Grid Freedom

Decouple from
volatile tariffs.

By pairing solar with advanced Battery Energy Storage, you stop relying on a fragile utility grid and start controlling your own energy costs—permanently.

How It Works

From first data point to
continuous optimisation.

Every WattSpace engagement follows the same four-step process, engineered to ensure your system performs at its absolute peak.

Design Simulation

Integration Build
Step 2 · Execution

Integration & Build

We manage procurement, coordinate EPC partners, oversee installation, and integrate solar, BESS, DG set, and EV charging into one cohesive energy system.

  • Best-in-class tier-1 hardware
  • Industry-leading equipment guarantees
Monitoring Platform
Step 3 · Visibility

Monitoring Platform

Every sensor connected to our analytics platform. Track real-time generation, storage state-of-charge, grid draw, and actual savings by tariff period.

  • Cloud-based central dashboard
  • Live degradation and SOC tracking
Continuous Optimisation
Step 4 · Automation

Continuous Optimisation

Charge/discharge parameters update continuously as our engine learns your site. Your system improves with every cycle, adapting to evolving load patterns and tariff changes.

  • Automated peak-shaving dispatch
  • Adaptive response to utility tariff shifts

FAQs

Do you offer CAPEX or OPEX (BOOT) financing models?
Yes, we offer flexible financing options including CAPEX, BOOT (Build-Own-Operate-Transfer), and Energy-as-a-Service (EaaS) models. Our team can help determine the most suitable structure based on your energy requirements, budget, and business objectives.
How do you reduce my electricity bill?
Most C&I businesses overpay because they draw from the grid at exactly the wrong times — during peak demand slots when tariffs are highest. We model your consumption pattern, design a storage system that charges during cheap off-peak hours or from your solar, and discharges precisely when your bill exposure is highest. The result is a significant and sustained reduction in both your energy and demand charges.
What is demand charge management and why does it matter?
Your electricity bill has two major components — the units you consume and your peak demand. Demand charges are calculated on the highest load your site draws in any given billing period, even for just a few minutes. For HT consumers this is often one of the largest single line items on the bill. BESS allows us to clip those peaks, reducing your sanctioned demand and the charges that come with it — sometimes accounting for more than half your total savings.
Do I need solar to benefit from BESS?
No — though the combination is significantly more powerful. Without solar, BESS still creates value through tariff arbitrage, charging at low off-peak rates and discharging at peak. With solar, the BESS charges from free generation, which dramatically improves the economics and shortens the payback period.
What kind of savings can I expect?
It depends on your tariff structure, consumption pattern, and connection type. For a typical HT C&I site in Tamil Nadu, our analysis has shown bill reductions in the range of 30–50%, with payback periods of 2.5–5 years. For LT sites the primary value driver is often energy independence rather than demand management — reducing exposure to an unreliable and capacity-constrained grid. We model every site individually before making any claim — we do not use generic benchmarks.
Do you work with LT customers?
Yes. Grid congestion is making it increasingly difficult for LT businesses to get sanctioned load approvals — meaning growth is constrained not by ambition but by infrastructure. For LT customers, BESS combined with solar provides a practical path to energy independence: generating and storing your own power, reducing grid dependency, and protecting your operations from supply constraints and outages. We work with LT C&I businesses across a range of sectors and size the solution to match your load and budget.
