Energy Storage Project Duty

Should a solar project include battery storage?

While from a solar developer’s perspective, exploring the addition of battery storage usually makes sense, some battery developers may be more focused on grid capacity than incorporating solar or other renewable energy into the project. These developers may decide not to locate their project next to a renewable energy asset.

What is a battery energy storage system?

As renewable capacity is added to the grid, the need to store and flexibly manage electricity grows with it. This is where the crucial role of battery energy storage systems (BESS) come into play, storing and releasing energy for when it’s needed most. We look at what’s happening with the growth of BESS in the UK.

Should energy storage assets be co-located?

Energy generated in periods of high production can be stored and then released during times of high demand or low generation, which alleviates intermittency risk. Storage assets can generate revenue through arbitrage during periods of lower natural generation. However, there are challenges associated with co-locating assets.

What is long duration electricity storage (LDEs)?

Long Duration Electricity Storage (LDES) technologies contribute to decarbonising and making our energy system more resilient by storing electricity and releasing it when needed. LDES can also help reduce costs for consumers through reducing their bills and by avoiding the need for expensive electricity grid upgrades.

How big is Europe's largest battery storage project?

A decade ago the average project size was just 2MW, and by 2021 it had grown to 54MW. When it energised in 2021, the 100MW/136MWh Minety development in Wiltshire was Europe’s largest operational battery storage project at the time.

What is the 'cap and floor' regime for long duration electricity storage (LDEs)?

Ofgem is the regulator for Long Duration Electricity Storage and oversees implementation of a 'cap and floor' regime for LDES projects, proposed by the Department for Energy Security and Net Zero (DESNZ). The aim of this regime is to stimulate investment in Long Duration Electricity Storage projects.
