Your Data Center Modules Ship in Weeks. Your Power Won’t Be There Until 2030.
Let your data center run more compute on less grid and get online sooner with B2U BESS that ships in less than 6 months.
Need Power Now? B2U has a portfolio of energized sites in Texas and California with up to 10 MW per site available for data centers today.
Every data center needs to clear three C’s:
Capacity
Utilities in constrained markets are quoting four to seven years for new large loads, and on-site gas turbines and engines are booked into 2028–2030.
Cost
Missed revenue from online delays is the most expensive issue today, and power is the biggest lifetime operating cost, with rates and large-load charges on the rise.
Community
Utilities, regulators and neighbors increasingly decide who connects, and when. Data center developers need to overcome “not-in-my-backyard” concerns.
B2U bridges the gap between the power you have and the power you need.
Capacity
Energy storage lets you run more compute per MW of capacity, connect sooner on a flexible service, and combine with onsite generation to bridge power before your grid connection arrives. With 6-month lead times, B2U BESS ships years ahead of new gas equipment and faster than backlogged new storage.
Cost
Earn revenue sooner and pay less for power. Storage pulls your online date forward, then keeps on paying. Lower demand and capacity charges, protection from rising rates, and grid revenue when idle. B2U energy storage systems are up to 50% less than comparable new systems.
Community
Lead with grid-friendly, flexible load that doesn't drive up electricity prices or ask rate-payers to cover the cost of grid upgrades. Ride-through for hours with no onsite combustion, bringing a more community-focus solution with energy storage.
What do B2U energy storage solutions do for your data center?
Energy storage provides power during peak periods, avoiding curtailment, to maximize available grid capacity.
More GPU per MW
Ride through
Connect sooner
Accept flexible service and keep running with energy storage. Pair with onsite generation to bring your own power ahead of grid upgrades.
Lower lifetime cost
Reduce demand and capacity charges, offset power costs with grid services when battery is idle, and hedge against rising rates.
Less capital at risk
Manage BESS design uncertainty with up to 50 % lower upfront capital costs than comparable new systems.
Right size onsite gen
Carry step loads, firm renewables, cut backup runtime, and reduce permit exposure.
Add hours of clean and quiet backup outside your critical power path.
Data center leaders are already build-in BESS
Recent headlines show how data center developers already depend on energy storage to address their power needs:
Powered land for your modular data center. Available now.
B2U operates grid-connected battery energy storage sites with interconnection capacity to spare. We carve out up to 10 MW per site for your data center, so you plug into power that's already studied, built and flowing instead of joining a years-long queue to connect.
5+ sites in Texas (ERCOT) and California (CAISO) are available now, with proximity to fiber, ample space, and battery storage on site. So, your first compute loads can get online in 2027. And we're actively acquiring more operating sites, so additional capacity becomes available in months, not the years associated with a ground-up build.

Frequently Asked Questions
-
B2U battery storage lets a data center start before the grid can fully serve it: stretching capacity on a partial grid connection, under flexible service where the utility offers it, or alongside onsite generation to bring your own power online before grid capacity arrives. B2U energy storage solutions ships in about six months.
-
Grid connections are sized for peak draw, but data center load runs below peak most of the time. B2U energy storage solutions covers the peaks, so you can size power infrastructure to what you actually use and bring more compute online within the same power capacity.
-
B2U delivers our energy storage solutions in 6 months or less, drawing on more than 1,150 MWh of batteries already under management. Compare that to the years it takes to navigate the long backlogs for new stationary storage, onsite gas turbines and engines (booked into 2028–2030), and large transformers (three years or more).
-
It depends on your load, your grid connection, and your goal. Most sites need two to four hours of capacity a day during a portion of peak load. Ask for a free sizing consult.
-
There are several benefits energy storage brings to lower the cost of electricity once a data center is online. Mainly, it lowers demand and capacity charges, protects against rising rates and large-load charges in the future, and offsets costs with grid services, earning revenue when idle. B2U energy storage systems cost up to 50% less than comparable BESS with new DC blocks.
-
Sometimes. Flexible connections are growing for large loads in some regions, but the rules for data centers are still being written and differ by utility, state, and grid operator. Where flexible service is offered, B2U energy storage solutions can carry your load through curtailment hours, so compute keeps running. Where it isn't, energy storage can provide the backup and limiting capabilities that utilities and regulators increasingly expect new large loads to bring.
-
Battery energy storage carries benefits that matter to utilities and to communities: a load that can reduce its draw when the grid is stressed, reduce expensive distribution buildout that raises rates for everyone, backup for hours with no onsite combustion, less diesel runtime and fewer air-permit issues, and quiet operation.
-
No. B2U energy storage solutions sit between the utility and your facility, on your side of the utility meter but outside the critical power path. Your UPS and backup design stay as they are.
-
B2U has operated battery energy storage systems built from automaker EV packs since 2020, with ~100 MWh in service at 99% fleet uptime. Capacity, availability and efficiency guarantees are insured by AXA, with coverage attested by New Energy Risk, and Black & Veatch has independently assessed our systems. Systems are UL 9540 / 9540A certified
-
B2U Storage Solutions owns and operates grid-connected battery storage sites with up to 10 MW each available for modular and edge data centers, with proximity to fiber, ample space, and battery storage onsite. The first five sites in Texas (ERCOT) and California (CAISO) are available now, so your compute loads can get online in 2027, with more operating sites being acquired. Site details are shared under NDA.
