Engineering outcomes, documented

Each project below states the client, the challenge, the engineering solution, the outcome and the savings achieved or made available.

Steel & Foundry

132kV 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.
Solution
Complete design and engineering of the indoor/outdoor substation, protection philosophy, earthing and 33kV distribution, validated through ETAP load flow, short circuit and relay coordination studies.
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 & Beverages

125-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.
Solution
PC-based energy monitoring across 125 meters combined with active harmonic filters sized from measured harmonic spectra.
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

Steel

Energy 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.
Solution
Architecture, integration and commissioning of a plant-wide energy management system consolidating 400 feeders into a single reporting platform.
Outcome
Department-wise energy accounting, deviation alerts and a factual basis for demand-side management decisions.

Measurable demand-charge reduction from peak visibility

Engineering & Metals

Hybrid 400A active harmonic filter supply & commissioning

Primetals Technologies, Kolkata

Challenge
Sensitive automation loads were exposed to harmonic pollution and poor power factor at the LV bus.
Solution
Supply and commissioning of hybrid 400A active harmonic filters with detuned reactive compensation, engineered from a measured power quality survey.
Outcome
Stable voltage profile, compliant THD levels and reduced nuisance tripping of drives.

Avoided penalty charges and improved equipment life

Water Management

Automation of a public water pumping station

Simplex Infrastructure (PHED)

Challenge
Manual pump operation across a public health engineering scheme caused inconsistent delivery and energy waste.
Solution
Design services for pumping station automation covering control philosophy, instrumentation, panel design and SCADA interfacing.
Outcome
Unattended pump sequencing, reduced dry-run risk and auditable operating data for the utility.

Lower specific energy consumption per million litres pumped

Institutional

Auto-synchronising of 2 x 250kVA DG sets with mains

Indian Association for the Cultivation of Science

Challenge
Critical research laboratories required seamless changeover between mains and captive generation.
Solution
Design of the auto-synchronising scheme, load sharing logic, protection and interlocks for two 250kVA DG sets.
Outcome
Uninterrupted supply to sensitive loads with the lowest possible downtime during grid disturbances.

Reduced diesel run-hours through optimised load sharing
