We are an independent energy infrastructure company that owns and operates critical midstream infrastructure, running it safely and efficiently while maximising return for our shareholders. Our business centres around three core themes:

• We nurture and sustain our existing assets and we do this well with the utmost focus on HSE and integrity
• We seek to grow our business through new customers, new investments and new assets
• We want to facilitate change in the energy industry and are building a new business around Net Zero

Dedicated infrastructure owners like Kellas Midstream are fully invested in maximising throughput, delivering high uptime and extending the life of midstream assets.

We are not in competition with upstream operators. Upstream operators are our customers and focusing on their needs is a business imperative.

We seek ways to collaborate not only with our customers, but with our partners and other stakeholders to increase the volume of gas produced in the North Sea, using innovative models that challenge conventional ways of working.

Our history

Our story began in 2014 when Antin Infrastructure Partners invested in the Central Area Transmission System (CATS) via CATS Management Limited, the entity formed to manage Antin's interests in the North Sea. CATS Management set the strategy, delivering safe and efficient operational and financial performance, and growing the business.

Following further investment in the Central and Southern North Sea, and to reflect its growing portfolio, CATS Management rebranded its business to Kellas Midstream.

In only a few years, we have grown significantly – adding the Esmond Transportation System (ETS), and the Humber Gathering System (HGS) to our portfolio; and welcoming new people to our team, whose expertise has added great value to our organisation.

After such success, in early 2020, Antin Infrastructure Partners sold their interest in Kellas Midstream to global investment and asset managers BlackRock and GIC.
