Orcadian Energy PLC has embarked on a strategic partnership to explore the potential conversion of its Southern North Sea gas fields into a power source for an offshore data centre. The AIM-listed North Sea oil and gas developer announced a non-exclusive joint development agreement with an American offshore data centre developer, prompting a 14% rise in its shares to 19.98p on 2nd September 2026.
The agreement initiates a 90-day period for comprehensive due diligence, commercial validation, and negotiation of a definitive “energy-to-compute” transaction. This period will assess the feasibility of Orcadian’s innovative Earlham Gigagrid concept.
Under the terms, neither party is obligated to sign, finance, or complete a transaction unless separate, definitive agreements are executed. Furthermore, either party retains the right to withdraw from the arrangement with 10 business days’ notice. No financial consideration changed hands upon the signing of the initial agreement.
The undisclosed partner, described as an integrated infrastructure owner and compute operator, focuses on developing offshore computing platforms, owning or financing the necessary hardware, and selling contracted capacity to clients. An option exists for the partner to secure exclusivity until 1st March 2027 for an agreed fee. Should this option be exercised, Orcadian would be prohibited from granting competing rights over its P2680 licence, which includes the Earlham and Orwell fields, and would be required to terminate any rival discussions with third parties.
The core of Orcadian’s strategy is the Earlham Gigagrid concept, first unveiled in July 2026. This plan envisions utilising gas from the Earlham and Orwell fields to fuel an offshore power station, which would incorporate integrated carbon capture technology. This facility is designed to generate approximately 200 megawatts of low-carbon electricity, directly supplying a co-located data centre that would operate independently of the UK national grid.
A key driver for this innovative approach is the high carbon dioxide content of the gas found in the Earlham field, which traditionally renders conventional pipeline export commercially unattractive. By generating power at the field and reinjecting the captured carbon dioxide underground, Orcadian aims to monetise this resource in an environmentally responsible manner.
Steve Brown, Chief Executive of Orcadian Energy, expressed his enthusiasm for the collaboration, stating:
“We are delighted to be working with our new partner to design a scheme using the licence’s gas resources to enable an offshore data centre of real scale in UK waters.”
He further noted that the partner’s “new approach to deploying compute offshore” positions them as a “natural customer for the power the Earlham Gigagrid could generate.”
Mr Brown has previously highlighted that this project aligns with the government’s clean power and energy security goals, enabling a “gigascale data centre” without straining the national grid.
The combined 2C contingent resources for the Earlham and Orwell fields are estimated at 145 billion cubic feet (Bcf) as of 1st January 2026, comprising 114 Bcf at Earlham and 31 Bcf at Orwell.

These figures represent the mid-case estimate of recoverable gas from discovered but undeveloped fields, where commercial recovery is contingent on specific conditions being met.
Orcadian acknowledges that these are internal estimates and plans to commission an independent competent person’s report during the 90-day due diligence period. The company also intends to assess various development scenarios to support the build-out of the offshore compute capacity.
To facilitate the project and attract third-party investment without diluting shareholders’ interests in its other North Sea assets, Orcadian has established a dedicated subsidiary, Earlham Gigagrid Ltd.
