What Kellas Midstream does
Kellas Midstream is a UK-based, independent energy infrastructure company that develops, owns and operates midstream gas transportation and processing assets in the Central and Southern North Sea. Its three core systems are the Central Area Transmission System (CATS), a 396 km pipeline and Teesside terminal that delivered 7.3 billion cubic metres of gas to UK markets in 2024 and serves over 30 producing fields; the Esmond Transportation System (ETS), a 165 km pipeline delivering gas to the Perenco-operated Bacton terminal in Norfolk; and the Humber Gathering System (HGS), a 48 km pipeline and platform with 300 million standard cubic feet per day nominal capacity that delivers gas from the Tolmount fields to the Easington terminal in Yorkshire. Approximately 40% of UK natural gas production flows through the company's pipelines and is processed at its onshore facilities.
The business model is tariff-based midstream infrastructure: Kellas charges producers for gas transportation and processing services via long-term contracts and joint venture structures in which it typically also holds equity in the underlying fields or pipelines (e.g., 65% of ETS, 50% of HGS, 98.9982% of CATS). The company is majority owned by BlackRock and GIC, with Harbour Energy and ENI holding minor equity in CATS, Ithaca Energy and Harbour holding ETS interests, and Dana Petroleum as the 50/50 HGS infrastructure partner. Day-to-day operations are run through operating partners Wood (CATS) and ODE Asset Management (HGS).
The company is actively extending its asset base beyond gas transport into the energy transition, primarily through H2NorthEast, a Nationally Significant Infrastructure Project on Teesside for blue hydrogen production in partnership with SSE, with additional exploration of green hydrogen and CCS adjacent to its existing footprint.

Kellas Midstream product offering
Product offeringCore offering
Kellas Midstream develops, owns, operates, and invests in midstream gas transportation and processing infrastructure in the UK's Central and Southern North Sea. The company delivers natural gas from offshore producing fields to onshore reception terminals and into the UK National Transmission System through three pipeline systems (CATS, ETS, HGS), and is developing the H2NorthEast blue hydrogen project on Teesside.
Product overview
Kellas Midstream is an independent energy infrastructure company that develops, owns, and operates critical midstream infrastructure in the Central and Southern North Sea. The company's portfolio consists of three core gas transportation and processing systems: CATS (Central Area Transmission System) for the Central North Sea, ETS (Esmond Transportation System) for the Southern North Sea, and HGS (Humber Gathering System) as their newest infrastructure. Additionally, the company is developing H2NorthEast, a blue hydrogen project classified as Nationally Significant Infrastructure. Around 40% of the UK's natural gas production is transported through their pipelines and processed at their onshore facilities.

Kellas Midstream competitors and assessment
Company assessmentBroad incumbents
- Williams Companies: US-based large-scale natural gas pipeline and midstream operator. Comparable as a broad incumbent in pipeline transportation, though operating in North America rather than the UK North Sea.
- National Grid: Operates the UK National Transmission System (NTS) that receives all of Kellas Midstream's gas deliveries. Comparable as the dominant regulated UK gas transmission infrastructure operator, though at much larger scale and broader scope than Kellas's upstream-focused North Sea pipelines.
- Enbridge: Major North American midstream operator with significant natural gas pipeline, processing, and terminal infrastructure. Comparable as a broad incumbent in scaled midstream asset ownership and operations.
Regional players
- Neptune Energy: Operates producing North Sea fields that feed midstream gas infrastructure, including facilities in adjacent basins. Comparable as a regional North Sea gas operator with similar customer profile and dependency on offshore gathering systems.
Direct peers
- Dana Petroleum: 50/50 JV partner in HGS infrastructure and 50/50 partner in upstream Tolmount gas reserves. Directly comparable as a North Sea operator co-developing midstream infrastructure with Kellas on the Southern North Sea.
- Ithaca Energy: Operates the Cygnus field (delivering 5% of UK gas via ETS), holds 25% equity in ETS, and serves as statutory operator for ETS. Directly comparable as a North Sea operator with embedded infrastructure interests in Kellas's systems.
- Perenco UK: Operates the Bacton terminal where Kellas's ETS pipeline delivers gas and also operates the Trent field connected to ETS. Directly comparable as a UK North Sea midstream operator and gas terminal owner with overlapping customer relationships.
- ENI UK: Holds 0.3388% equity in CATS North Sea Limited as a minority partner. Comparable as a North Sea E&P with integrated infrastructure interests and historical exposure to CATS.
- Harbour Energy: Largest UK North Sea producer, operates the CATS riser platform, holds 0.6630% equity in CATS, and is upstream JV partner on Tolmount. Comparable as a major North Sea gas operator deeply integrated with Kellas's CATS and ETS systems.
Others
- Wood Group: Long-term operating partner for the CATS terminal and pipeline, providing day-to-day operational resources under a strategic relationship model. Comparable as the contracted operator executing Kellas's midstream service delivery.
