Battery Energy Storage Systems, also called BESS, is a technological solution that helps to balance the electricity grid in real time. Electricity flows on the grid may fluctuate due to various reasons, such as weather, power station outages, congestion on the grid, or geopolitical reasons.
Intelligent Battery Energy Storage Systems can complement the grid by providing a continuous power flow, making them a key pillar of your business energy strategy.
Made Simple – Battery Energy Storage System (BESS)BESS will be charging either straight from the power grid or from a renewable energy resource, such as solar or wind power.
The system then discharges the electricity back into the grid when it’s economically convenient e.g. during peak hours or following specific balancing orders from the Local Transmissions System Operators (TSOs).
From a high-level basic technical standing point, Battery Energy Storage Systems can be connected in front of the meter when directly connected to the transmission grid (for utility-scale installations) or behind the meter when connected to a local distribution network.
BESS are expected to provide fast response and efficient intraday flexibility, with storage duration ranging from a few seconds to 4-8 hours. For such a reason, they might be retained as an excellent fast responsive and efficient backup system for relatively short-term balancing needs, compared to Pumped Hydro Storage and thermal peaking plants that can cover power flexibility needs over a longer period.
ENGIE Global Energy Management & Sales is assessing several optimization tooling systems to properly optimize BESS and ensure a valuable full integration into the local Geographical environments and market designs, including the most recent ones relying on machine learning and AI.
Battery Energy Storage Systems allow you to engage in energy arbitrage. With BESS, you buy your energy during off-peak hours when grid prices are lowest, store it, and use it during peak hours. When coupled with on-site wind or solar power plants, BESS enable you to maximize the value of the electricity produced from such renewable sources, contributing to a certain extent to reducing the cost of energy both at the wholesale level and hence reflecting it on electricity bills.
Additionally, Battery Energy Storage Systems can play a central role in providing valuable and potentially highly remunerated energy services (such as electricity frequency regulation or electricity volume balancing in real-time) to the grid through the local TSOs, supporting them in facing the challenges arising from higher penetration of renewable energy sources such as solar and wind into the grid.
Battery Energy Storage Systems (BESS) can offer several environmental advantages and therefore significantly impact the energy transition. A few of them are:
With a presence in more than 50 countries, ENGIE Global Energy Management & Sales serves over 190,000 clients worldwide, granting us access to extensive data on energy consumption on both global and local levels.
Our trading division, ENGIE Global Markets, offers optimal energy rates, enabling you to store energy at the most favorable prices.
Battery Energy Storage Systems (BESS) have become an increasingly popular solution to the challenges posed by renewable energy integration and grid instability.
ENGIE group has been working at the forefront of developing BESS solutions. So far, one of our biggest Battery Energy Storage System projects is the construction of a 150 MW battery at the Hazelwood site in Victoria, Australia. This project will play a critical role in increasing renewable energy capacity in Victoria and the national energy grid.
ENGIE Global Energy Management & Sales is committed to continuing to develop BESS solutions and exploring new ways to maximize the potential of these technologies.
“Renewable energy has been the predominant solution for addressing the world’s energy needs since the early 2000s, with widespread adoption throughout the EU and beyond. We become more and more dependent on e-mobility and are excited to discover more about what battery storage can contribute to it.
We aim to continue developing solutions to decarbonize industries and ensure reliable, resilient, and flexible electricity networks worldwide.” Dario Acquarulo, Managing Director Italy for ENGIE Global Energy Management & Sales.
