BESS Projects Represent ‘Encouraging Progress’ in New York Efforts To Replace Dirty And Polluting Peakers
The title of this post, is the same as that of this article on Energy Storage News.
These are the first three paragraphs.
Battery storage is playing an active role in helping New York City retire its fleet of peaker power plants, with around 700MW of its most polluting power generation assets already fully retired.
According to a new report, 4,019MW – about two-thirds of a 6,093MW fleet – has either retired or put in place plans to replace turbines with cleaner technologies since New York adopted its climate goals and environment protection policies in 2019.
In addition to 700MW already retired, around the same amount again is actively being moved towards end of life.
Note.
- Just over 6,000 MW seems a lot of extra peaker power, even for a city as large as New York.
- But at least over 4 GW has been retired or the plans to replace it with cleaner technologies are in place.
- The New Yorkers certainly seem to be getting on with the conversion, with about a GW/per year either retired or planned to do so.
The article says this about batteries.
Battery storage is one of a number of different technologies that can be used to replace peaking capacity. While lithium-ion batteries with 4-hour duration might be the most directly analogous in terms of technical capability to peakers, effectively retiring the power plants could be facilitated with a combination of other resources including rooftop solar, offshore wind and energy efficiency measures.
I find the 4-hour duration interesting, but I suspect the Yanks know what they’re doing.
So if you were going to replace the 240 MW Glanford Brigg power station, which Centrica describe as a peaker station, with energy storage, you’d use a 240 MW/960 MWh battery, if you were working to New York rules.
Batteries in the UK, that I’ve talked about lately include.
Amp Hunterston – 400 MW/800 MWh – 2 hours
Amp Kincardine – 400 MW/800 MWh – 2 hours
- Carlton Energy Park – 1040 MW/2080 MWh – 2 hours – Close to an 884 MW gas-fired power station.
- Coalburn – 500 MW/1000 MWh – 2 hours- Close to a 946 MW collection of wind farms.
- Gateway Energy Centre – 450 MW/900 MWh – 2 hours – Close to an 732 MW gas-fired power station.
- Normanton Energy Reserve – 500 MW/1000 MWh – 2 hours
- Richborough Energy Park – 100 MW/100 MWh – 1 hour
- Spalding Energy Centre – 550 MW/1100 MWh – 2 hours – Close to an 860 MW gas-fired power station.
Note.
- The first field is Output/Storage Capacity.
- The second field is the duration.
- I have assumed Spalding Energy Centre is another two hour duration system, like Gateway Energy Centre, which is also being developed by Intergen.
- Two hours seems to be the most common duration for a UK battery.
Adding the batteries up gives a virtual 3940MW/7780MWh battery.
It amazing how they add up to quite large values. But then every little helps!
And these are only the ones I’ve talked about.
InterGen’s Two Huge Batteries
InterGen are developing two huge lithium-ion batteries, which seem to be rather under the radar of the mainstream media.
InterGen are an energy company, of which few people have heard.
On the About InterGen page, this is the sub-heading of a section describing their business.
InterGen is a uniquely independent energy company. We support the journey to a stable, dependable, net zero energy system through delivering the flexible electricity solutions that underpin it.
These four paragraphs introduce the business.
Founded in 1995, we have decades of experience in the GB market.
Our power stations provide secure, flexible energy to consumers, and help the grid to take on more and more renewables.
Our expert trading team in Edinburgh sells electricity and services to help utilities, system operators and the wider energy market deliver secure power to homes and businesses across the country, whilst our pipeline of new developments includes some of the world’s largest battery storage assets, an essential component in the future energy system.
The world is changing, and we’re proud to be playing an active role in the unfolding energy story for generations to come.
Batteries are very much for generations to come.
These four paragraphs on this page says this about their batteries.
Developing a large-scale energy storage capability will help to resolve the challenge of the intermittency of renewable generation. At InterGen, we’re managing the delivery of one of Europe’s largest battery storage portfolios, with over 2GW of grid scale projects, having dedicated grid connections and proceeding through the permitting process.
The share of wind and solar power is increasing in the UK’s energy mix, but these sources only generate power when the wind blows or the sun shines. The use of batteries to store the excess power generated can help provide low carbon power to balance supply and demand with renewable power during periods of low output.
InterGen’s UK battery projects are world-leading in this kind of technology deployment. The facilities will use proven lithium-ion technology which has zero emissions, has superior flexibility, and will complement the increasing amounts of renewable energy generation in the UK.
In Essex, our project at London Gateway Port to create up to 900MWh of energy received planning permission in January 2023, and when complete will be large enough to provide power for up to 450,000 homes. At Spalding, we have consent to develop up to 1.1GWh of storage capability, adjacent to our existing operational CCGT and OCGT plants. Both of these developments are world-class in terms of size. It’s all part of our goal to support the transition to low carbon generation through the provision of flexible capacity.
Gateway Energy Centre
This page describes the Gateway Energy Centre, where this is said.
InterGen is in late stage development of a world leading battery storage project in the London Gateway Logistics Park, next to the DP World London Gateway Port on the north bank of the River Thames in Essex. InterGen built and continues to operate the existing 800 MW Coryton gas-fired combined cycle power station which is located approximately one kilometre from the proposed Gateway Energy Centre site.
The Gateway project will consist of a Battery Energy Storage System (BESS) with a rated electrical output of up to 900MWh (up to 450MW).
InterGen received Town and Country Planning Permission in January 2023, making the Gateway project the largest battery in the UK once operational. The £300m project will provide power for over 450,000 homes once fully complete.
Note.
- I assume they mean this battery is a 450 MW/900 MWh battery, that will provide 450 MW for two hours.
- It is close to the 732 MW Coryton gas-fired combined cycle power station.
I would assume that one of its tasks will be to make sure the London Gateway complex gets rnough reliable power.
Spalding Energy Park
This page describes the Spalding Energy Park, where this is said.
The Spalding Energy Park, adjacent to InterGen’s existing combined and open cycle gas plants at Spalding, has received Town and Country Planning Permission in June 2023 for one of Europe’s largest battery storage projects. The battery development could deliver up to 1,100MWh of electricity once operational, providing power for up to 500,000 homes.
Spalding Energy Park received planning consent in January 2018 from the Department of Business, Energy and Industrial Strategy. The project is carbon capture ready.
As at Gateway Energy Centre, the battery is located close to a large 860 MW gas-fired power station.
Co-location of a gas-fired power station and a battery must make the grid connection simpler.
Conclusion
A total of 2 GWh of storage is a good start and I’ll suspect we’ll hear more about these two batteries in the next couple of years.
£100m Boost For Biggest UK Hydro Scheme In Decades
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
A giant hydro scheme which would double the UK’s ability to store energy for long periods is taking a leap forward with a £100m investment by SSE.
These are the first three paragraphs.
The proposed 92m-high dam and two reservoirs at Coire Glas in the Highlands would be Britain’s biggest hydroelectric project for 40 years.
Scottish ministers approved the 1.5 GW pumped storage facility in 2020.
But power giant SSE wants assurances from the UK government before finally signing it off.
There are two major problems with this scheme.
Why The Forty Year Wait?
I am an Electrical and Control Engineer and it is a scandal that we are waiting forty years for another pumped storage scheme like the successful Electric Mountain or Cruachan power stations to arrive.
Petrol or diesel vehicles have batteries for these three main purposes.
- To start the engine.
- To stabilise the output of the generator or alternator.
- To provide emergency power.
As to the latter, I can’t be the only person, who has dragged a car out of a ford on the starter motor. But think of the times, you’ve used the hazard warning lights, after an accident or an engine failure.
The nightmare of any operator of a complicated electricity network like the UK’s is a black start, which is defined by Wikipedia like this.
A black start is the process of restoring an electric power station or a part of an electric grid to operation without relying on the external electric power transmission network to recover from a total or partial shutdown.
Hydro electric power stations and especially those that are part of pumped storage schemes are ideal for providing the initial power, as they are often easy to start and have water available. Cruachan power station has a black start capability, but at 440 MW is it big enough?
Over the last few years, many lithium-ion batteries have been added to the UK power network, which are used to stabilise the grid, when the sun isn’t shining and the wind isn’t blowing.
There are four pumped storage hydro-electric schemes in the UK.
- Cruachan – 440 MW/7 GWh – 1965
- Dinorwig (Electric Mountain) – 1800 MW/9.1 GWh -1984
- Ffestiniog – 360MW/1.44 GWh – 1963
- Foyers – 300 MW/6.3 GWh – 1974
Note.
- I always give the power output and the storage capacity for a battery, if it is known.
- According to Wikipedia, Scotland has a potential for around 500 GWh of pumped storage.
- The largest lithium-ion battery that I know, that is being planned in the UK, is Intergen’s 320 MW/640 MWh battery at Thames Gateway, that I wrote about in Giant Batteries Will Provide Surge Of Electricity Storage. It’s smaller than any of the four current pumped storage schemes.
- The Wikipedia entry for Coire Glas says that it is a 1.5 GW/30 GWh pumped storage hydro-electric power station.
I very much feel that even one 1.5 GW/30 GWh pumped storage hydro-electric power station must make a big difference mathematically.
Why have we had to wait so long? It’s not as though a pumped storage hydro-electric power station of this size has suffered a serious disaster.
Drax Needs Assurances Too?
The BBC article says this.
Scotland’s only other pumped storage scheme, operated by Drax Group, is housed within a giant artificial cavern inside Ben Cruachan on the shores of Loch Awe in Argyll.
The North Yorkshire-based company plans to more than double the generating capacity of its facility, nicknamed Hollow Mountain, to more than 1GW, with the construction of a new underground power station.
But both Drax and SSE have been reluctant to press ahead without assurances from Whitehall.
It looks like the right assurances would open up at least two pumped storage hydro-electric power station projects.
But it could be better than that, as there are other projects under development.
- Balliemeanoch – 1.5GW/45 GWh
- Corrievarkie – 600 MW/14.5 GWh
- Loch Earba – 900 MW/33 GWh
- Loch Kemp – 300 MW/9 GWh
- Red John – 450 MW/2.8 GWh
This totals to 3750 MW/104.3 GWh or 5850 MW/134.3 GWh with the addition of Coire Glas and the extension to Cruachan.
Getting the assurances right could result in large amounts of construction in Scotland!
What Assurances Do Power Giants SSE And Drax Want Before Signing Off?
This news item on SSE Renewables, which is dated 18th March 2022, is entitled Ministerial Roundtable Seeks To Unlock Investment In UK Energy Storage.
These three paragraphs gives details of the meeting.
Business leaders have met with UK Energy Minister the Rt Hon Greg Hands MP to discuss how the government could unlock significant investment in vital energy storage technologies needed to decarbonise the power sector and help ensure greater energy independence.
The meeting was organised by the Long-Duration Electricity Storage Alliance, a new association of companies, progressing plans across a range of technologies to be first of their kind to be developed in the UK for decades.
Representatives from Drax, SSE Renewables, Highview Power and Invinity Energy Systems met with The Rt Hon Greg Hands MP, Minister of State for Business, Energy and Clean Growth [yesterday].
But they still don’t seem to have come up with a funding mechanism.
- In this case, it seems that multiple politicians may not be to blame, as Greg Hands was the Minister of State for Business, Energy and Clean Growth until the 6th of September 2022, when he handed over to Graham Stuart, who is still the incumbent.
- Could it be that civil servants for this problem need to be augmented by a Control Engineer with mathematical modelling skills from a practical university?
It is the sort of problem, I would love to get my teeth into, but unfortunately my three mentors in accountancy and banking; Bob, Brian and David, who could have helped me, have all passed on to another place to help someone else with their problems.
I’ve just had a virtual meeting with all three and they told me to look at it like a warehousing system.
Consider.
- It would be very easy to measure the amount of water stored in the upper reservoir of a pumped storage hydro-electric power station.
- It would also be easy to measure the electricity flows to and from the pumped storage hydro-electric power station.
- A monetary value could be placed on the water in the upper reservoir and the flows, depending on the current price for electricity.
So it should be possible to know that a pumped storage hydro-electric power station, was perhaps storing energy as follows.
- 10 GWh for SSE
- 8 GWh for RWE
- 6 GWh for Scottish Power
- 6 GWh is not being used
And just as in a warehouse, they would pay a fee of so much for storing each GWh for an hour.
- The system would work with any type of storage.
- Would competition between the various storage sites bring down prices for storing electricity?
- Pumped storage operators would get a bonus when it rained heavily.
- Just as they do now, electricity generators would store it when prices are low and retrieve it when prices are high.
A lot of the rules used to decide where electricity goes would still work.
Giant Batteries Will Provide Surge Of Electricity Storage
The title of this post, is the same as that of this article on The Times.
These are the first two paragraphs.
Britain’s capacity to store electricity in giant batteries is set to double after dozens of new projects won contracts through a government scheme to keep the lights on.
Developers of battery storage projects with a total output capacity of at least 3.3 gigawatts won contracts to operate from winter 2025-26 through the government’s “capacity market” auction, according to Cornwall Insight, the consultancy.
Note that Hinckley Point C is only 3.26 GW.
The biggest battery in these contracts is a giant that Intergen will be building at the London Gateway.
When the battery got planning permission in November 2020, Intergen published this press release, which is entitled InterGen Gains Consent To Build One Of The World’s Largest Battery Projects In Essex.
These are three bullet points at the head of the press release.
- Edinburgh-headquartered energy company InterGen has been granted planning consent to build the UK’s largest battery storage project at DP World London Gateway on the Thames Estuary.
- £200m project is set to provide at least 320MW/640MWh of capacity, with the potential to expand to 1.3GWh – more than ten times the size of the largest battery currently in operation in the UK and set to be one of the world’s largest.
- The battery will provide fast-reacting power and system balancing with an initial two-hour duration, and is a significant piece of infrastructure on the UK’s journey to net zero.
As Cilla might have said. “What a lorra lorra lot of lithium!”
But it’s not just lithium-ion batteries that are getting large.
In The Power Of Solar With A Large Battery, I talked about a Highview Power CRYOBattery with a capacity of 50MW/500MWh, that is being built in the Atacama desert in Chile.
The Essex battery is a giant battery and it’s bigger than the one in Chile, but I’m fairly sure Highview Power could build a battery bigger than the one InterGen are building. You just add more liquid air tanks and turbomachinery.
