Sunrun has recently partnered with Voltus to support a new initiative that integrates capacity from residential solar-plus-storage systems into the energy supply for AI hyperscalers in the PJM and MISO grid regions. Under this collaboration, Sunrun will provide resources from its extensive network of residential systems, although the specific details regarding capacity, participating homes, and target projects were not disclosed.
Mary Powell, CEO of Sunrun, emphasized the importance of optimizing energy production to meet increasing demands, stating that collaboration with Voltus is a step toward delivering essential capacity through home batteries backed by funding from hyperscalers.
Voltus has initiated its Bring Your Own Capacity (BYOC) program, which enables large users like hyperscalers to contribute flexible capacity that will support the grid and facilitate the connection of data centers. The program aggregates distributed resources such as batteries and smart thermostats, allowing homeowners and businesses to receive compensation for their participation.
However, there’s a critical distinction to be made between capacity and physical grid capability, which can impact how effective this partnership is for individual data centers. Rob Gramlich, founder of Grid Strategies, noted that while distributed resources can provide effective generation supplies, data centers often need to generate their own energy. Additionally, the separation of transmission access in regions with independent operators can create challenges.
Neil Osnato, founder of Persistence Analytics Group, explained that while residential batteries can form a dispatchable resource, their effective capacity hinges on market rules and the reliability of the aggregated supply. Therefore, a BYOC portfolio may fulfill resource requirements without addressing the physical limitations that prevent specific data centers from connecting smoothly to the grid.
A precedent for this model was set with a previous agreement between Voltus and Google, which aimed to harness up to 100 MW of distributed capacity within PJM for three years, focusing on various residential assets.
This agreement with Sunrun broadens the potential resources available to Voltus but does not clarify whether the capacity is newly sourced or currently participates in regional markets. Notably, the evolving dynamics illustrate a trend where hyperscalers are beginning to extensively engage in distributed capacity procurement, recognizing its potential beyond conventional utility programs.
Despite its advantages, experts caution that distributed resources shouldn’t replace necessary grid infrastructure, as they cannot resolve issues like inadequate transmission capacity or voltage stability. As we see legislative efforts sprouting in states like New Jersey to advance these types of arrangements, the ongoing discourse will revolve around ensuring adequate energy supply for the growing demands of data centers.
