Engineering the energy transition at utility scale
NEWATT has delivered power system studies and detailed electrical engineering for solar PV plants up to 500 MWp, onshore wind farms and RE-hybrid projects combining solar, wind and battery storage across India and Malaysia.
Our team covers the full technical scope from resource assessment and yield modelling through collector system design, substation engineering, grid-code compliance studies and commissioning support — keeping the entire design under one accountable team.
What this sector involves
A utility-scale renewable plant has to navigate a chain of electrical engineering decisions before a single panel or turbine is installed — resource assessment drives technology selection, yield modelling sets the financial basis, and the collector system, pooling substation and grid connection have to be designed to actually deliver the modelled output to the network.
On the grid-compliance side, Indian STU and CTU interconnection, UK G99/G5/5 and Malaysian TNB/SESB grid codes each impose specific requirements for voltage ride-through, frequency response, power quality and protection — all of which need studies submitted and accepted before energisation is approved.
NEWATT has delivered every part of this chain — from bankable energy yield reports and PVsyst modelling through to detailed electrical drawings, ETAP/PSCAD studies and relay setting sheets for commissioned plants across India, Malaysia and the UK.
Typical scope for Renewables
- Solar PV up to 500 MWp
- Onshore wind farms
- RE-hybrid & co-located BESS
- Pooling substations 33/220 kV
- STU & CTU grid compliance
- LVRT, HVRT & FRT verification
- Energy yield & PVsyst modelling
- SCADA & grid integration
What NEWATT delivers for renewables
Energy yield & resource assessment
Bankable energy yield reports, PVsyst modelling and P50/P90 estimates for solar PV, wind resource analysis and long-term generation forecasting — prepared to the level lenders and EPCs require for investment decisions.
Collector system design
MV and HV collector network design — cable sizing, routing, feeder topology, protection and reactive power compensation — for solar PV plants, wind farms and hybrid sites, sized for the actual generation profile rather than a peak-only assumption.
Pooling substation engineering
Complete pooling substation electrical and civil engineering at 33 kV, 66 kV, 132 kV and 220 kV — layouts, SLDs, protection, earthing, cable engineering and civil structures — from concept to issued-for-construction drawings.
Grid compliance studies
Load flow, short circuit, LVRT/HVRT, frequency response, harmonics and power quality studies to Indian CEA, UK G99/G5/5 and Malaysian TNB/SESB grid codes — structured to meet what the network operator actually needs for a connection approval.
Studies that unlock grid connection
PSCAD & EMT studies
Inverter-level EMT studies in PSCAD for LVRT, HVRT, frequency response and power oscillation damping — required by many grid operators for plants above a threshold capacity, and often the critical path item for connection approval.
Protection & relay coordination
Complete protection coordination from the grid interface down to the string combiner level, including generator protection, feeder protection and differential protection for pooling transformers — with relay setting sheets ready for commissioning.
BESS integration studies
Power system studies and electrical engineering for battery energy storage co-located with renewable generation — PCS integration, grid-code compliance, LVRT/HVRT and frequency response for hybrid plants operating as a single generating unit.
Reactive power & voltage studies
Reactive power capability assessment, voltage profile optimisation and reactive power compensation design for plants connecting at high-voltage busbars where voltage band and power factor requirements are tightly specified by the network operator.
