A battery energy storage system (BESS) is an advanced technology solution that can store energy for later use in a variety of ways. Given that energy supply can fluctuate due to weather, blackouts or geopolitical reasons, battery systems are essential for achieving a continuous supply of electricity to utilities, businesses and homes. No longer an afterthought or an add-on, battery energy storage systems are an essential pillar of any energy strategy, especially any energy strategy that harnesses renewable solar energy. The sun is a fantastic energy engine, but it has an important limitation: without sunlight, you can’t generate electricity. By combining battery energy storage with photovoltaic solutions, batteries can mitigate the intermittency of renewable energy, storing solar energy generated during the day for use at night, ensuring a stable supply of electricity is always available.
Description
A battery energy storage system (BESS) works by receiving electrical energy from the grid, power stations or renewable or other energy sources such as solar panels, then storing it as current and then releasing it when needed. When combined with software, BESS batteries become a platform that combines the energy storage capacity of batteries with the intelligence required to achieve advanced energy consumption management by leveraging artificial intelligence, machine learning and data-driven solutions. This makes batteries a tool to offset climate change because they enable users to use energy more flexibly, allowing users to adapt to troughs and peaks in demand and supply.
Overall, battery energy storage systems facilitate the deployment of renewable energy, thereby helping to reduce carbon emissions and even lower costs for businesses and households.
Battery storage can be used in many ways that go beyond the simple emergency backup in the event of an energy shortage or blackout. Applications differ depending on whether the storage is being used for a business or a home.
For commercial and industrial users, there are several applications:
- Peak shaving, which is the ability to manage energy demand to avoid sudden spikes in energy consumption in the short term
- Load shifting, which allows businesses to shift energy consumption from one time period to another by leveraging batteries when energy costs are high
- Flexibility, where customers can reduce grid demand at their site at critical times without changing their electricity consumption. Energy storage, therefore, makes it easier to participate in demand response programs and save energy costs
- Integrated solutions to save energy and grow your business
- Microgrids rely on batteries as a key component, as these grids require energy storage to disconnect from the main grid when needed
- Integration with renewable energy sources, as batteries can guarantee a smooth and continuous flow of electricity when renewable energy is not available.
Residential users benefit from applying energy storage systems in the following ways:
- Self-use, as residential users can produce solar energy during the day and then run their home’s appliances at night
- Emergency backup power during power outages
- Going off the grid, or completely disconnecting from the power or energy utility
Advantages of battery energy storage system
- Environmental benefits: Installing a renewable energy battery storage system at a home or business reduces pollution, thereby contributing to the energy transition and combating the effects of global warming.
- Reduced energy costs: Storing low-cost energy and using it during peak hours when electricity rates are higher saves money by allowing users to shift consumption and avoid higher bills. When combined with free solar energy, the savings are even greater.
- Reduced reliance on the grid: Battery storage systems guarantee a continuous supply of energy, even when the grid is unstable due to peak demand or extreme weather.
- “Always on” power supply: The sun is not always “on”. Battery storage systems work 24/7 so any fluctuations in solar supply can be compensated by storing excess power in the system.
- Resilience: Battery storage systems provide emergency backup power during power outages, ensuring business continuity.
