Solar + Battery Storage (BESS)


Round-the-clock green power. Eliminate diesel dependencies.

Overview

SparkGrid’s Battery Energy Storage Systems (BESS) integrated with Solar PV provide reliable, 24/7 clean energy, shielding your business from grid outages and expensive diesel generator costs.

Traditional solar power is limited to daytime generation. But what happens during night shifts, peak pricing hours, or sudden power cuts? Our advanced Solar + Storage solutions capture excess solar energy generated during the day and store it in high-efficiency lithium-ion batteries. This stored energy can be deployed instantly during outages (completely replacing noisy, polluting DG sets) or discharged during evening peak-tariff hours to maximize your financial savings. Welcome to true energy independence.

Diesel Gen Replacement

Completely eliminate or drastically reduce your reliance on expensive diesel generators, cutting fuel and maintenance costs.

Peak Load Shaving

Discharge stored battery power during expensive Time-of-Day (ToD) peak tariff hours to significantly reduce your DISCOM bill.

Uninterrupted Operations

BESS provides instantaneous backup power with zero switchover time, protecting sensitive equipment from grid fluctuations and sudden blackouts.


Maximize Solar ROI

Store excess weekend or afternoon solar generation instead of feeding it back to the grid at low net-metering rates.

Grid Stabilization

Smooth out the intermittent nature of solar power, ensuring high power quality (voltage and frequency regulation) for your facility.

Silent & Emission-Free

Unlike diesel generators, battery storage systems operate silently and emit zero greenhouse gases locally.

How Solar + BESS Works

Our intelligent Energy Management System (EMS) acts as the brain of your facility, seamlessly routing power between the solar panels, the grid, the batteries, and your load to ensure maximum efficiency.

01
Solar Generation (Day)

Solar panels generate DC electricity, immediately powering your facility's active daytime load.

02
Battery Charging

Any excess solar power not used by the facility is directed to charge the Battery Energy Storage System.

03
Grid Outage Support

If the grid fails, the BESS instantly discharges, keeping the facility running without firing up the diesel generator.

04
Peak Discharge (Evening)

During expensive evening grid tariffs, the BESS discharges stored solar energy to power your night shifts cheaply.

05
Smart Grid Sync

If batteries are depleted, the system seamlessly pulls from the grid, ensuring you never face a blackout.

DG Set vs. BESS

Feature Diesel Gen Battery (BESS)
Power Cost ₹18 - ₹25 / unit ₹5 - ₹8 / unit
Switchover Time 10 - 30 seconds Instant (Zero)
Maintenance High (Moving parts) Minimal (Solid state)
Noise & Emissions High Pollution 100% Silent & Clean
Peak Shaving Not Possible Yes

The Hidden Costs of Diesel Generators

For decades, industries have relied on DG sets for backup power. Today, this is the most expensive and polluting way to power a business. Here is why you must pivot to BESS:

  • Exorbitant Fuel Costs: Generating 1 unit (kWh) of power from diesel easily costs ₹18 to ₹25, depending on fuel prices.
  • High Maintenance: Moving parts require constant lubrication, oil changes, and expensive mechanical servicing.
  • Regulatory Bans: Initiatives like GRAP (Graded Response Action Plan) in the NCR frequently ban the use of DG sets to curb severe pollution.
  • Wasted Capital: A DG set sits idle 90% of the time. A BESS works every day by optimizing your peak tariff usage.

The SparkGrid Solution: BESS stores energy at ₹5-7/unit (from Solar) and replaces diesel power that costs ₹20+/unit. The ROI is undeniable.

Who Needs Battery Storage?

Ideal for facilities facing frequent power cuts, strict environmental regulations, or those operating 24/7 with high evening tariffs.

BESS is rapidly becoming the standard for:

  • Hospitals & Cold Storage
  • Hotels & Resorts
  • Precision Manufacturing
  • Telecom Towers
  • Remote Industrial Sites
  • Commercial Real Estate
