🧭

What this board is This is a living board, not a static memo. The goal is to create one working source of truth where live signals, regulation, project activity, and your own judgment can sit together in the same place. How it should be used The board is meant for real work: tracking what changed, capturing conclusions, comparing evidence, and building a current view rather than losing context across documents and chats. Why the chatbot matters The chatbot can query the full board context across notes, managed feeds, and structured content, so it can help answer questions, surface patterns, and work from the same evolving knowledge base as the user.

US Federal Regulation

Energy Department | Order No. 917 | FERC has issued guidance on changes to the Electric Quarterly Report (EQR) filing process, primarily reducing certain reporting requirements and outlining a future transition to a new data system. What Changed & Why it Matters for Battery Storage and Grid Infrastructure: Reduced Reporting Burden (Effective May 26, 2026): Filers will no longer need to report specific data points related to transmission capacity reassignments, transactions reported to index price publishers, or the use of exchange/brokerage services. This change applies to Q2 2026 EQR filings (due July 31, 2026). For battery storage and grid infrastructure operators, this means a slight reduction in the administrative burden of EQR compliance, particularly concerning certain transmission-related data. Billing Adjustments: Material billing adjustments must now be reflected through an EQR refiling, rather than using a specific "Billing Adjustment" reporting option. This clarifies and standardizes how such adjustments are handled. Future Data System (XBRL-CSV): FERC is developing a new XBRL-CSV system for EQR submissions to enhance data standardization and accessibility. While no implementation timeline is set, FERC will engage industry through draft taxonomies, technical guidance, and conferences, providing ample time for software development and testing. This future system could eventually improve the transparency and analysis of wholesale market data, which is relevant for understanding market opportunities and operational trends for battery storage and grid assets. Who is Affected: All entities currently required to file EQRs, including wholesale power sellers and transmission providers, which encompasses many battery storage operators and grid infrastructure owners.…

Energy-Storage.news | Vopak takes FID on 800MWh Netherlands ‘controllable congestion mitigator’ BESS | Tank storage company Vopak has made a final investment decision (FID) for a 200MW/800MWh battery energy storage system (BESS) project in Oosterhout, Netherlands, following its acquisition of developer Green Energy Storage (GES). The project, with total investments of €230 million (US$262 million), is expected to be operational in H1 2028. Utility Greenchoice will off-take 50% of the capacity under an 8-year tolling agreement. Energy-Storage.news | Alsym Energy signs 9GWh sodium-ion BESS agreement with consultancy for global mining operations | US sodium-ion battery startup Alsym Energy and consulting organization Erity have signed a 9GWh Strategic Relationship Agreement (SRA). This SRA establishes a formal framework for the two companies to jointly identify, pursue, and deliver advanced battery energy storage systems (BESS) for global mining use-cases. The agreement aims to deploy Alsym's non-flammable sodium-ion technology in a sector currently reliant on diesel generators. ESS News | Green Flexibility acquires 3 GWh battery storage portfolio in Germany | Green Flexibility has acquired a portfolio of battery storage projects in Germany from developer Kajoni, totaling 750 MW of power and 3 GWh of storage capacity. The projects are currently advancing through Germany's grid connection maturity process. Kajoni will continue to develop the projects to ready-to-build status, with Green Flexibility providing capital during this phase and then taking over construction, operation, and commercialization.

What Changed This Week

Large-scale battery storage projects reached new operational and financial milestones this week, with Chile and Australia seeing major asset commissioning and funding, while sodium-ion technology advanced towards commercial deployment in the mining sector. Biggest Shift The most significant shift is the commissioning of the 220 MW/1.1 GWh Arena BESS by CIP in Chile and the 300 MWh Bungama BESS by Wärtsilä in South Australia, marking a tangible increase in operational grid-scale storage. These projects move substantial capacity from pipeline to active grid assets, signalling that large standalone storage is now a commercial reality in multiple regions. Company Signals Copenhagen Infrastructure Partners and Wärtsilä both brought major battery projects online, while Alsym Energy secured a 9 GWh strategic agreement with ERITY to deploy sodium-ion BESS in global mining, indicating early commercial traction for alternative chemistries. Vena Energy closed AU$1.4 billion in green financing to accelerate solar-plus-storage buildout in Australia. Grenergy’s 1 TWh PPA for its 3.5 GWh Chilean BESS further demonstrates the maturing of revenue models for storage assets. Grid Signals CAISO, MISO, and PJM advanced market design work on storage participation, with CAISO’s revised straw proposal on outage management and ongoing FERC Order 2222 compliance efforts in MISO and PJM. These regulatory developments could affect how storage is dispatched, compensated, and aggregated, but practical impacts remain pending as stakeholder processes continue. No immediate federal regulatory changes altered the commercial landscape this week. What To Watch Next Monitor the operational performance and market impact of the newly commissioned Chilean and Australian BESS assets, as well as the execution…
