About Enerstat
Consulting engineers & energy management services
Incorporated in 2015, Enerstat Solutions is a Kolkata based electrical engineering company specialised in the design, analysis and implementation of indoor and outdoor substations from 11kV to 132kV for industrial, utility and infrastructure applications. We combine strong domain knowledge with advanced engineering software and digital technologies to deliver safe, efficient and future-ready electrical networks.
Engineering integrity
Every design is defensible against IEC, IEEE, IS and CEA requirements — no shortcuts that shift risk to the client.
Sustainability
Improving energy efficiency lowers both operating cost and environmental impact. Both matter, in that order of urgency.
Value engineering
Value is achieved by improving performance while reducing cost across the whole equipment life cycle.
Partnership
Reliable project support from concept design through commissioning, with one accountable engineering team.

Power quality
Harmonics you can see before you pay for them
Distorted current stresses transformers, cables and capacitors and inflates demand charges. We measure the waveform, model the network and specify filtering and correction so the supply returns to a clean sinusoid.
From 11kV distribution to 132kV substations — engineered for uptime, safety and efficiency.

Steel & Foundry132kV substation and 33kV distribution for a growing foundry
Utkal Moulders Pvt. Ltd, Rourkela
- Challenge
- The foundry needed a dedicated 132kV intake with 33kV distribution to support melting furnace expansion without compromising statutory approval timelines.
- Outcome
- Approval-ready drawings for the electrical inspectorate, optimised equipment ratings and a distribution network scalable for the next furnace bay.
8-10% lower implementation cost through value engineering
Food & Beverages125-meter energy monitoring plus active harmonic filtering
Bengal Beverages Ltd (Coca-Cola), Dankuni
- Challenge
- High harmonic distortion from variable speed drives on bottling lines, with no visibility of section-wise energy consumption.
- Outcome
- Line-wise consumption benchmarking, improved power factor and distortion brought within acceptable limits at the PCC.
10-15% reduction in running energy cost potential
SteelEnergy management system across 400 x 33kV feeders
Jindal Steel Ltd, Raigarh
- Challenge
- A large integrated plant needed unified accounting of energy across hundreds of 33kV feeders spread across multiple substations.
- Outcome
- Department-wise energy accounting, deviation alerts and a factual basis for demand-side management decisions.
Measurable demand-charge reduction from peak visibility
Engineering & MetalsHybrid 400A active harmonic filter supply & commissioning
