Today’s renewable energy news includes announcements on Thor offshore substation in Denmark, Haesong’s grid interconnection agreement, Copenhagen Energy, CIP Partner, among others.
Thor Offshore Substation Ready for Sail-Away to Denmark
The 1 GW Thor offshore substation has completed fabrication at the Smulders–Lamprell yard in the Netherlands and is now set for sail-away aboard Heerema’s Thialf semi-submersible heavy-lift vessel. The 3,500-tonne steel jacket and 2,800-tonne topside were fully assembled and pre-commissioned onshore, including FAT of the 220 kV AC switchgear and transformers supplied by Fuji Electric. Sea fastening and marine surveys were completed in June 2025, with the convoy expected to depart Rotterdam in July and arrive at the Anholt deployment site off Denmark’s east coast in August. Installation by Heerema’s Svanen crane vessel will follow, with hook-up and commissioning scheduled for Q4 2025. The turnkey contract awarded to an Energinet–Orsted consortium covers design, transport, installation, and grid testing. Once operational, the substation will export up to 1 GW of wind power via dual export cables to the Danish transmission network.
Haesong Project Secures Grid Interconnection Agreement
The Haesong offshore wind project — developed by a consortium led by Hanwha Ocean and Green Energy Partners — has signed a 20-year grid interconnection agreement with Korea Power Exchange (KPX) to export up to 1 GW via a new 220 kV cable to the Tongyeong substation. Under the deal, the developer will fund all onshore transmission works — including 25 km of buried export cable, high-voltage switchgear, and substation upgrades — while KPX conducts final grid studies and assigns firm capacity. The agreement follows completion of environmental approvals and public consultations, with construction due to start in 2026 and commissioning targeted for Q4 2028. The project’s €2 billion CAPEX covers turbine procurement, foundations, and grid works, financed through a mix of equity and project debt. Once operational, Haesong will supply secured renewable power under long-term offtake contracts to Korean utilities, helping meet national green energy mandates.
Copenhagen Energy and CIP Partner on 100 MW Solar + 50 MWh Storage Project in Denmark
Copenhagen Energy and Copenhagen Infrastructure Partners (CIP) have formed a 60:40 joint venture to develop a 100 MW ground-mounted solar PV array alongside a 50 MWh lithium-ion battery energy storage system at the Havelsee site near Fredericia, Denmark. The €80 million project, now in detailed engineering following final permit approval in June 2025, will occupy 120 hectares of former agricultural land. Construction under an EPC contract with European Solar Solutions will start in Q1 2026, with mechanical completion targeted for Q3 2026 and full commercial operation by year-end. A 10-year corporate PPA with Ørsted covers 50 MW of solar output, while grid-balancing and frequency containment reserve services will be sold to Energinet under a grid-use agreement. Siemens Gamesa will provide a 15-year O&M package, including remote monitoring and predictive maintenance. Job creation during construction is estimated at 150 FTE years, alongside a €200,000 community fund. The hybrid plant is expected to deliver daily peak-shifting and reduce solar curtailment by up to 20 percent, supporting Denmark’s target of 100 percent renewable electricity by 2030.
