Battery Energy Storage Systems (BESS)
Commercial & Regulatory
- Store energy generated by renewables during hours of maximum delivery and use it during peaks, thus flattening the variance between day and evening on conventional generation plant output. This in turn is expected to increase the efficiency of the conventional plant in operation and thus reduce its emissions. Excess RES generated will be stored and then used to displace the starting up/ramping up of CO2 emitting plants.
- Reduce the effect of the variability and intermittency caused by renewables, in periods of variable cloud cover, and thus permit the operation of conventional plant in a more stable manner, with inherent gains in plant reliability, plant emissions and CO2 emission savings.
- Provide a source of secure supply in cases of plant outages thereby enhancing the grid’s resilience and stability,
- Address grid bottlenecks to accelerate the penetration of RES and offer solutions to alleviate congestion in the distribution network,
- Provide black start facility capable of restarting the power station and grid in the event of a total shutdown and supply power to part of the network.
- Enable the ingress of further RES, including large-scale renewable energy offshore projects, thereby reducing the use of fossil fuels for electricity generation
- Provide fast frequency and voltage stabilisation to the Maltese grid in case Malta is isolated from the Italian grid because of maintenance or faults.

BESS Project Engineering, Procurement and Construction
Start of Operation BESS 1 and BESS 2
The BESS project will be split into two main projects
The first Project (BESS 1) will be funded from the Recovery and Resilience Fund (RRF) and is planned to be located at close proximity to the Marsa North Distribution Centre.
The second Project (BESS 2) will have a larger capacity than the first and will be funded from the ERDF programme. This storage system will be located within the precincts of the Delimara Power Station.
