Quinbrook invests in the Wexford project
The investment company Quinbrook has entered the Irish energy market. The company acquired Wexford, which operates in the synchronous capacitor sector.
Green Frog Power originally founded the Wexford firm, which provides critical network services, including:
- inertia;
- short-circuit level;
- reactive power.
The Wexford project plays a key role in stabilizing the Irish power system. Its design capacity is 963 MVA. In 2024, the company won a tender to provide Low-Carbon Inertia Services (LCIS) and signed a long-term contract that guarantees stable income. The facility is scheduled to launch in 2027. These factors have enhanced the project’s investment attractiveness and attracted Quinbrook’s attention.
Quinbrook representative Keith Gaines emphasized the importance of investing in the Irish energy sector. Ireland is steadily moving toward its goal of obtaining 80% of its electricity from renewable sources by 2030. Maintaining grid stability is necessary to achieve this goal, as the grid must be able to withstand the transition to green energy.
The partnership with Quinbrook is valuable to Wexford not only in terms of financial support. The investment company has experience managing energy assets.
The potential of synchronous condensers
Synchronous capacitors are designed to ensure grid stability. They maintain system inertia and reduce the risk of power outages. Similar to standard generators, capacitors create a stabilizing effect. This allows for greater use of renewable energy without endangering the grid.
Quinbrook plans to actively develop the project, which is currently under construction. The company is financing the construction of the facility. It will oversee the work through its partner, Welsh Power. Welsh Power participated in installing a number of Quinbrook capacitors in the UK. Welsh Power has in-depth knowledge and experience in creating complex network infrastructure.
About the company
Notably, Quinbrook is the largest private owner of synchronous capacitors in the UK. The company has invested over US$572 million in this area.
In early 2025, Quinbrook received financing from Deutsche Bank for battery construction. The investment amounted to US$505.4 million. This project is one of the largest in Australia’s BESS sector.
Deutsche Bank took on the roles of organizer and initial lender. Quinbrook is managing all construction processes. The company plans to expand the project in the future, which will increase the facility’s initial capacity.
