Sustainability Partners, a U.S.-based company specialising in sustainable infrastructure, has been appointed to manage the operations of Ecofin U.S. Renewables Infrastructure Trust PLC, a London Stock Exchange-listed investment company. The appointment was announced on May 15 by Sustainability Partners, confirming that the mandate includes the daily supervision of Ecofin’s energy assets portfolio across the United States.
The portfolio consists of utility-scale renewable energy projects secured by fixed-price Power Purchase Agreements (PPAs) with electricity companies rated as investment-grade. Sustainability Partners’ responsibilities include overseeing operations and maintenance providers as well as coordinating with third-party asset managers.
A portfolio spanning Texas and California
The assets include the Whirlwind wind farm located in Texas, with a capacity of 59.8 MW and comprising 26 turbines. In California, two solar projects – Beacon II and Beacon V – offer a combined capacity of 107.8 MWdc. These facilities form the Beacon Portfolio and deliver energy under long-term contracts.
The aim is to ensure consistent operation and optimal performance as per the terms of the mandate. The financial terms of the agreement have not been disclosed by either party.
A strategy focused on sustainable infrastructure management
Sustainability Partners operates under a service-based model involving monthly leasing of infrastructure assets, without requiring upfront capital investment from clients. This approach is designed to meet the needs of public and semi-public entities such as municipalities and hospitals, while ensuring continuous maintenance of deployed infrastructure.
“This partnership with RNEW confirms our commitment to maintaining large-scale energy assets that are both reliable and high-performing,” said John Veech, Chief Executive Officer of Sustainability Partners.
