NSTA granted urgent powers to approve North Sea tiebacks ahead of new legislation

The North Sea Transition Authority has been granted new powers to approve urgent licensing cases for North Sea projects before the relevant legislation is formally enacted. This regulatory change allows the body to issue transitional energy certificates, or TECs, for specific tieback projects that meet strict criteria, even though the broader legal framework has not yet passed through Parliament. The move is intended to accelerate the development of existing infrastructure and support the UK’s energy security objectives without waiting for the full legislative process to conclude.

North Sea Transition Authority chief executive Stuart Payne confirmed that the regulator is currently tracking 15 additional projects that are awaiting government and regulatory sign-off. These projects represent approximately ten billion pounds in new capital investment. While the Jackdaw field has recently received approval, Payne indicated that the Rosebank project, which is the UK’s largest untapped oilfield, may not be the next to receive government sign-off. He stated that the timeline for Rosebank will be governed by the environmental assessment process currently being undertaken with the Office for Pollution Prevention and Reduction. The duration of this process will determine when a decision can be made, regardless of the new urgent powers.

The new powers were announced alongside the government’s approval of Adura’s Jackdaw field, which is a tieback to the existing Shearwater Hub. The measure serves as a precursor to the shift from traditional licensing rounds to the transitional energy certificates announced in last year’s budget. Industry participants have waited nearly a year for specific details on which projects would be eligible for a TEC, beyond the previous vague definition of tiebacks. Payne explained that the government recognised that legislation takes time to pass, and in the interim, there may be urgent opportunities suitable for a TEC that cannot be awarded until the law is in place. Consequently, the NSTA can now award a TEC-like licence to address these immediate needs.

To qualify for a TEC under these new urgent powers, projects must meet three specific criteria. First, the project must be literally adjacent to an existing licence block and capable of being connected via a tieback. Second, the tieback must extend the economic life of the existing facility. Third, the applicant must provide compelling proof that the project is ready to invest and act immediately, demonstrating technical, economic, and physical capability. The crucial element is urgency, requiring evidence that the project cannot wait for the standard legislative timeline. Payne emphasised that the regulator is treating each case on its own merits while striving to make decisions as quickly as possible.

Adura chief executive McCulloch noted that his company is not set to apply for further North Sea acreage in the near term, as projects like Rosebank already hold licences. However, he described the new powers as a positive move for other operators who can now proceed with activities to stimulate the supply chain and direct energy into the UK. The original concept for TECs originated from a recommendation by Professor John Underhill of Aberdeen University, who proposed infrastructure-led permits to enable the drilling and tie-back of prospects near strategic infrastructure. Underhill later stated that his original proposal was more ambitious than the government’s current interpretation, which focuses on discoveries in areas adjacent to existing licences to keep fields economically viable while preventing exploration in new unlicensed areas.
