Texas developer secures 10 GWh+ of BESS capacity to supply data centers
Texas-based renewable energy developer Greenflash Infrastructure has secured more than 10 GWh of lithium-ion battery energy storage capacity, which has been earmarked for data center power needs.
Greenflash offers a single-contract structure for data center developers that is similar to an EPC provider in the renewable energy sector. Its data center design model, launched in October 2025, covers design, construction coordination, and operational readiness in line with ERCOT electricity grid standards.
The company says it is targeting a 5 GW ERCOT buildout in Texas. In October 2025, it introduced a design framework intended to help developers of large-load data centers across the ERCOT market expedite the permitting process and connect to the grid.
The company claimed its approach is in line with ERCOT reliability standards and provides a straightforward path to SB6 compliance and operational readiness.
“Data centers are becoming part of the grid itself,” said Ben Yang, Chief Technology Officer of Greenflash last October. “We’ve built a framework that makes grid compliance straightforward and scalable. Those who align early will set the standard for what ERCOT-ready design looks like.”
Its framework approach revolves around a ‘data center shell’ design that includes pre-approved protection schemes and reserved space for integrated BESS. It combines BESS with grid-forming controls to maintain stability and incorporates an integrated operations platform to manage dispatch, telemetry and compliance reporting.
The company said it was working with developers entering design in 2025 to align on SB6-compliant, market-ready infrastructure. It is also working on pilot deployments in 2026.
The 10 GWh+ of BESS capacity it has secured will be added to its pipeline which includes more than 1 GWh of battery supply ready for near-term deployment and a further 2 GWh scheduled for delivery in March 2026.
“In today’s environment, delivery timelines and incentive eligibility are increasingly shaped by supply-chain and policy considerations,” said Vishal Apte, Managing Partner at Greenflash Infrastructure. “By pairing a substantial safe-harbored equipment position with readily deployable inventory, we have reduced execution risk for our partners and positioned projects to advance efficiently as interconnection pathways and market conditions evolve across ERCOT and other key markets.”
Developers added 45 GW to US project pipelines in the third quarter of 2025, according to a Wood Mackenzie Q3 data center report. The industry is shifting toward energy parks that integrate solar and battery storage on site.
The US planned solar and storage pipeline reached 245 GW of planned capacity as of mid-October. The growth is driven by speculative projects and renewable deals signed by hyperscalers, said the report. Texas accounts for more than a quarter of pipeline capacity. The pipeline in the state nearly doubled from 35 GW in the first quarter to 67 GW in the third quarter.
Greenflash accounts for some of that capacity in ERCOT. It is developing the 400 MW/800 MWh Project Soho standalone BESS in Brazoria County in Texas. It closed a hybrid capital and debt financing deal for the battery in October 2025, which saw participation from Deutsche Bank as debt financier and coordinating lead arranger, as well as a preferred equity investment from Acadia Infrastructure Capital and Wafra. The preferred equity investment was structured to facilitate a tax credit sale to a leading United States insurance company.
At the time the deal was announced, Greenflash said the Soho Project was ahead of schedule to energize in the first quarter of 2026, with commercial operations set for the second quarter of the year.
Also in October 2025, Greenflash acquired Rock Rose, a 200 MW/400 MWh pre-notice-proceed BESS from Advanced Power. Located in Texas’ Fort Bend County, it is targeting commercial operations for mid-2027.
