What is a battery energy storage system (BESS)?

BESS stands for Battery Energy Storage Systems, which store energy generated from renewable sources like solar or wind. The stored energy can then be used when demand is high, ensuring a stable and reliable energy supply.

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 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.

How much does a Bess battery cost?

Factoring in these costs from the beginning ensures there are no unexpected expenses when the battery reaches the end of its useful life. To better understand BESS costs, it’s useful to look at the cost per kilowatt-hour (kWh) stored. As of recent data, the average cost of a BESS is approximately $400-$600 per kWh. Here’s a simple breakdown:

What factors affect the cost of a Bess system?

Several factors can influence the cost of a BESS, including: Larger systems cost more, but they often provide better value per kWh due to economies of scale. For instance, utility-scale projects benefit from bulk purchasing and reduced per-unit costs compared to residential installations. Costs can vary depending on where the system is installed.

How will localization and the cost of batteries affect Bess projects?

ompetition among battery makers.15 BNEF, ‘Localization and the Cost of Batteries’ (2024).Thus, lower battery supply chain prices, battery improvements including the uptake of larger cells at a record pace and intense competition in the sector will continue to drive down costs for BESS projects even further, whereas stationary
