Three companies operating across renewable energy consultancy, energy management, and offshore solutions have joined forces to target the growing South Korean offshore wind operations and maintenance market, signing a memorandum of understanding to provide balance of plant services under a unified delivery structure.

The Alliance and Its Structure

Renewable energy consultancy OWC, Korea Leading Energy Management (KLEM), and OEG have entered into a tripartite memorandum of understanding to collaborate on offshore wind balance of plant operations and maintenance services in South Korea.

The agreement was signed in Seoul, South Korea, and brings together three organisations with distinct but complementary capabilities to serve offshore wind asset owners operating in the country.

Under the terms of the collaborative framework, KLEM is expected to act as the main contractor for balance of plant operations and maintenance services. OWC will provide technical assurance and asset management services, while OEG will contribute marine, subsea, and offshore operational services.

The arrangement is designed to present offshore wind farm operators with a single-team approach to the full range of balance of plant operations and maintenance requirements.

What Each Partner Brings

OWC is a renewable energy consultancy that supports clients in de-risking and developing grid-scale renewable energy projects globally through independent engineering, project development, technical engineering, environmental planning, and asset management services.

It operates as one of four brands under ABL Group ASA, a publicly listed company on the Oslo Stock Exchange that has offices in 39 countries worldwide and describes itself as a leading independent global consultancy delivering energy, marine, engineering, and digital solutions.

KLEM is an energy solutions company that offers consulting, engineering, installation, and operations and maintenance services for renewable energy projects across South Korea.

The company's chief executive, Boo Jeonghwan, described the ambition of the partnership as providing offshore wind developers and asset owners with a comprehensive solution for the inspection, maintenance, integrity management, and lifecycle support of balance of plant assets.

OEG describes itself as a leading energy solutions business providing mission-critical infrastructure assets and technical solutions to the global offshore energy industry.

David Carr, Chief Commercial Officer at OEG, noted that the offshore environment presents unique challenges for the inspection and maintenance of balance of plant assets, and that operating as one team with KLEM and OWC would help asset owners gain a more complete understanding of asset condition.

The Strategic Rationale

The formation of the alliance is tied directly to South Korea's stated offshore wind ambitions. According to Will Cleverly, CEO of OWC, South Korea has set a target of 25 gigawatts of offshore wind capacity by 2035.

Cleverly pointed to the increasing pressure that asset owners will face as more projects move from development into the operational phase, highlighting the need to maintain asset reliability, maximise operational performance, and protect long-term asset value.

Cleverly said the combination of OWC's technical assurance expertise, KLEM's operational delivery capabilities, and OEG's specialist marine and subsea capabilities would offer owners a single, integrated approach to balance of plant operations and maintenance.

He described the partnership as creating a strong foundation for informed asset management decisions and said it would support the optimisation of performance, integrity, and lifecycle value of Korean offshore wind infrastructure.

Boo Jeonghwan of KLEM echoed that framing, stating that combining complementary expertise across operations, engineering, technical assurance, and marine services would enable a more integrated approach to supporting the long-term reliability and performance of balance-of-plant assets. Carr from OEG said the alliance would strengthen integrity management programmes and support safe, efficient operations throughout the asset lifecycle.

Focus on Balance of Plant Operations

Balance of plant refers to the components of an offshore wind farm beyond the turbines themselves, including subsea cables, foundations, offshore substations, and inter-array cabling.

These assets require specialist inspection, maintenance, and integrity management services throughout the operational life of a project, and managing them effectively is widely regarded as critical to the commercial performance of offshore wind investments.

The tripartite structure of the alliance is specifically designed to address the full scope of these requirements, with each partner contributing services that the others do not provide independently.

By positioning as a single team, the three companies are seeking to reduce the coordination burden on asset owners who would otherwise need to manage separate contracting relationships across technical, marine, and operational disciplines.

Market Context

South Korea's offshore wind sector is at a pivotal stage of development, with the government's 25 gigawatt target for 2035 underpinning a significant pipeline of projects that are expected to progress from construction into long-term operations over the coming years. As those projects enter service, demand for professional operations and maintenance services is expected to grow substantially.

The Seoul signing ceremony was attended by Boo Jeonghwan of KLEM, Will Cleverly of OWC, and David Carr of OEG, and the announcement was published on 16 July 2026. Further information on the partnership is available through OWC's team in Korea.

Powering Your Pipeline: Stay Ahead of South Korea's Energy Boom

South Korea's power sector is expanding at a pace few industries can match; new generation capacity, grid modernisation drives, and renewable energy mandates are reshaping the competitive landscape almost daily. If your business development strategy still relies on fragmented sources and delayed intelligence, you are already behind the curve.

Winning in this market requires more than awareness of headline projects. It demands a structured, reliable view of the entire project lifecycle, from early-stage planning through to completion. That is precisely what the Global Project Tracking (GPT) platform by Blackridge Research is built to deliver across the South Korean power sector.

Whether you are a contractor, equipment supplier, financier, or consultant, the platform gives you the project intelligence needed to allocate resources with confidence, engage clients at the right moment, and benchmark activity across markets.
