Battery Energy Storage System (BESS)
A power pack package of clean energy, from microgrids to utility-scale solar installations, our solutions help in accelerating the transition from other power sources to renewable energy sources. Learn more about how we are making clean energy a reality globally.
Energy storage benefits both utilities and energy consumers in a variety of ways.
- Address the intermittency of renewable power.
- Rapid response to the demand of large fluctuations, making grids more responsive.
- Reduces the need to build a backup fossil fuel-based power plant.
- Meets electricity demand during peak times, such as on hot summer days when air conditioners are blasting or at nightfall when households turn on their lights and electronics.
- Electricity becomes more expensive during peak times as power plants ramp up production to accommodate the increase in energy usage.
- Commercial and industrial facilities pay ‘demand charges’ by utilities, typically 15-25% percent of their energy bill. There is an estimate that over 20 million commercial customers across the country may be able to achieve electricity cost savings by deploying battery storage to manage peak demand.
Utilities
- Demand Management
- Spinning reserve: Secondary / Tertiary ancillary services
- Resilience to Grid and RE assets
- Improve transmission network by removing congestion
Renewable
- Power firming to make it reliable and predictable
- Round-the-clock Green Power via ESS Solution
- Ease scheduling of power
- Peak time supply/merchant market energy trading
Commercial & Industrial
- Reduce expensive and carbon intensive DGs with BESS for critical back-up
- Power quality improvement
- Backup for critical loads
- Green Microgrids
- BESS with captive Solar / Wind plant for asset optimization
Application & Benefits
- Project Lifetime: Lifetime of the project compared to usable lifetime of battery technology.
- Duty Cycles: The number of annual full charges/discharges can impact degradation.
- Depth of Discharge: The depth the battery is discharged, affects usable capacity and degradation.
- Average Rest State of Charge: Average charge of the system while not in use, which affects availability and degradation.
- Safety: Fire, toxicity, environmental or other risk factors.
- Technology Maturity: With battery innovation occurring, is the technology mature enough for deployment at scale?
What to Consider For a New Energy Storage System
-
Identifying the business problem :
Type of application to consider and how BESS can solve the issues at hand -
Technical integration :
Selecting the type of Topology as required by the project -
Project life :
Identifying the project's life as per use case -
System reliability and safety selection :
Identifying the certification required for safety of the complete system -
Engineering aspect :
Identifying key system configuration, batteries, PCS, EMS and how it will combine and communicate with each other (native integration recommended)
The value of fast-acting energy storage is often difficult to comprehend, but it can become the backbone of commercial and industrial establishments when grids go down.
