Energy storageutility BESS, C&I storage, pumped hydro, long-duration

Grid-scale lithium-ion (mostly LFP) battery energy storage systems for arbitrage, capacity and ancillary services; behind-the-meter C&I storage; pumped storage hydro (PSP) as the incumbent multi-hour technology (~200 GW / 9,000 GWh globally); and emerging long-duration storage (iron-air, flow, CAES). Global battery storage spending reached ~USD 66bn in 2025. Capital risk is driven by Chinese cell supply and tariffs/FEOC rules, revenue cannibalisation, fire-safety permitting, and for PSP, geology, tunnelling and environmental clearance.

Regional notes

IndiaBESS VGF (4 GWh + ~30 GWh tranches) and ISTS waiver for storage drive record-low tariffs; mandatory 2h storage with new solar (advisory); ALMM-style localisation and ACC-PLI cells to follow. PSP is the long-duration backbone: ~4.7 GW operating with tens of GW under DPR/construction (Greenko, Tehri, JSW, Adani, Torrent, NHPC); CEA concurrence and forest/wildlife clearances are the critical path.
United StatesRecord deployments led by ERCOT/CAISO/Arizona; storage ITC retained under OBBBA but FEOC rules from 2026 and rising Section 301 tariffs on Chinese non-EV Li-ion batteries (25% from 2026) raise costs; local fire-safety moratoria after Moss Landing.
EuropeGermany, Italy (MACSE 10 GWh auction 2025), UK and Spain lead; capacity mechanisms and grid-fee exemptions; EU Battery Regulation adds due-diligence and carbon-footprint rules; PSP upgrades in Alps/Iberia.
Middle EastSaudi Arabia and UAE deploy multi-GWh BESS paired with giga-solar for RTC supply.

How Capibud uses this pack

A pack is a starting position, not a forecast. When a energy storage decision opens in Capibud, pack v1.0.0 is copied in and pinned to that decision. The 13 parameters, 9 swing factors and templates the committee saw stay attached to the decision record, even after the pack is next refreshed.

Parameter ranges and WBS durations seed the P50, P80 and P90 for capex, schedule and value. Your own estimates, vendor quotes and actuals replace pack defaults line by line, and the record shows which numbers are still defaults.

Each swing factor is wired to shared factors; here the heaviest are policy, construction materials, labour and electrical equipment. A move in one factor hits every exposed project in the same scenario, which is how the capital committee sees concentration across a book rather than project by project.

The 12 price feeds and 21 listed tickers feed the brain, which watches for drivers moving outside their pack range and drafts the change for a person to review.
