InfraStrata, through its subsidiary, Islandmagee Energy Limited, has signed a binding term sheet with Vitol to enter into a Gas Storage Agreement for long-term storage capacity offtake at the company’s proposed gas storage facility in Islandmagee, Northern Ireland.

Under the Term Sheet, Vitol will, on an exclusive basis and subject to conditions precedent and final agreement, enter into a 12-year Gas Storage Agreement (GSA) with Islandmagee Energy Limited to utilise the capacity of all seven gas storage caverns proposed at the facility, totalling 500mcm. 

Having now underpinned the facility’s future revenue stream, subject to execution of the GSA, the company will continue to focus on completing discussions and agreeing terms with EPC contractors and potential equity and debt partners to provide funding at the project level to enable FID (final investment decision) for construction of the facility. 

As per the company’s announcement on May 9, 2019, the Term Sheet for seven caverns means that FID for Phase 2 (caverns 3 to 7) will be advanced by approximately 12 months from Q4 2020 to Q4 2019, with the knock-on effect that FID for Phase 1 (caverns 1 &2) is expected to also be taken in Q4 2019.

Construction of the caverns is planned to commence in late 2019 (subject to funding) and first gas is then expected to be injected under the GSA in the fourth quarter of 2022, with full commercial operations planned to commence in storage year 2023-24 (which runs from April 1 each year).

The storage capacity charge that has been agreed between Vitol and InfraStrata will incorporate a multi-layer optimisation structure absorbing the intrinsic and extrinsic pricing elements of the UK gas markets that are available to a storage operator. 

In addition, given the high-performance characteristics of the facility, it will be able to capture significant incremental value generated by sudden movement events (SUMO Events) as well as to help balance the overall UK gas network. SUMO Events typically occur during periods of high volatility, when the gas networks are stressed either by over- or under-supplies relative to demand.

InfraStrata has carried out extensive modelling work over the past few months which indicates that had the facility been in operation for the past ten years, the effective storage capacity charge would have averaged in the region of 28-38 pence per therm annually as the storage operator’s (currently Islandmagee Energy Limited) share of the overall revenues. 

Once the entire working volume of 500mcm is made available to Vitol, this would translate into projected annual revenues of between £50 million and £65 million at project level before operating, maintenance and other costs. This level of a storage capacity fee structure is in keeping with InfraStrata’s expectations of its brand new, state-of-the-art fast cycle facility.

The Term Sheet has an initial term of 12 months and thereafter can be extended for successive periods of 6 months by written agreement between both parties.
