Time-Shifting (Energy Arbitrage)

The battery stores electricity when power is cheap or abundant (e.g., solar generation during midday or off-peak hours) and discharges when electricity prices are high (peak demand periods).

Example:

A utility charges the battery at ₹2–4/kWh during solar-heavy daytime hours and discharges at ₹8–12/kWh during evening peak demand.

Value Created:

  • Lower electricity procurement cost
  • Peak price arbitrage
  • Better renewable energy utilization

Peak Shaving (Demand Charge Reduction)

The battery reduces short-duration power peaks, lowering demand charges or peak procurement costs. The battery discharges only during the highest consumption periods to flatten the demand profile.

Example:

A factory spikes to 500 MW for 30 minutes every evening. A battery discharges 125 MW during that period, reducing billed peak demand to 375 MW.

Value Created:

  • Lower demand charges (especially for C&I customers)
  • Reduced maximum contracted demand penalties
  • Better load profile management

DG (Diesel Genset) Avoidance

Batteries can reduce or completely eliminate the need to run diesel generators (DG sets) during power outages, leading to fuel cost savings of multiple order.

Example:

A facility running on DG cost of INR 30-35 per kWh can be reduced to less than 1/3rd by utilising BESS with a run time of upto 4 hours.

Value Created:

  • Fuel cost savings (diesel is expensive and volatile)
  • Lower O&M costs vs DG maintenance
  • Reduced carbon emissions and air pollution
  • Instant backup power (milliseconds vs DG startup delay)

Green Charging Solutioning

A BESS can store electricity from solar, wind, or low-carbon grid power and then use it to charge electric vehicles when needed, reducing dependence on fossil-fuel-heavy and expensive grid electricity, minimizing peak demand stress and carbon footprint.

Example (EV Charging Hub):

An EV fast-charging station requiring 1 MW power may only have a 400 kW grid connection. A battery charges gradually from the grid/solar and discharges during peak EV charging sessions, enabling ultra-fast charging without major grid upgrades.

Value Created:

  • Higher renewable energy utilization
  • Reduced grid demand charges and lower electricity costs
  • Faster EV charging without upgrading grid connection
  • Lower carbon footprint for fleets and charging operators
  • Improved charging reliability during grid instability
