🧭

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.…

ESS News | Aquila secures €26 million financing for German battery project | Aquila Capital, through its subsidiary Aquila Clean Energy, has secured €26 million in fully merchant debt financing from ING Deutschland for a standalone 56 MW/112 MWh Battery Energy Storage System (BESS). The project is located in Wetzen, near Lüneburg in Lower Saxony, Germany. This financing milestone follows the project's construction announcement in November 2024. Energy-Storage.news | CATL to supply 2,400MWh of battery storage for Edify Energy’s Australian hybrid projects | Chinese battery manufacturer CATL will supply 2,400MWh of battery energy storage systems (BESS) to Edify Energy for its Smoky Creek and Guthrie’s Gap Solar Power Stations. These two projects, located approximately 40km north of Biloela in central Queensland, Australia, form a 600MW hybrid solar-plus-storage plant. The plant will feature 720MWp of solar generation and 600MW/2,400MWh of battery storage, with each operating as an independent 300MW unit and connecting to Powerlink’s 275kV network. Energy-Storage.news | New Zealand’s Meridian Energy wins draft approval to access 545GWh of contingent hydro storage | New Zealand state-owned energy company Meridian Energy has received a draft decision proposing to ease access restrictions on contingent hydro storage at Lake Pūkaki in New Zealand’s South Island. This draft approval, effective for a three-year period from winter 2026, covers access to approximately 545GWh of electricity generation capacity. The decision allows Meridian to utilize water stored between 518 and 513 metres above sea level, up to a 4% risk of an electricity shortage as estimated by… Energy-Storage.news | Eku Energy submits 10-hour duration Griffith BESS to Australia’s EPBC Act | Energy storage…

What Changed This Week

Battery storage project financing and commercial agreements advanced on multiple continents this week, with new capital secured for large-scale projects in Germany, Sweden, and the US, and long-term PPAs signed in Malaysia, Chile, and California. These developments point to growing investor confidence in merchant and hybrid storage business models, as well as increasing maturity in offtake structures for battery-backed renewables. Biggest Shift Aquila Capital’s €26 million merchant debt financing for a standalone BESS in Germany and Pathway Power’s $150 million debt raise for a 3.2 GW US portfolio mark a clear shift towards market-based, unsubsidised financing for battery storage. This signals that lenders and developers are increasingly comfortable with merchant risk and the revenue potential of storage assets, especially when paired with renewables. Company Signals Stem expanded its international reach by deploying its PowerTrack EMS at a major hybrid project in Chile, and secured new advisory work in New York, reinforcing its position in both software and services. Multiple developers, including DayOne, Grenergy, and EDF/Masdar, locked in long-term PPAs for hybrid and storage projects, de-risking revenue streams and enabling further buildout. Lightsource bp broke ground on a major solar-plus-storage project in Australia, while Svea Solar Utility and Aquila secured substantial financing for new European projects. Grid Signals Market design work continued in the US, with MISO, CAISO, and PJM all advancing stakeholder processes on DER and storage participation models. MISO’s FERC Order 2222 compliance work and CAISO’s revised storage modeling proposals could reshape how storage and aggregated resources access and operate in wholesale markets.
