The key race: the last official gigawatt print is still Tesla's
Volume remains Tesla's October 2 print: 13.7 GWh of energy storage products deployed in the third quarter of 2026. Tesla did not split Megapack from Powerwall, and said deployments should not be relied on as quarterly financial results. It scheduled those results for after the close on October 21.
CATL's English news list on October 18 starts with an October 12 Battery Passport item and an October 10 Seres agreement, then a September 24 service-center post and the September 22 Debrecen trial-cell post. None of those headlines names a TENER Sodium customer, shipment, or acceptance.
ess-news reported on October 13 that CATL and Intilion signed a five-year agreement to develop up to 3 GWh of sodium-ion projects in Germany, Austria, and Switzerland. The article calls 3 GWh a development target and says neither company disclosed projects, procurement commitments, contract values, or delivery schedules. It also says a May 2025 partnership targeted up to 10 GWh in the same region, and that the companies have not said whether the sodium figure sits inside that earlier deal.
Who is ahead: QuantumScape's index still stops on October 8
QuantumScape's investor news index on October 18 still leads with two October 8 items, the QS PowerBlock introduction and the notice of third-quarter results after the close on October 21. The next older item is the July 22 second-quarter release. Those ledes do not name a paying customer, integrator, or volume offtake.
Tesla's 13.7 GWh remains the last official quarterly storage-deployment print among tracked members. Intilion's figure of up to 3 GWh is the development target described on October 13.
What decides it: EIA is still on the August file
The EIA-860M landing page still shows a September 24, 2026 release, August 2026 as the latest monthly file, and October 23, 2026 as the next release. Any change to Great River Energy's Cambridge battery row waits on that next file. The landing page is not a commercial-operation notice.
CATL's English headlines through October 18 still do not name a TENER Sodium cabinet. The new top item is a Battery Passport pilot, and the Seres item is a cooperation headline.
The money: a deployment print and a development target
Tesla's 13.7 GWh is the volume of energy storage products it says it deployed in the third quarter. Price, mix, and energy-segment profit wait on the October 21 results. The company said the deployment figure should not be relied on as an indicator of quarterly financial results.
Intilion's up to 3 GWh is a five-year development target in the October 13 ess-news report. The CATL headlines dated October 12 and October 10 do not state storage revenue.
What to watch through mid-2027
Watch whether CATL names a China TENER Sodium customer on its English newsroom, whether Intilion names a project site, and whether Tesla's October 21 results add a storage mix to the 13.7 GWh print.
Watch whether the October 23 EIA-860M changes the Cambridge battery row, and whether QuantumScape's October 21 results or a later release names a PowerBlock customer.
