O&M contracts for Octopus Energy Generation

by RES | Aug 16, 2022 | Reading time: 2 min

RES, the world’s largest independent renewable energy company, has migrated over 50 operation and maintenance (O&M) contracts to long-term agreements. This follows a period of successful delivery and collaboration with the fund management team within Octopus Energy Generation, who are one of Europe’s largest investors in renewable energy. In total RES will now deliver services for 60 solar farms in this portfolio sized at 385MW, located in the UK.

As part of the long-term contracts, RES will manage High Voltage services in-house, in addition to providing an enhanced spare parts management service and standalone ‘specialist inverter defect rectification services’ on several solar farms in the non-RES part of the Octopus portfolio.


RES now provides O&M services on nearly half of Octopus’ UK solar portfolio and has helped further improve the performance of the portfolio since the partnership began.


In addition, RES has rolled out a programme of cyber security upgrades and reliability engineering studies. RES is also supporting Octopus with their Environmental, Social and Governance (ESG) goals around biodiversity in particular, including the facilitation around the delivery of a programme of biodiversity studies and subsequent biodiversity enhancements.

RES will deploy the broad range of skills and expertise developed over 40 years of operations to add further value to this portfolio.


Brian Darnell, Head of Solar & Storage O&M, UK&I at RES, said: “We’ve been working with the Octopus team for a number of years now and we’re delighted that we are nearing completion of migration to long-term contracts, which is testament to the partnership we have built.


“Our expertise in O&M means we can confidently continue delivering safety and innovation in equal measure as we embed the 60 solar farms into our portfolio. We have built a relationship of trust and being appointed as O&M contractor on a significant proportion of the UK Octopus solar portfolio is something we are incredibly proud of.”

RES works to maximise the value of assets, and its O&M services includes performance analysis, enhanced spare parts management, cyber security upgrades, HV services, ESG improvements, engineering studies, inverter repowering and much more.
