GlobalData’s latest report, ‘Switzerland Power Market Trends and Analysis by Capacity, Generation, Transmission, Distribution, Regulations, Key Players and Forecast to 2035’, provides a comprehensive assessment of Switzerland’s power sector. The report examines installed capacity (GW), electricity generation (TWh), technology shares, and policy developments across the historical period (2020–2024) and forecast period (2025–2035). It also analyses market drivers, restraints, investment opportunities, and profiles of leading companies. The research draws on GlobalData’s proprietary databases, primary and secondary research, and in-house analysis.
Switzerland is advancing its clean energy transition, supported by strong large hydropower and pumped storage dominance, solar PV expansion, and policies aimed at achieving net-zero emissions by 2050. Nuclear power is planned to be phased out gradually, while large hydropower and pumped storage remains the backbone of the electricity mix, accounting for more than half of total generation. Against this backdrop, Switzerland’s renewable power generation is forecast to reach 31.4TWh in 2035, up from 11.4TWh in 2024, registering a CAGR of 9.7% during 2024–2035.
The report reveals that large hydropower and pumped storage will continue to dominate the generation, while solar PV emerges as the fastest-growing segment. Solar capacity is projected to rise from 8.2GW in 2024 to 32.1GW in 2035, supported by mandatory rooftop PV installation requirements, alpine solar initiatives, and subsidy schemes such as the Solar Express Program.
Switzerland’s energy system is shaped by seasonal challenges. While hydropower and solar dominate in summer, supply security in winter is supported through pumped storage, electricity imports, and alpine solar initiatives. Federal measures, including the revised Electricity Act 2025 and the Federal Act on a Secure Electricity Supply with Renewable Energies, are providing strong policy backing for renewables.
The nuclear phase-out under the Energy Strategy 2050 is gradually reducing baseload capacity, with all new nuclear projects banned since 2018. However, the government continues to debate the long-term role of nuclear amid supply security concerns. Meanwhile, green hydrogen and Power-to-X projects are being explored to enhance seasonal storage and diversify supply.
Looking ahead, Switzerland faces challenges from grid congestion, winter supply gaps, and limited land availability for utility-scale renewables. At the same time, opportunities are growing in cross-border electricity trading, alpine solar deployment, and green hydrogen development. Switzerland’s reliance on hydropower, combined with ambitious solar expansion and storage initiatives, provides a strong foundation for its clean energy transition. With targeted policies and growing investment in solar, hydrogen, and interconnections, the country is positioned to balance seasonal challenges and achieve its net-zero target by 2050.
