We are always reviewing the market and services available. There are loads out there that aren't worth the cost associated to providing the service, so we always make sure there is money to be made for our customers before we agree to any services.
Here are some of the markets we work (or will be working) in:
Frequency Response: Operated by National Grid this service makes you money by being available to either provide or taking energy off of the grid - to ensure a frequency level is maintained. More recently these contracts can often come under the threshold required to be worth while, so we only participate when the contracts provide the value we need. You can read more on Frequency Response here.
Demand Flexibility Service (DFS): Operated by ESO - a part of National Grid, this service makes you money through reducing your demand of energy required, at specific times of the day. ESO announce times, and we then prioritise your battery for consumption in those periods - to therefore reduce your pull from the grid. You can read more about this service here.
Dynamic Containment: (DC) Not currently provided, this is a relatively new service deployed by National Grid ESO, which is intended to support the grid system during frequency disturbances. This is one of the services replacing Frequency Response mentioned above.
Static Firm Frequency Response: (SFFR) is a service deployed by National Grid ESO, also intended to support the grid system during frequency disturbances. Although this one is only in one direction - providing energy when there is a shortfall. You can read more about this service here.
Local Constraint Market: The Local Constraint Market (LCM) provides flexibility to help manage local constraints in Scotland (B4 and B6 boundaries). As more and more renewable generation gets built in Scotland the boundaries that support transferring that energy becomes more constrained. You make money by supporting the storage of that energy at non peak times. You can read more about this here.
Constraint management zones: A service provided by 4 Network operators to better manage the distribution of their customers demand and generation. This is a geographic region served by an existing networks where network requirements related to network security of supply are met through the use of flexible services, such as Demand Side Response, Energy Storage and stand-by generation.
