Metered savings checks that let lenders tie retrofit EMIs to lower power bills
TL;DR Thriftmeter measures what an energy retrofit really saves in a small hotel, nursing home or school, and hands that number to the lender and the equipment vendor. Repayments are set against the measured saving. Lenders pay per loan verified, and owners get a loan they can trust to pay for itself.
Small commercial buildings run old split ACs, resistive water heaters and pumps that waste power, and the owners know it. They still hold back, because the vendor's savings promise is just that, a promise. Lenders hold back for the mirror reason - they can't see whether the saving that's meant to cover the EMI ever turns up.
The cooling numbers alone make this worth fixing. India's Cooling Action Plan expects national cooling demand to grow about eight times by 2037-38, and says better compressors, optimised operation and retro-commissioning could avoid around 8–12% of the related energy use[1].
Government money is flowing, but mostly to factories. The ADEETIE scheme targets 60 clusters in 14 energy-intensive industrial sectors[2], and a 40-room hotel or a 30-bed nursing home is left to sort out the trust gap alone.
What it does, in regulatory terms: measurement and loan servicing support as a Lending Service Provider to a bank or NBFC. It does not lend, hold funds or set interest rates. Under RBI's Digital Lending Directions 2025, that role needs a written arrangement with the regulated lender[3].
Before a retrofit, Thriftmeter fits clamp-on sub-meters on the circuits that will change and logs four to six weeks of baseline, adjusted for weather and occupancy. It uses the open IPMVP measurement protocol, so the method isn't something we cooked up and a lender's engineer can audit it[4]. After the swap, a monthly statement shows units saved and rupees saved, right next to the EMI.
The lender uses that statement two ways. It can approve the loan with a tenure sized to expected savings, and it can offer a step-down or a tenure extension if the saving falls short for reasons the vendor caused. Vendors who keep missing their numbers get dropped from the programme.
The owner borrows and repays. The bank or NBFC pays Thriftmeter a fee per loan for the baseline, verification and monthly statements, which is cheaper than sending its own engineer. Equipment vendors pay a smaller listing fee, because a verified savings record helps them close sales.
There's no public price for third-party savings verification on small loans in India. My assumption is you test ₹15,000–40,000 per loan plus a monthly fee.
RBI's Digital Lending Directions of May 2025 spell out how a lender can work with a service provider, which makes the partnership contract simpler to draft[3]. SIDBI already runs an End To End Energy Efficiency (4E) scheme and a green finance scheme[5], and ADEETIE funds post-implementation monitoring and verification as a step of its own[2]. Verification is turning into a normal line item.
We found no published number for Indian loans to small hotels, clinics or schools where repayment is tied to measured energy savings.
Adjacent: ADEETIE expects ₹9,000 Cr of investment, including ₹6,750 Cr of MSME lending, in its industrial clusters[2]. That money is for factories, so treat it as proof that lenders will fund efficiency, not as your market size.
Energy-as-a-service firms sell savings to larger buildings[6], and their contract terms aren't public. SIDBI's 4E scheme bundles audit and finance for MSMEs[5]. Equipment vendors offer their own savings estimates and some arrange EMIs through card or consumer-durable lenders, but nobody checks the saving afterwards.
The gap is a neutral meter-and-statement layer that small lenders can buy per loan.
| Difficulty | Moderate (49/100) |
| Starting capital | ₹60 L–1.1 Cr |
| Time to launch | 9–12 months |
The metering is the simple part. The lender is the hard part, because a bank or NBFC has to sign an outsourcing arrangement, put your statement into its credit process and agree what happens when savings fall short. That takes months of compliance review, and you'll need a few hundred verified projects before the data sways a credit committee.
Yes, indirectly. Thriftmeter doesn't lend, but it works as a Lending Service Provider, so the lender's regulator shapes what you can do.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't let AI decide a loan, a step-down or a tenure change. Those are the lender's credit decisions, and a disputed baseline needs a human referee.

Here's what can go south -
This suits a founder from SME lending or energy auditing who can sit across the table from a credit team. If you want to become a lender quickly then look elsewhere, it is a poor fit.
Prove one thing first - that one NBFC will sign an LSP arrangement and route 30 loans through you in six months.
Plan for roughly ₹60 L–1.1 Cr, mostly on sub-meters, site visits and the long lender integration.
You don't need a lending licence, but as a Lending Service Provider you need a written arrangement with a bank or NBFC under RBI's 2025 Digital Lending Directions.
Yes, the IPMVP protocol is used worldwide. Lending service rules differ by country, so check with your financial regulator first.

Thinking about building Thriftmeter or something close to it? The make-or-break work is getting one lender to write your savings statement into its credit process, and I've a few thoughts on how to pitch that. If you need a hand, you know where to find me. Talk to Yash →
