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.

Which energy company is launching a Bess system in Ireland?

Last July, Neoen Renewables Ireland Ltd, a French renewable energy company, announced a 149.6MW BESS on an 8.5ac site near Portarlington, Laois. Just last week, the ESB opened a 75MW/150MWh BESS at the Poolbeg Energy Hub in Dublin. The system is Ireland’s largest so far and is part of its €300m BESS portfolio.

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:

Can energy storage be decarbonised in Ireland?

A critical point has been reached in the deployment of energy storage in Ireland. Power system development plans forecast that to achieve decarbonisation of the power system a large increase in the volume of ESS is required to assist in integrating the necessary volumes of variable renewable energy (VRE).

How much does Bess cost?

The cost of BESS has fallen significantly over the past decade, with more precipitous drops in recent years: This is nearly a 70% reduction in three years, owing to falling battery pack prices (now as low as $60-70/kWh in China), increased deployment, and improved efficiency.

Which energy companies are bringing a battery storage plant to Ireland?

Last October, Siemens Energy shared plans to bring a hybrid grid stabilisation and battery storage plant to Ireland. The large-scale battery storage system will have a capacity of around 160MWh. Last July, Neoen Renewables Ireland Ltd, a French renewable energy company, announced a 149.6MW BESS on an 8.5ac site near Portarlington, Laois.
