Renewable Energy Weekly — 2026-09-26
This week's headline developments include India's NTPC Green Energy commissioning 68.22 MW of solar in Gujarat and Purvah Green Power signing its first commercial & industrial wind supply deal for a 49.5 MW project in Madhya Pradesh. On the policy front, Ireland's Department of Climate has a busy energy slate in its Autumn 2026 Legislation Programme published 10 September 2026. A new Wood Mackenzie analysis finds that decommissioning and repowering will drive 23% of solar buildout in the 2040s.

Top Stories
Decommissioning will drive 23% of solar buildout in the 2040s, says Wood Mackenzie
- What happened: A new analysis by Wood Mackenzie, published 25 September 2026, projects that decommissioning-related activity — including the full decommissioning of original projects and installation of new modules or turbines on the same site while retaining associated infrastructure — will account for 23% of solar buildout in the 2040s.
- Why it matters: As the first large wave of solar installations ages out, repowering takes center stage as a major growth segment. This opens a new market for developers, EPCs, and recyclers that has barely existed until now.
- Scale: 23% of projected 2040s solar buildout.
Purvah Green Power signs first C&I wind supply deal with Prism Johnson
- What happened: Purvah Green Power has partnered with cement player Prism Johnson to launch a 49.5 MW wind project in Madhya Pradesh, India, signing its first C&I power supply agreement. The deal enhances renewable energy supply for industrial offtakers.
- Why it matters: Corporate/industrial offtake deals are increasingly the financing backbone of new renewable capacity in India, giving wind projects bankable revenue without reliance on state offtake.
- Scale: 49.5 MW, Madhya Pradesh, India.
NTPC Green Energy commissions 68.22 MW solar in Gujarat
- What happened: NTPC Green Energy commissioned 68.22 MW of solar capacity in Gujarat, raising the group's commercial generation capacity from 10,842.86 MW to 10,911.08 MW.
- Why it matters: India's largest state-owned power producer continues steadily building its renewable base, supporting national 500 GW non-fossil capacity ambitions.
- Scale: 68.22 MW added; group commercial capacity now 10,911.08 MW.

Policy & Regulation
- Ireland: The Government's Autumn 2026 Legislation Programme (published 10 September 2026) confirms energy is among the busiest policy areas on the Oireachtas agenda as the Dáil sits through to the Christmas break, with the Department of Climate driving bills forward.
Investment & Finance
- Purvah Green Power: Signed its first commercial & industrial power supply agreement with Prism Johnson for a 49.5 MW wind project in Madhya Pradesh, anchoring industrial demand for new wind capacity.
Technology Spotlight
Electrolyzer market set for rapid expansion to 2035. New market research published this week projects that the global green hydrogen electrolyzers market will expand rapidly through 2035, driven by renewable integration mandates and falling stack costs, with Asia-Pacific leading growth. Separately, the e-batteries market is forecast to grow through 2035 on grid modernization and renewables integration, with demand rising across utility and commercial sectors.
What to Watch Next Week
- Development of the stalled US permitting reform negotiations, where the White House has conditioned advancing wind and solar projects on a deal with Democrats — watch for a response from Congress.
- MERC's proposed regulatory framework supportive of 100 GW renewables in Maharashtra, India — final decisions expected to shape storage procurement.
- Further repowering/decommissioning analysis expected as aging solar assets move into the refresh cycle highlighted by Wood Mackenzie.
