GENsmart STOR Scheme

What is GENsmart?

What is the National Grid STOR scheme?

The National Grid STOR scheme allows companies to receive payments by removing or reducing their load from the National Grid during times of peak power usage when called upon (a ‘dispatch’).

This can be done either by reducing your energy power usage during these peak times (effectively removing your energy load from the grid), or more commonly, using your own generator to cover your needs during a ‘despatch’. The result is that it removes your need for power from the grid during that time period. The STOR programme will then pay you for the power that you have ‘removed’ from the grid during the despatches over a monthly period.

How much power do I have to remove from the grid to be part of the scheme? To become a STOR partner through our GENsmart scheme you must be able to:

What’s the cost to me?

There is absolutely no cost or ‘catch’ to participating in the GENsmart scheme (dependent on your installation type). All that is required is that you are available to respond to a dispatch when called upon at the times within your agreement.

How GENsmart payments work.

Payments within the GENsmart scheme are made up of 2 parts;

1) Availability payments

This is a payment made by the GENsmart programme based simply on your ‘overall availability’ to participate in the scheme when a despatch/event is called and the overall energy which you are capable of removing from the grid (in kW) during that period.

The overall availability hours are set by the National Grid and are defined by them at the start of each year.

In general, participation in the scheme assumes full availability (unless outlined in the participation agreement) and on average despatches will occur once a week over a full year.

2) ‘Event’ (despatch) payments

This is the payment made for actually removing your energy load from the grid when required, during a despatch, which will occur approximately once a week over the year (average of 50 dispatches per year).

Example payments:

The example payments below are an estimation of the expected income which you could receive assuming full availability over an operational year, based on an availability payment of £7.00 per MW and an event payment of £210 per MW taken from the grid.

Payments shown are annual totals for agreed energy removal from the grid.


Balancing supply and demand on the electrical grid for the National Grid is a constant challenge. Power plants break down, renewable power is variable and intermittent and consumer energy usage sometimes spikes. These constant fluctuations threaten the reliability of the grid and drive up energy prices.

To address imbalances between energy supply and demand, National Grid relies on STOR resources such as those offered by GENsmart which are despatched when supply and demand are out of balance. UPS Systems has partnered with the National Grid to offer our customers the opportunity to participate in the STOR scheme to help create a broad demand response network that serves as a ‘virtual power plant’, ready to provide additional power to the grid when needed most and support the grid.

Simply contact us to make an appointment and we can take care of all the details leaving you to concentrate on your business.


If the National grid anticipates a need for additional power it will first contact our operations centre who will then notify you that a despatch will occur in the next 15-20 mins (18 mins on average, 20 minutes maximum).

You will then change over to generator power or reduce your energy consumption at the previously determined level as per your agreed reduction plan.

In general, each despatch will last approximately one hour. Before, during and after each despatch you will continue to have access to full communications with the operations centre as our personnel are available 24 hours a day, 365 days a year.

To a degree yes if you are using a generator as your prime power source during a despatch.
