What is a standalone Bess solution?

Standalone BESS solutions can be dynamically sized to suit any long-duration storage requirement, typically sized from 100kW/ 400kWh to 40MW/ 160MWh. Standalone solutions are usually made up of multiple containerised units and can stand in any convenient location within, or even outside of, a customer’s existing plant.

What is the largest Bess planning consent in Scotland?

With a capacity of 700 megawatts (MW), this is the largest planning consent for a standalone BESS in Scotland to date and the biggest ever secured by Apatura. It is also the fourth consent in less than 12 months, and Apatura expects more to follow soon.

What is a Bess system?

A BESS is an advanced technology system designed to store electrical energy during periods of high generation and low demand which can then be exported back into the grid network during periods of high demand.

What is the difference between a Bess and a hybrid Bess?

In comparison to standalone BESSs, hybrid BESSs require a lower BESS capacity for the same FCR power. Therefore, each of the base scenarios 2 and 3 are further divided into three different E/P ratio variants named sub-scenarios A, B and C (cf. Table 1 ).

Why should you choose a standalone Bess?

The reason is that standalone BESSs not only have higher environmental impacts due to the higher battery capacity required but also provide more MWh FCR during the lifetime because of the different operational strategy applied.

How much energy does a Bess have to reserve for FCR?

Therefore, BESSs providing FCR have to reserve 0.25 MWh of their energy capacity for both positive as well as negative MW FCR at all times to fulfil this requirement (i.e. FCR energy capacity requirement).
