Grok: When will the outlook for renewables improve?13 Nov 2025 16:28
The outlook for investing in renewables in the UK is already showing signs of momentum in late 2025, driven by government policy shifts and market dynamics, but significant improvements are projected to accelerate from early 2026 onward as key reforms take effect and economic conditions stabilize.
Current Context and Challenges
As of 2025, the UK renewables sector has achieved notable progress, with renewables contributing over 50% of electricity generation in 2024 and record output levels. However, investors face hurdles like grid congestion (leading to rising constraint costs exceeding £1.8 billion in 2025), supply chain disruptions, high interest rates, planning delays, and policy uncertainties from global events. These have contributed to lean transaction activity, NAV discounts for infrastructure funds (averaging 15-77%), and subdued M&A. Despite this, 72% of investors are accelerating energy transition investments, with 56% focusing on renewables.Short-Term (Late 2025 to Early 2026): The outlook is expected to improve notably in this period due to upcoming grid reforms, such as the shift to a "first ready, first connected" system in spring 2025 and updated connection offers by year-end, which could unlock £200 billion in private investments. Falling interest rates are anticipated to make renewables more attractive relative to bonds, while the government's Clean Power 2030 Action Plan provides policy clarity to boost confidence. The June 2025 Clean Energy Industries Sector Plan, including £700 million for Great British Energy and expansions like the Clean Industry Bonus, is set to catalyze supply chain investments and job growth (e.g., up to 100,000 in offshore wind by 2030). This could mark a pivotal year for smaller funds and M&A revival. Medium-Term (2026-2030): Broader enhancements are forecasted here, with annual investments needing to reach £40 billion (£30 billion for generation, £10 billion for transmission) to meet targets like tripling offshore wind to 43-50 GW and solar to 45-47 GW. Government initiatives, such as CfD scheme reforms for Allocation Round 7, £21.7 billion in CCUS, and battery storage expansion to 24-27 GW, will support this. Renewables' share in the energy mix could rise to 88.5% by 2030, aided by smart grids, AI efficiencies, and reduced regulatory barriers. Longer-Term (Beyond 2030): Sustained growth is projected, with investments doubling to over £30 billion annually by 2035 under the sector plan, aligning with net zero goals and full decarbonisation ambitions. Emerging technologies like hydrogen (targeting 5 GW by 2030) and long-duration storage will further mature. Overall, while challenges persist, the combination of policy support, declining costs, and infrastructure upgrades positions 2026 as a key inflection point for stronger investment returns, potentially leading to a more favourable environment than in recent years.
