It's Wednesday. Lithium gets the headlines, but the grid's longest shifts may fall to older and stranger chemistries. One of the world's biggest power markets just put real money behind two of them at once.

The Big Story
India awards pumped-hydro contracts and its first grid-scale flow battery
India's Solar Energy Corporation (SECI) awarded 1,344 MW of pumped-hydro storage to Tata Power, Greenko, and Torrent through a competitive reverse auction, while startup Delectrik won a separate tender to build a 100 MWh vanadium flow battery at the giant Khavda renewable park in Gujarat. The pumped-hydro developers take long-term power-purchase agreements on a build-own-operate basis. Energy-Storage.news reported that the Delectrik award, made with partner Bondada Engineering, is the country's first utility-scale flow battery and is due for deployment next year.
"The first utility-scale flow battery project is a milestone not just for the company but the country as a whole."
Greenko won its full 720 MW bid, Torrent took 300 MW, and Tata Power was awarded 324 MW of the 660 MW it sought, all on long-term PPAs.
Delectrik's 100 MWh vanadium redox flow battery will sit at the 30 GW Khavda park in Gujarat, which already runs about 10 GW of solar and wind, under a tender from NTPC Renewable Energy.
India has 11 pumped-hydro projects totaling 15,870 MW under construction, with another 8,140 MW approved and awaiting a start, according to the government's Press Information Bureau.
The Central Electricity Authority's national plan projects India will need 74 GW / 411 GWh of storage by the 2031-32 financial year, split between batteries and pumped hydro.

Quick Hits
Small bites from across the grid.
Four datable moves from across the stack in a quiet mid-July window.
Gridmatic said its analysis found California batteries left roughly $98 million on the table by running static, "set it and forget it" bidding instead of optimizing dispatch in CAISO. Energy-Storage.news

Crusoe and ON.energy will deploy 5 GW of medium-voltage "AI UPS" across US hyperscale campuses, gear that rides through voltage faults and keeps GPU load swings off the grid, with commissioning running through 2026 into 2027. Manila Times
Fermi said the first three Siemens SGT6-5000F gas turbines, rated up to 780 MW combined, arrived at the Port of Houston bound for its Project Matador AI campus near Amarillo, Texas. Yahoo Finance
The Capital Stack
European developers lock in long-term tolls to make merchant batteries bankable
Two deals signaled that Europe's merchant storage market is edging toward contracted revenue. Return and Engie agreed a 10-year toll on 55 MW/220 MWh of Spanish BESS, while EnBW took 300 MW of Zelestra's 500 MW/2,000 MWh Italian project under a long-term toll, according to Energy-Storage.news. Tolling deals hand developers predictable cash flow and give lenders something to underwrite, a structure that has been scarce across Europe's largely merchant battery fleet.

Policy Watch
Western utilities are making progress on large-load tariffs that dictate how data centers and other big new customers pay for capacity and grid upgrades, RTO Insider reported, a template other regions are watching as they try to add gigawatt loads without shifting costs onto existing ratepayers. RTO Insider
FERC ordered NERC to write binding reliability standards for large computational loads and to register data centers as grid entities by the end of 2026, a first that pulls hyperscale sites directly under the mandatory reliability framework after fast load swings raised voltage-stability concerns.

Johannes Pfeifenberger on planning the grid for surging large loads
Johannes Pfeifenberger asked, "How do you plan a grid for this???", pointing to a new ESIG report on transmission planning for large loads. His argument: planning frameworks built for incremental growth cannot connect data centers and other big loads quickly while keeping long-term transmission cost-effective.
The report's eight recommendations run from better visibility into transmission headroom, advanced transmission technologies, and planning for load flexibility and co-located resources, to consolidated planning, scenario-based least-regrets methods, proactive multi-driver planning, development zones for large loads, and interregional transmission.
