Battery Storage as a Layered Option
We layer battery storage behind the gas plant where it adds value to the offtake. We do not sell standalone utility-scale BESS.
Battery storage is a tool, not a product line. Inside our behind-the-meter offering, storage earns its place when it improves the operating profile of the gas plant or the economics of the offtake - not as a separate sale. The pages below describe the roles where storage actually adds value, the technical considerations that determine sizing and chemistry, and the limits we are honest about.
Roles Behind the Gas Plant
Fast-response capacity smoothing
Battery storage absorbs short-duration load swings that would otherwise force the gas plant to ramp aggressively or oversize for peaks. For AI and HPC ramp profiles in particular, storage can smooth the demand curve seen by the engines - reducing wear, improving heat rate, and keeping spinning reserve requirements modest.
Voltage and frequency support
Inverter-based storage provides fast voltage support, frequency response, and reactive power management at the POD. This is most useful where the offtaker has equipment sensitive to voltage and frequency events.
Ride-through during planned maintenance windows
During engine-level rolling maintenance, storage can carry transient demand changes so the offtaker does not see a degradation in delivered quality. Storage does not replace generation - it bridges short windows where rolling maintenance temporarily reduces available block capacity.
Black-start support
Storage can support controlled restart sequences after major events, energizing essential controls and accessory loads while the gas plant comes up.
Hybrid optimization
Where solar is layered behind the same plant, storage can shift solar production into evening peak windows and reduce the gas plant's marginal duty cycle.
Technical Considerations
Sizing is operational, not nameplate.We size storage to the operating problem we are solving - ramp behavior, voltage support duration, ride-through window - rather than to a marketing nameplate. A 20 MW / 40 MWh system that solves the actual ramp problem is more valuable than a 50 MW / 200 MWh system that doesn't fit the duty cycle.
Chemistry is selected against use case. Lithium iron phosphate (LFP) for most utility-scale and behind-the-meter applications because of safety profile, cycle life, and total cost. Other chemistries are considered where specific duty cycles or thermal envelopes require them.
Integration is engineered with the gas plant. Inverter coordination, protection, fault-duty contribution, and battery management system integration are designed against the same MV architecture as the gas block - not bolted on later.
Safety, fire suppression, and siting are designed against current NFPA 855 and UL 9540A guidance, with attention to thermal management, off-gas detection, and emergency response coordination.
What This Is Not
We do not sell standalone utility-scale battery energy storage systems for grid services, ISO market participation, or merchant arbitrage. Storage on our projects is sized and operated against the offtake - its job is to improve the customer's experience of behind-the-meter power, not to chase ancillary services markets.
