Grid limits hobble data centers
U.S. electrical grid constraints are now delaying major data‑center projects and threatening Big Tech expansion plans as demand for capacity outpaces local supply. Meanwhile, the global boom in battery storage is outstripping the intelligence and operational frameworks needed to run fleets across markets, creating a fresh bottleneck in the energy transition.

Wood Mackenzie says the disclosed U.S. data‑center pipeline hit 241 GW at the end of 2025, while only 25 GW of new capacity was added to the development funnel in Q4 2025 — roughly half the Q3 pace. (woodmac.com) Sightline Climate’s Data Center Outlook tracks 777 hyperscale projects totaling about 190 GW announced since 2024 and finds just ~5 GW of the ~16 GW slated for 2026 is under active construction, leaving the authors projecting 30–50% of 2026 capacity may slip. (sightlineclimate.com) Interconnection queues are massive: interconnection.fyi’s live tracker shows 41,843 queue requests dating back to 1995, and Lawrence Berkeley Lab’s “Queued Up” aggregation covers queue filings that represent roughly 97% of U.S. installed capacity — while Enverus reports CAISO project timelines averaging close to eight years in some cases. (interconnection.fyi) Hyperscalers are vertically integrating to secure power — Alphabet closed its $4.75 billion acquisition of Intersect Power in March 2026 to bring generation and storage into its portfolio, and investors spun Intersect’s grid‑tied business into IPX Power, which holds about 4.4 GW of solar and 8.8 GWh of battery capacity in operation or construction. (abc.xyz) The battery boom is already large: BloombergNEF estimates nearly 94 GW of global storage additions in 2025 while California reported about 16,942 MW of battery storage available as of late 2025 — growth that industry analysts say outpaces current operational practices. (forbes.com) Industry and policy briefs warn the new bottleneck is software and market rules: Observer and sector analyses say fleets lack high‑resolution telemetry, aggregated dispatch logic and standardized market participation contracts, while the DOE has begun funding virtual power plant pilots to scale coordination across distributed storage resources.
