From feasibility through PPA signing, financial close, construction and COD — TPC brings manufacturing, Tier-1 procurement, engineering and EPC delivery under one commercial structure.
Every panel, inverter and BESS cell we specify clears Tier-1 bankability. That means the lender's independent engineer's (IE) review doesn't push you back into value-engineering three months before financial close.
We price the project, we sign the guarantee, we carry the execution risk. Your model stops running on "EPC contingency + overrun reserve" and starts running on a signed contract number.
MV/HV substations, transformers and utility witness testing are part of our scope — not a separate sub-EPC contract with its own schedule and liability wall. One schedule, one accountable party, one interface with the utility.
We own the module manufacturing line. That takes six weeks of lead-time volatility out of the financial model. For third-party equipment, we're buying at EPC-scale frequency, which smooths price and slot availability.
Long-term O&M with performance-ratio and availability guarantees is drafted alongside the EPC — not bolted on after commissioning when the contractor has already left the site.
Technical reports, yield studies, warranty stacks, as-builts and performance data are produced in the format lenders and IEs expect. No weeks of document reformatting during DD.
Panels arrive late, but the schedule absorbs it. Inverters arrive late, and the schedule still absorbs it. What kills the COD date is the HV substation — the transformer that didn't ship, the protection relay the utility rejected, the metering class that needs a second witness test. We bring that scope in-house with Chint as our grid-equipment supplier and handle utility coordination from day one.

Yield study, single-line diagrams, protection relay settings, grid-code compliance, independent-engineer responses — TPC produces lender documentation in the format that travels cleanly through IE review. It is not an afterthought we ask an external EPC to produce for us.
We work with developers at multiple stages — from pre-PPA feasibility to post-NTP construction handover. The earlier we come in, the more room we have to optimise LCOE.
You have a site and a target PPA price. We run a feasibility study — resource, yield, capacity, LCOE bands — to tell you whether the site is worth developing and what size envelope makes sense.
2–4 weeksYou're bidding into a tender or negotiating a bilateral PPA. We produce an indicative fixed-price EPC envelope and module supply commitment you can build your bid around.
3–6 weeksYou've won the PPA and you're heading into lender DD. We produce the full technical stack the IE needs, sign the binding EPC, and commit procurement slots.
8–16 weeks (parallel to DD)We mobilise, deliver, construct, commission and energise. Performance-ratio testing, utility witness testing, as-built handover — all before the O&M clock starts.
36–72 weeks for utility-scaleWhen COD is money, every day of slippage is priced in. Our developer counterparties don't pay slippage — because we plan not to generate any.
Five-hundred MWp delivered. Seventeen countries. 98% on-time closure against original COD — audited in our independent engineer reports, not our marketing deck.
"The moment I knew we'd picked the right EPC was when their engineering team flagged two issues with our own independent engineer's study — and they were right on both counts."
Send us the site, the target capacity, and the stage you're at. We'll come back with the right engagement structure — feasibility, indicative EPC, or binding proposal.
