IHA’s Delhi Declaration calls for policy overhaul to unlock India’s 288GW pumped…

The International Hydropower Association released the Delhi Declaration, outlining five policy priorities to unlock India’s estimated 288 GW of pumped‑hydro energy storage (PHES) potential. It urges faster project clearances, stronger revenue mechanisms, and tighter coordination between central and state bodies to meet the 100 GW PHES target by 2035‑36. The declaration calls for parallel approval processes, single‑window clearances, dedicated development zones, and market reforms that compensate PHES for ancillary services. It aligns with the Central Electricity Authority’s roadmap and the growing storage demand driven by expanding renewables.

💡 By streamlining approvals and securing revenue, the declaration could transform India’s grid flexibility and energy security, positioning PHES as a cornerstone of the country’s renewable integration strategy.

Solar Energy Industries Association to Combine with Coalition for Community Solar Access,…

The Solar Energy Industries Association (SEIA) and the Coalition for Community Solar Access (CCSA) announced their merger, effective early October, after board approvals. CCSA’s team, resources, and policy work will be integrated into SEIA, creating the sole national trade association covering all solar and storage segments—utility‑scale, commercial, residential, and community. The combined entity will strengthen advocacy at state and federal levels, leveraging SEIA’s long‑standing influence and CCSA’s recent growth in community solar. The merger aims to unify the industry’s voice and accelerate market expansion.

💡 By consolidating the two largest trade groups, the merger eliminates fragmented lobbying, enabling a single, coordinated push for policies that support the rapid growth of solar and storage across the U.S.

Sierra Club Strongly Opposes Bill to Give Legal Immunity to Fossil Fuel…

The U.S. House Judiciary Committee is set to markup H.R. 8330, a bill that would grant fossil‑fuel companies blanket legal immunity from lawsuits related to climate change and associated disasters. The Sierra Club, citing the industry’s awareness of climate impacts since the 1950s and a study projecting U.S. climate costs to exceed $1 trillion this year, issued a coordinated statement condemning the proposal. Representatives from the Club’s national office and state chapters in Vermont, Colorado, California, and Texas warned that the legislation would shift cleanup costs onto taxpayers while protecting corporate donors. The Committee’s action follows similar immunity bills passed in Republican‑led states, including Utah’s recent enactment, and comes amid ongoing cuts to disaster relief and climate‑resilience funding.

💡 By insulating Big Oil from liability, the bill could lock billions of taxpayer dollars into climate recovery, undermining accountability for decades‑long emissions.

Inside the effort to make data centers pay their share of electricity…

A Straight Arrow News investigation examined the murky responsibility for funding new power infrastructure when data centers locate in a community. The report, published by the Center on Global Energy Policy, found that local utilities, developers and municipalities often negotiate ad‑hoc agreements, leaving taxpayers to shoulder a disproportionate share of the costs. The study highlighted several Texas projects where utilities upgraded transmission lines and substations without securing full reimbursement from the operators, prompting public‑hearing disputes and legal challenges. It also noted that many planned facilities are stalled or cancelled due to financing pull‑backs, underscoring the volatility of the AI‑driven data‑center boom. The investigation calls for clearer policy frameworks to allocate electricity‑related expenses more transparently and equitably.

💡 Without standardized cost‑allocation rules, communities risk bearing hidden infrastructure bills while the promised economic benefits of data centers remain uncertain.

Al Gore has a surprisingly calm take on the AI data center…

Al Gore, a longtime climate advocate, told TechCrunch that emissions from AI data centers are less alarming than other environmental issues. He noted that the combined emissions of AI facilities are only a fraction of those from uncovered landfills and far lower than global air‑conditioning demand, which the International Energy Agency says already uses more electricity than the European Union and could triple by 2050. Gore warned that some hyperscalers are adopting methane‑fueled turbines, risking decades of fossil‑fuel lock‑in, and urged a shift toward renewables and batteries, which are becoming the cheapest option. He also argued that public opposition to data‑center projects stems more from fears of automation‑driven job loss than from carbon concerns, echoing warnings from AI insiders today.

💡 Gore’s framing shifts the debate from carbon footprints to the socioeconomic fallout of AI, urging policymakers to prioritize renewable power and job‑security strategies.

‘Sodium-ion still very much on the fringe’: German market sources on technology…

At the Energy Storage Summit Germany 2026, panelists confirmed lithium‑iron‑phosphate (LFP) batteries remain the preferred chemistry for German battery energy storage systems (BESS). Sodium‑ion technology is still considered fringe and not bankable, with investors and developers citing risk aversion. Discussions highlighted challenges in power‑conversion systems, state‑of‑charge accuracy, and balancing, while noting emerging revenue opportunities from inertia and grid‑forming services. Certification gaps and EU policy shifts on Chinese equipment add further uncertainty to procurement decisions.

💡 The debate underscores a critical bottleneck in scaling BESS: without proven, bankable alternatives to LFP, Germany’s ability to meet grid‑stabilisation targets and diversify supply chains remains constrained.
