Lead credential
Lead developer of the 5 GW Wind–Solar–BESS Hybrid DPR for KREDL, Karnataka — the largest hybrid programme of its kind in India.
Services
The full project lifecycle
Most consultancies own one slice. We cover concept through asset management, so decisions taken at the concept stage are still owned when the plant is commissioned.
02
Design — Engineering & yield
Energy yield in PVsyst and WAsP, plant layout, cable sizing and earthing, evacuation and substations 33 kV to 400 kV, hybrid and floating solar design, vendor design review.
03
Deliver — Tendering, PMC & ESHS
EPC tendering and contract enforcement, site supervision by senior members, quality assurance, ISO and ESHS discipline, commissioning and punch-list closure.
04
Optimise — Performance & diligence
O&M planning, underperformance diagnosis, pre-investment and operational asset diligence, acquisition support, tender and bid optimisation.

Six of eleven mandates shown.
We build projects. We also independently evaluate projects. That is unusual, and it is the reason our diligence finds what a desk review does not.
Methods
- Consumption Matching for Capacity Evaluation
- Micrositing — WAsP / PVsyst
- Generation & grid evaluation
- O&M effectiveness
- Financial viability with SWOT

The firm
The people behind the mandate
Terrastrom Solutions is built around a group of practising engineers rather than investors or career consultants. Each has an independent career in the power and renewable sectors behind them, and each contributes directly to the work.
Those careers were built at L&T, Tata Power Solar, Tata Consultancy Services, SunEdison, Vestas, NEG Micon, Suzlon, Kenersys, Bosch, IISc, Exide and BOC Gases — across India, South-East Asia, Sub-Saharan Africa and the Gulf.
A lean core, engaged per mandate
Every mandate is led personally by a senior member of the group, who stays accountable from the first site visit to final handover, and is staffed for the scope in hand.
Both sides of the table
We build projects and we independently evaluate them. How we design informs what we look for in diligence, and the reverse.
Delivered with our associates
Specialist civil, structural, substation and software scope comes in from long-standing associate practices — coverage without overhead.
