BP, Equinor and Ithaca Energy team up on West of Shetland electrification

BP, Ithaca Energy and Equinor are teaming up to slash emissions at huge oilfields in the west of Shetland through electrification.

In an agreement signed today the oil giants will explore electrification options for the region covering the Clair, Rosebank and Cambo fields, each of which are megaprojects by UK standards.

It comes weeks after adjustments to the windfall tax – or Energy Profits Levy (EPL) – granted an effective government subsidy to companies investing in electrification of oil and gas assets.

(Standing) UK energy minister Graham Stuart MP, with (L-R): Equinor SVP for exploration and production Al Cook, BP UK country head Louise Kingham, and Ithaca Energy chairman Gilad Myerson.

Through the agreement, Cambo, Rosebank and Clair are collectively seeking to become some of the first oil and gas developments in the UK to be powered by electricity.

Clean electricity via renewables

Power generation, which typically comes from gas and diesel generators offshore, accounts for around two-thirds of an installation’s emissions, according to the regulator.

Electrification seeks to replace that generation with clean electricity via renewables, although it is costly and technically challenging.

The former boss of Shell’s North Sea business linked the process to “open heart surgery”.

It comes as the industry races to meet emissions-cutting targets – and climate checkpoints for new fields – with the industry needing to slash carbon by 50% by 2030 through the North Sea Transition Deal signed with government in 2020.

For existing assets, electrification is viewed as the only option to meet those goals.

In the memorandum of understanding (MoU), BP, Ithaca and Equinor will assess power from shore – potentially from offshore wind – or an actual offshore wind farm to achieve electrification.

Full electrification would require 200 megawatts of power

The group said the technical and commercial viability of the different hub concepts is to be further developed into early 2023, after which a feasibility study will be carried out to further hone in on a concept.

Full electrification would require in the region of 200 megawatts of power – a fairly modest size compared to the gigawatt-scale ScotWind projects in the pipeline.

Awards are also due out next year for INTOG – a Crown Estate Scotland leasing round specifically for offshore wind farms to power oil and gas assets.

Alongside West of Sheltand, similar plans are in the pipeline for the Central North Sea involving firms including BP, Shell, TotalEnergies and Harbour Energy.

Big projects

New projects such as Equinor’s Rosebank (in which Ithaca is a partner) and Ithaca’s operated Cambo field are being set up with electrification in mind to satisfy the UK regulatory regime.

Both Rosebank and Cambo are due for a key final investment decision next year, together representing two of the largest untapped finds in UK waters at more than 700 million barrels estimated to be recoverable.

The Knarr FPSO, which Equinor intends to modify to support the full electrification of the Rosebank field.

Meanwhile Clair is a huge multi-phase development operated by BP.

The second phase Clair Ridge, expected to recover 640m barrels during the next 40 years, started up in 2018 and a third phase Clair South is in the pipeline.

Signing to kick-start emissions reduction

The deal was signed at a Westminster reception, witnessed by UK energy minister Graham Stuart.

He said: “I am delighted to host the signing of today’s agreement between BP, Equinor and Ithaca to explore the possibilities of electrifying oil and gas production in the UK.

“This signing is an important step for industry towards reducing their emissions, while protecting jobs and delivering on the commitments in the landmark North Sea Transition Deal.”

Government help for electrification

Last month, Chancellor Jeremy Hunt unveiled a hike to the North Sea windfall tax, but kept the general investment allowance the same.

However, there was an increase in the allowance specifically for projects to electrify oil and gas assets – meaning firms spending £100 on decarbonisation will receive £109.25 back.

BP, Equinor and Ithaca said achieving the electrification target will mean overcoming “some commercial regulatory and consenting hurdles.”

Norway’s Equinor, which has electrified projects in its home sector, told Energy Voice this year it hoped the £8 billion Rosebank field will “trigger” wider electrification across West of Shetland.

Drive for lower carbon footprint

A spokesperson for the West of Shetland Electrification (WoSE) group said: “This initiative seeks to evaluate the technical, commercial and regulatory challenges of various low-carbon power hub solutions to recommend a technically and commercially viable option that can meet the requirements of the three field owners within the respective project timeframes.

“Continued production from the West of Shetland supports the UK government’s drive for home-grown oil and gas with a lower carbon footprint while protecting the jobs, skills and supply chain needed to drive the energy transition.”
