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.
