Centrica Enters Into Long Term Natural Gas Sale & Purchase Agreement

The title of this post, is the same as this press release from Centrica.

This is the sub-heading,

Centrica plc today confirmed that its trading arm, Centrica Energy, has entered into a natural gas sale and purchase agreement with US-based Devon Energy Corporation.

This first paragraph adds a few more details.

Under the agreement, Devon Energy will supply 50,000 (MMBtu) per day of natural gas over a 10‑year term starting in 2028. This is equivalent to five LNG cargoes per year. The volumes will be indexed to European gas hub price (TTF). This sale and purchase agreement supports Centrica’s objective of managing market price risk in its LNG portfolio by aligning feed gas pricing with European gas prices whilst providing Devon Energy with international price exposure.

At a first look, it looks a lot of gas.

In Investment In Grain LNG, I talk about Centrica’s purchase of the Grain LNG Terminal from National Grid. But the Grain LNG Terminal comes with several things that Centrica might need for gas from Devon.

• A large amount of gas storage.
• The ability to convert liquid natural gas (LNG) into gas suitable for consumers.
• Space to build more storage if required.
• The ability to store LNG for other companies.
• Two jetties for delivering the LNG to the Grain LNG Terminal.
• The ability to load tankers with LNG, so that it can be sold on to third parties like say the Germans or the Poles.

Centrica also say this about their use of the Grain LNG Terminal in this press release, that describes the purchase of the terminal.

Aligned with Centrica’s strategy of investing in regulated and contracted assets supporting the energy transition, delivering predictable long-term, inflation-linked cash flows, with 100% of capacity contracted until 2029, >70% until 2038 and >50% until 2045.

Centrica have obviously modelled their gas supply and delivery and I believe they have come up with a simple strategy, that will work.

How Will Centrica Use The Gas From The Grain LNG Terminal?

The Wikipedia entry for the Grain LNG Terminal says this about the terminal delivering gas into the gas grid.

The terminal can handle up to 15 million tonnes per annum of LNG, has a storage capacity for one million cubic metres of LNG, and is able to regasify up to 645 GWh per day (58 million cubic metres per day) for delivery into the high pressure gas National Transmission System (NTS).

Note.

1. This will be one of the major uses of the gas.
2. I wouldn’t be surprised if these capacities will be increased significantly, so that more gas can be stored and processed.

In Investment in Grain LNG, I outlined how I believe that hydrogen and ammonia will be produced for the bunkering of ships on one of busiest sea lanes in Europe, if not the world.

Some LNG will be used to create these zero-carbon fuels.

Some modern ships, also run on natural gas, so I asked Google AI about their operation and received this answer.

Ships can run on natural gas, specifically liquefied natural gas (LNG), by using it as a fuel source in specially designed engines. LNG is natural gas that has been cooled to a liquid state at -162°C, making it easier to store and transport. This liquid form is then used to power the ship’s engines, either directly or by burning the boil-off gas (BOG) that naturally occurs when LNG warms up.

This means that some LNG could be used to directly fuel these ships.

What Is The Gas Capacity Of The Grain LNG Terminal?

I asked Google AI this question and received this answer.

The Grain LNG Terminal, the largest LNG import terminal in Europe, has a storage capacity of 1,000,000 cubic meters (m³) and an annual throughput capacity of 15 million tonnes of LNG. This is equivalent to about 20% of the UK’s total gas demand. The terminal also has the capacity to deliver 25% of the UK’s daily gas demand.

As the space is there, I wouldn’t be surprised to see Centrica increase the capacity of the terminal, as in cold weather, emergency gas for Germany can be delivered quicker from Kent than the United States.

Could The Grain LNG Terminal Accept Gas Deliveries From The United States?

I’m certain that it already does.

Could The Grain LNG Terminal Accept Gas Deliveries From The UK?

If we start extracting gas again from under the seas around the UK, could the Grain LNG Terminal be used to store it?

Yes, but it would have to be liquified first.

It would be more energy efficient to process the extracted gas, so it could be used directly and gasify enough gas at Grain LNG Terminal from storage to make up any shortfall.

Conclusion

Centrica have done some very deep joined up thinking, by doing a long term gas deal and the Grain LNG Terminal purchase so that they have the gas to supply and somewhere to keep it, until it is needed.
