As society becomes more conscious of its impact on the environment, sustainable energy solutions are being thrust
into the proverbial spotlight. To bridge this energy gap, Battery Energy Storage Systems (BESS) are playing a
major role in creating a cleaner, more reliable, and efficient power grid. This article dives into the advantages
of BESS solutions, explores their various applications, and discusses the benefits of these systems. Join us as we
explore how BESS is transforming the energy landscape and driving us toward a more sustainable future.
What Is BESS?
BESS solutions are designed to store electrical energy for later use. These advanced systems leverage various
types of batteries (such as lithium-ion, lead-acid, and flow batteries) to capture energy either from renewable
sources like solar and wind or during off-peak hours when electricity is cheaper and more abundantly available.
The stored energy power can then be released back into the grid or used directly by consumers during peak demand
times when energy is more expensive and less readily available. This helps manage energy costs and plays a vital
role in stabilizing the grid, especially with the fluctuating nature of sustainable energy sources.
Application Areas of BESS
BESS solutions are revolutionizing the way we store and utilize energy; let's explore the diverse application
areas where they're making a significant impact.
1. Capacity Markets
BESS contributes to capacity markets by providing a reliable backup electricity supply and enhancing grid
stability during peak demand periods or system stress. Capacity agreements in this market can extend up to 15
years, offering a stable revenue source for operators by ensuring that additional generation or demand reduction
capacity is available when needed.
2. Offtake Agreements
Through Offtake Agreements or Power Purchase Agreements (PPA), BESS sells stored electricity directly to consumers
or businesses at a negotiated price. These agreements can provide financial predictability and security for up to
15 years, facilitating the integration of stored renewable energy into the consumption patterns of end-users.
3. Dynamic Frequency Response
BESS is instrumental in maintaining grid frequency within the required operating parameters by providing dynamic
frequency response services. These involve the rapid reduction or increase of electricity discharged from the
storage system in response to fluctuations in grid demand, thereby ensuring operational reliability and avoiding
power outages.
4. Energy Arbitrage
By engaging in energy arbitrage, BESS operators can buy electricity when prices are low and store it for later use
or sell it during peak demand periods when prices are higher. This practice supports grid efficiency and promotes
sustainability by maximizing the use of green energy sources and reducing dependence on fossil fuels.
5. DS3 Programme
In Ireland, the DS3 (Delivering a Secure, Sustainable Electricity System) programme provides incentives for the
deployment of BESS to support the integration of sustainable energy, improving the grid's flexibility and
responsiveness. BESS under this programme provides essential ancillary services like frequency response and
reserve services, critical for maintaining grid stability amidst the fluctuating nature of renewable energy
sources.
Benefits of BESS
Environmental-Friendly
One of the biggest advantages of BESS lies in its positive environmental impact. Unlike traditional energy sources
that often involve burning harmful fossil fuels, BESS uses clean, renewable energy. By storing energy when
renewable resources such as wind and solar power produce excess energy, BESS reduces the reliance on less
environmentally friendly power sources, helping minimize greenhouse gas emissions and creating a more sustainable
energy future.
Reduce Energy Costs
Another benefit is cost efficiency. BESS allows energy arbitrage by storing electricity when prices are low and
discharging it when prices are high during peak times. This shift of energy use from high to low-cost periods
helps reduce overall energy costs.
Reduce Grid Dependency
By sourcing and storing power during non-peak times, BESS alleviates the stresses and strains on the grid during
peak demand periods. This self-sufficiency helps reduce dependency on the grid, making energy consumers less
susceptible to power outages and fluctuations in energy prices.
Minimize Electricity Bills
Similar to reducing energy costs, BESS can significantly minimize electricity bills. Consumers can store excess
generation for later use, negating the purchase of power from the grid during high-rate periods. Through
well-managed energy storage benefits, users can control their energy consumption and optimize their electricity
use, lowering their electricity bills.
Frequency Control
Last but not least, BESS provides a vital service in frequency control and power grid stabilization. They can
swiftly respond to network demand fluctuations by reducing or increasing their energy consumption, thereby
maintaining grid stability. Traditional power plants are slower to respond to grid needs than BESS, making them a
more attractive option for grid operators. Through the dynamic frequency response contracts, operators can
increase their income while maintaining grid stability.
