on flexible storage assets in underbuilt markets could provide exposure to both the upside of power-demand growth and the downside risk of regulatory and market-structure volatility.
