Policy & Regulation
- India: The power ministry has sent the draft National Electricity Policy 2026 to Cabinet; it seeks to improve the financial viability of the power sector, ensure reliable and quality supply, and meet peak demand and energy requirements
- Ireland: A €600 grant for household solar battery storage is set to be announced in the country's budget, paid in addition to the existing SEAI support and designed to cut homes' fossil fuel dependence
- India (Gujarat): An S&P Global analysis says Gujarat is emerging as a key green hydrogen hub thanks to its refinery and ammonia capacity and strong renewable resources, though large-scale projects remain at feasibility stage as India targets three million tonnes of green hydrogen
Investment & Finance
- Raudsepa storage, Estonia: Taaleri Energia and KJK Capital agreed to back a 192 MW/420 MWh battery project due online in November 2027
- Global investment flows: A new analysis finds renewable energy capital is shifting beyond simply building more solar farms and wind projects, with solar, storage and grid infrastructure increasingly attracting the multi-hundred-billion-dollar flows
Technology Spotlight
Repowering to reshape solar's next decade: Wood Mackenzie analysis published today says decommissioning and repowering — replacing modules or turbines on existing sites while retaining grid and site infrastructure — will drive 23% of solar buildout in the 2040s. The finding signals a shift from greenfield expansion to lifecycle optimization as the first big cohorts of PV projects age out.
What to Watch Next Week
- India's Union Budget processes could formally confirm the €600 solar battery grant once announced in Ireland — watch for the Irish budget details on grant administration via SEAI
- India's Cabinet decision on the draft National Electricity Policy 2026, which covers power sector viability and peak demand readiness
- Further updates on the Raudsepa project financing structure as Taaleri and KJK detail their investment terms ahead of the November 2027 online date
