How does Bess support Germany's energy transition?

By ensuring energy resilience, reliability, and sustainability, BESS aligns with Germany’s vision for a carbon-neutral future and sets a benchmark for the global energy transition. Enabling Germany's Energy Transition requires an economically sustainable model to attract necessary private capital.

Does Spain need a Bess energy system?

Currently, Spain has 6.3GW of hydroelectric and 1GW of thermal storage capacity installed. In fact, the non-BESS storage capacity in Spain is higher than in any other European country. As a result, the need for BESS to integrate renewable energy sources into the electricity system is less immediate than in the UK, for example.

Where is Bess available in Europe?

The UK, Italy, Germany and Spain are the four largest markets for BESS in Europe. Figure 1. New capacity forecasts for top 10 European grid-scale energy storage markets 2022-2031 (GWh). Source: Wood Mackenzie.

What is the market share of Bess batteries in 2023?

With a 72.3% market share, lithium-ion batteries dominate grid scale BESS applications and are set to remain the top choice for future needs. Germany led the European BESS market in 2023, with a 34% share, followed by Italy at 22% and the UK at 15%.

How many Bess projects are there in Spain?

In March 2025, UK companies Renewco and Atlantica announced the development of up to 2.2GW of BESS projects across Spain. Other projects in the pipeline primarily involve storage co-located with solar or wind generation. According to BloombergNEF, the total capacity currently in the BESS pipeline is around 3GW.

What is a Bess system & how does it work?

Installed on the site of a renewable energy plant, BESS can store surplus energy during periods of high generation and release it when demand peaks or during periods of low renewable energy production or even when available capacity in the grid exists.
