Quinbrook Infrastructure Partners has closed its Quinbrook Renewables Impact Fund II with USD $784 million (£587 million) in commitments, exceeding its USD $668 million (£500 million) target. The fund will invest in renewable energy, battery storage, grid infrastructure, and clean transport across the UK and Ireland, with existing investments including the 373 MW Mallard Pass Solar Project, Aegis Energy, and the 65 MW Project Norton solar-plus-storage development.

KKR and Energy Capital Partners (ECP) have received a deadline extension to July 15 to finalize a takeover offer for Irish energy distributor DCC. The consortium’s revised £ 5.7 billion ($7.6 billion) proposal includes £65.25 in cash per share plus DCC’s proposed final dividend, valuing one of Europe's largest energy distribution platforms. The transaction would mark a major private equity investment in energy infrastructure, highlighting continued investor appetite for established energy transition and distribution assets.

Cloud and data centre operator Aruba has acquired three operational hydroelectric plants in northern Italy, expanding its portfolio to 11 hydro facilities with more than 60 GWh of annual renewable electricity generation. The acquisition supports Aruba's strategy of directly owning renewable energy assets to power its growing data centre operations, complementing existing solar installations at its Rome and Bergamo campuses.

Proxima Fusion, a German fusion energy startup developing commercial stellarator fusion power plants, has raised €411 million ($468 million) in one of Europe’s largest private technology investments of 2026. The company is building next-generation fusion reactors based on stellarator technology, which uses complex magnetic fields generated by high-temperature superconducting magnets to confine plasma and replicate the fusion process that powers the sun. The round, led by XTX Ventures and East X Ventures with strategic investment from RWE and Google, values the company at €2.4 billion ($2.7 billion). The funding will accelerate development of Alpha, Proxima’s net energy fusion demonstrator.

Quaise Energy, a Houston-based geothermal startup, has raised $134 million in the first close of its Series B funding round to develop the world’s first commercial superhot geothermal power plant. The company uses millimetre-wave drilling technology developed from MIT research to ablate rock at depths and temperatures that are not economically accessible using conventional drilling. The technology accesses geothermal resources at temperatures of 300-500 ℃, unlocking a source of constant, carbon-free baseload power. The round was led by Prelude Ventures with strategic investment from JERA and Idemitsu, bringing Quaise’s total funding raised to $230 million. The financing will support Project Obsidian in Oregon, a gigawatt-scale geothermal facility expected to deliver its first electricity to the grid by 2030. 

Axle Energy has raised a USD $25 million Series A led by Energize Capital, with participation from existing investors Accel, Picus Capital, and Eka Ventures. The London-based company develops virtual power plant software that aggregates distributed energy assets including EV chargers and heat pumps to help balance electricity grids. The new capital will support expansion across the UK and international markets, targeting an estimated 75 million eligible energy assets across Europe and the US.

The UK government has approved the 740-MW One Earth Solar Farm, which will become the country’s second-largest solar project and generate enough electricity for more than 200,000 homes. The project, located on the Nottinghamshire and Lincolnshire border, includes a utility-scale photovoltaic system paired with battery energy storage and was originally co-developed by Orsted and PS Renewables. Copenhagen Infrastructure Partners’ Perigus Energy platform is now leading Orsted’s stake following its acquisition of the company’s European onshore renewable business. The approval highlights the UK’s push to accelerate clean energy deployment, with recent planning reforms expected to reduce approval timelines for major infrastructure projects by up to 12 months.
