Gore Street Contracts NEC For 100 MW Of Storage

The title of this post is the same as that of this article on the Solar Power Portal.

This is the introductory paragraph.

Gore Street Energy Storage Fund has awarded NEC Energy Solutions both EPC and long-term O&M contracts for 100MW of storage in Northern Ireland.

What I find most comforting, is the matter-of-fact tone of the article.

Although, the author does seem to think that MW and MWh are the same, when in fact MW is used to define the rate of energy used or transferred and MWh the quantity.

If you use one MW for an hour, that is one MWh.

Gore Street appear to have needed two 50 MW energy storage systems for Drumkee and Mullavilly in Northern Ireland to back up a solar farm investment.

And they appear to have just ordered them off the shelf from NEC, in much the way, an individual might buy a Tesla Powerwall for their house.

According to this article on OVO Energy, the average European house uses 3,600 kWh per year.As there are 8760 hours in a year, the average consumption for a year is 0.4 kW per hour.

So if we assume that these two energy storage systems can deliver 50 MW for an hour, the following can be said.

  • The total capacity of each system is 50 MWh.
  • Each system can supply  125,000 houses for an hour or 25,000 houses for five hours.
  • As each housing unit has an average occupancy of 2.66 people, this means that a 50 MWh battery could supply a town of 66,500 people, for five hours.

Note that Lowestoft in Suffolk has a population of 71,000.

These batteries are not small.

Gresham House Plots £58million Raise To Pursue Energy Storage Pipelines

The title of this post is the same as this article on Solar Power Portal.

The article shows how increasingly the City of London is moving to increase the energy storage capacity we need as more wind and solar power comes on-line.

I wouldn’t invest my money in something like this directly, but I wouldn’t object if my pension provider placed money in energy storage.

UK Listed Energy Storage Fund Seeks 182MW Battery Project Pipeline

The title of this post is the same as that of this article on Energy Storage News.

This is the first paragraph.

UK investment management firm Gresham House has confirmed it is to launch a fresh fund raising drive as it sets its sights on a new, 182MW pipeline of battery storage projects.

It is my belief as a Control Engineer, that if we move to renewable energy, like geothermal, hydro, solar, tidal, wave and wind, that the generating capacity must be backed up with large massive of energy storage.

  • The energy storage captures excess electricity when nobody needs to use it and feeds it back when consumption exceeds supply.
  • I suspect that the National Grid have done extensive simulations of the UK’s energy needs and that they have a model of how much energy storage is needed to support particular mixes and capacities of renewable energy.
  • Most of the storage will be lithium-ion or perhaps some of the newer developments, that are creeping into the renewable dictionary.
  • The cost of storage, its working life and performance must be well-known, which means that the investors can get a return, that satisfies their needs to fund pensions and insurance policies.

So it would appear that Gresham House have done their sums and come up with a mathematical model, where all are winners.

  • UK industry and consumers get enough electricity for their needs.
  • Insurance companies and pension funds get a return to fulfil their contractual commitments.
  • UK pensioners get a reliable pension.
  • UK taxpayers don’t have to fund the much-needed energy storage.
  • Our electricity will increasingly be generated by renewables.
  • I do suspect that Gresham House will take an appropriate fee.

There may even be an opportunity for the public to invest directly in the future.

For all these winners, there will be losers.

  • Oil companies. In Writing On The Wall For Oil Say Funds, I wrote about the opinion of fund managers on oil companies.
  • Despots, dictators and religious maniacs, who control much of the world’s oil resources.

I shall cry not one tear for the second group!

I’ll be very interested to see the way that these energy storage funds develop!

Conclusion

These funds will develop in parallel with renewable energy and the energy storage it needs.

As the demand for energy storage will grow significantly, these funds will grow as well to provide the capacity needed to keep the lights on.

South Australia Launches AU$50 Million Fund For Grid-Scale Energy Storage

The title of this post is the same as that of this article on Energy Storage News.

This is the first paragraph.

In order to address intermittency in its grid, the South Australian Government has introduced a AU$50 million (US$36 million) Grid Scale Storage Fund (GSSF) to help accelerate the deployment of new large energy storage projects, including pumped hydro, hydrogen, gas storage, solar thermal, bioenergy and battery storage.

It is a must-read article, which shows the way progressive governments are thinking.

19MW Storage Capacity To Participate In Three UK Flexible Markets

The title of this post is the same as that of this article on Smart Energy.

in Batteries On The Boil As Fund Attracts Investors, I talked about energy storage funds, which are a way of investing in energy storage to add capabilities to electricity grids.

This article talks about how the Gore Street Energy Fund is investing in two energy storage facilities at the Port of Tilbury and Lower Road in Essex

I have also found this article on Solar Power Portal, which is entitled Gore Street Fund Makes New Battery Acquisitions With New 19MW Pair From Origami Energy.

The second article has a picture of a 4 MW/4.8 MWh Tesla battery at Cenin Renewables.

The link to Tesla gives a well-presented page of applications of these batteries.

One example given is Renewable Integration, where this is said.

Smooth and firm the output of a renewable power generation source such as wind or solar.

This will be a large application for these types of large batteries, as although we don’t have masses of sun, we do have a lot of wind.

Big financial institutions like Pension Funds and Insurance Companies need secure long term investment to place their money and these energy storage devices, would appear to offer a sensible return, that enables them to pay their investors, like anybody who has a pension. Traditionally,these financial institutions have invested in property and government bonds for example.

Lately, they have been investing in railway rolling stock, which have a life of up to forty years. These energy storage systems should offer a reasonable life, if well-maintained and updated.

As there will large numbers of energy  storage systems installed in the UK in the next decades, I think they could be a big area for investment.

At an individual level, we will also see houses built or refurbished with solar panels and batteries.

We are at the start of an exciting revolution!

Mathematics Of Energy Storage

I am particularly talking about the sort of energy storage that is attracting the attention of Energy Storage Funds, that I wrote about in Batteries On The Boil As Fund Attracts Investors.

The Times article of the same name has this paragraph.

A typical 50-megawatt energy storage site of the kind the company intends to acquire hosts 19 containers each housing thousands of lithium-ion cells. A fully-charged container has the energy to boil 32,000 kettles.

This page on ConfusedEnergy.co.uk, says this.

We are often told to only use as much water as we need in a kettle and not to fill it to the top, but what are the potential annual saving in doing this. Well it takes roughly 4.5 minutes to boil a full (2 litre) kettle with a power rating of 3kW (kilowatts).

This means that to boil a kettle needs 0.225 kWh.

  • Boiling 32,000 kettles needs 7200 kWh or 7.2 MWh
  • Which means that the total capacity of the nineteen container energy storage facility is 136.8 MWh.

So the energy storage could provide the rated 50 MW for nearly three hours.

Lithium-Ion Batteries, Supercapacitors Or Both?

The article in The Times doesn’t mention supercapacitors.

If you watch the video in A Must-Watch Video About Skeleton Technologies And Ultracapacitors, Skeleton Technologies state the following about their ultracapacitors.

  • They are more affordable.
  • They generate less heat.
  • They have a higher energy density.
  • They can handle more charge/discharge cycles.
  • They have a faster response time, so would respond better to sudden demands.

I suspect there may be several operational and financial advantages, in replacing some of the lithium-ion batteries with supercapacitors.

Batteries On The Boil As Fund Attracts Investors

The title of this post is the same as that of an article in the Business section of today’s Times.

This is the first two paragraph.

Investors have sunk £100million into a new listed company that aims to use shipping containers packed with lithium-ion batteries to buy, store and sell electricity.

Gresham House Energy Storage Fund claims that it will make a return of 15 per ceent a year by providing electricity when surges in demand coincide with periods when the wind is not blowing  or the sun is not shining.

Gresham House Energy Storage Fund is the second listed energy storage fund in London, after Gore Street Energy Storage Fund , launched in May.

I think we’ll see more of these funds and use of the technology.

Suppose you were a farmer with a windy hill top farm, that had a heavy electricity bill.

Realistically, sized, priced and financed a  wind-turbine and a container full of batteries, might be just what your finances wanted.

All you’d need now would be an electric Range-Rover and a fleet of electric tractors!
