Battery Storage Technology for Buildings: The Main Reasons and Benefits
In an age where electricity is the lifeblood of our tech-driven and modern world, planning and providing for a reliable power supply is crucial for the functionality and safety of buildings. One innovative solution gaining momentum is the design and integration of battery storage and back-up systems. Envision Engineering is at the forefront of this trend and working with an increasing number of clients to explore applications for battery storage technology. Here's an overview of the main reasons and benefits:
What? Battery Backup Power.
Why? More Capacity for Uninterrupted Power Supply.
One of the primary advantages of incorporating battery back-up power is additional capacity for an uninterrupted power supply (UPS) using stored energy from renewable sources like solar and wind. In the event of grid failures, natural disasters, or other unforeseen circumstances, these systems act as a safeguard and provide a seamless transition to stored energy. "Batteries provide reserve capacity without interruption to selected loads and can supplement on-site generators with additional run-time during utility power outages," said Jeff Owen, President of Envision Engineering and a recognized thought-leader in sustainable energy solutions in Utah. This proves invaluable for critical operations within buildings such as hospitals, data centers, and emergency services.
"We're continually communicating with clients about the benefits of battery storage," said Owen. For example, Envision Engineering is currently conducting a battery storage study for the Utah National Guard to support their mission for emergency preparedness and disaster relief. The Guard's ultimate UPS goal? To power operations for two weeks without electricity. The study is evaluating the benefits and cost/payback scenarios of adding additional solar panels and storing that energy in battery systems to supplement the existing diesel-powered back-up generators and solar panels the Guard currently maintains.
What? Frequency Regulation and Voltage Stability.
Why? Grid Independence and Resilience.
Battery systems provide for frequency regulation and voltage stability—important conditions that lead to reliability as well as protecting important and costly equipment from damage. Battery back-up power also allows buildings to become less reliant on the traditional power grid. This enhances the overall resilience of the structure but also contributes to reducing the strain on public utilities during peak demand periods. In times of crisis or when the grid is under stress, buildings with independent power sources can continue to function.
What? Reduce Peak Demands and Time-of-Use Bill Management.
Why? Cost Savings and Energy Efficiency.
While the initial investment in battery back-up systems may seem significant, the long-term benefits can often outweigh the costs. Battery systems can be designed for "time-of-use" bill management—considering how electricity prices vary based on the time of day. With batteries, energy can be drawn from the grid to be stored when demand and prices are low, then used during peak times when prices are high. This not only reduces energy costs but also contributes to a more efficient use of resources. "Peak demand on the facility generally only occurs for a few hours a day. Batteries can inject a surge of additional power into the grid during peaks helping to offset facility and demand charges. In the same way as time-of-use bill management, energy is stored during low-demand times to be released (and reduce power drawn from the grid) when demand is high," explained Owen.
What? Integration with Renewable Energy Sources.
Why? Sustainability, Conservation, and Environmental Responsibility.
Battery back-up power systems contribute to environmental sustainability. By reducing reliance on fossil fuels, buildings with these systems are implementing more sustainable practices. The synergy between battery back-up power systems and renewable energy sources is a key driver for their adoption. Buildings can harness solar or wind power, storing excess energy in batteries for later use. "One of the great benefits of battery storage is increased self-consumption; excess solar or other renewable power generated during the day can be stockpiled and not lost," said Owen.
In Summary
The benefits of designing battery back-up power for buildings contribute to a more resilient, cost-effective, and environmentally conscious approach to power consumption. As technology and the importance of sustainable practices continue to advance, integrating battery back-up power systems will likely become more common.
