I Said This in 2021. India is Just Getting There Now.

A 4-Year Head Start Nobody Noticed
On 13 March 2021, I wrote to Shri R K Singh, Union Minister of Power, with a detailed proposal.
I called it a Conceptual Framework for Smart Energy & Emission Monitoring — or SEEM.
The core idea was simple but radical: every household appliance in India should carry an IoT sensor that continuously monitors its energy consumption, relay that data to a Smart Electric Meter in the home, which in turn relays it to the DISCOM — appliance by appliance, unit by unit, in real time.
Efficient appliances would earn Carbon Credits. Inefficient ones would earn Carbon Debits. The net balance would determine your electricity tariff. Rooftop solar would further boost your Credits. The result: 290 million Indian households plugged into the global carbon economy.
This week, the Economic Times carried an article headlined: "Consumers to Soon Get Data on Power Generated, Used."
I felt a familiar mix of satisfaction and impatience.
What the ET Article Announces
The article describes India's push — through the RDSS scheme and Advanced Metering Infrastructure — to finally give consumers real-time, transparent data on how much power they are generating and consuming. Smart meters are being rolled out. Two-way communication between homes and DISCOMs is becoming a reality. Time-of-Day tariffs are being introduced, with solar hours priced at a 20% discount to incentivize clean consumption.
This is excellent news. But it is also, essentially, one piece of a larger puzzle I described five years ago.
Where We Align
In 2021, I proposed that Smart Meters relay consumption data to DISCOMs. The ET article announces exactly that — household-level data flowing to utilities in real time.
In 2021, I proposed Time-of-Day incentives linked to solar generation, so that rooftop solar owners get rewarded through their tariff. The PM Surya Ghar scheme and ToD pricing are now doing precisely that.
In 2021, I proposed replacing all household meters with Smart Meters by April 2024. We are delayed — roughly 24 million have been installed as of mid-2025 against a target of 250 million — but the direction is right.
In 2021, I proposed Carbon Finance as the underlying funding model for energy efficiency at the household level, drawing from the EESL/GRAM Ujala experience of using carbon credits to subsidise LED bulbs in rural Bihar. That model of carbon-backed incentivization is now finding its way into broader climate finance conversations across South Asia.
Where We Are Still Behind — My Unfinished Agenda
Here is where I must be blunt.
The ET article, and the RDSS rollout, speak of household-level data. Smart meters measure total consumption at the connection point. That is necessary — but it is not sufficient.
My 2021 proposal went one level deeper: appliance-level monitoring.
Each refrigerator, air conditioner, washing machine, and television should carry a BEE-certified IoT sensor that reports its individual consumption. Not the household total — each individual device. This data should flow into the Smart Meter, and from there to the DISCOM, tagged to the specific appliance.
This distinction matters enormously. Here is why:
A household may have a Smart Meter showing 400 units consumed in a month. But which appliance is responsible? An old 5-star AC running 8 hours a day? A malfunctioning refrigerator with a worn compressor? A neighbour's load running through a shared connection? You cannot know from the aggregate figure.
Appliance-level data enables:
- Targeted replacement subsidies — EESL can identify homes with inefficient ACs or refrigerators and offer replacements through the ESCO model, financed by carbon credits
- Manufacturer accountability — BEE can track real-world efficiency ratings versus lab-certified ratings, and enforce compliance
- Dynamic carbon accounting — each appliance's Carbon Credit or Debit balance can be computed monthly, creating a granular household carbon ledger
- Peer benchmarking — consumers can compare their appliance-level footprint against neighbourhood averages
This is not technologically difficult. IoT sensors cost less than ₹200 per unit today. Any appliance manufacturer integrating a Wi-Fi chip for a "smart home" feature is already halfway there. What is missing is a mandate — the same kind of phase-wise mandate I proposed in 2021, modelled on the BS IV to BS VI emission norm transition for vehicles.
The Four-Phase Mandate I Proposed — Still Valid
In 2021, I suggested that appliance manufacturers be required, in four phases:
- April 2022 — All new models submitted for BEE certification must include IoT sensors
- April 2024 — All new production must include IoT sensors
- April 2026 — Old stock without sensors cannot be sold
- April 2028 — Complete market transition; retrofit programme for existing appliances
We are at April 2026. Had this been implemented, we would today have a generation of sensor-equipped appliances entering Indian homes. We would have three years of real-world consumption data. We would have a functioning household carbon ledger covering tens of millions of homes.
We do not. We are still at the starting line.
The good news: it is not too late to begin. The four-phase roadmap can be restarted from today, with a 2026–2030 window.
The Larger Vision: Carbon Finance Inside 290 Million Homes
The GRAM Ujala programme showed us something important. When you attach carbon finance to energy efficiency — even something as simple as an LED bulb — you can fund rural access to clean technology without government subsidy. The carbon credit pays for the subsidy. The rural consumer gets a ₹10 bulb. The DISCOM gets lower peak demand. The planet gets fewer emissions.
That logic scales.
Imagine a India where:
- Every home has a Smart Meter feeding real-time data to the DISCOM
- Every appliance has an IoT sensor feeding the Smart Meter
- Every household has a monthly Carbon Credit/Debit ledger, computed automatically
- Rooftop solar adds to your credits; an inefficient old AC adds to your debits
- Your net balance determines your electricity tariff for the next billing cycle
- Carbon offsets from millions of efficient homes are aggregated and sold in global voluntary markets
- Proceeds fund further subsidies for rural electrification, LED distribution, and rooftop solar
This is not a fantasy. Every component of this system either exists or is being built. Smart meters — underway. IoT appliance sensors — technically ready. Carbon markets — growing. BEE certification — established. DISCOM data infrastructure — being upgraded under RDSS.
What is missing is integration — the policy will to connect these dots into a single, coherent system.
A Note on Timing
When I wrote to Shri R K Singh in March 2021, I noted: "This is only a Conceptual Framework whose details are not difficult to work out."
Five years later, India is working out the details — one piece at a time, with significant delays. Smart meters are behind schedule. Appliance sensors have not been mandated. The carbon credit linkage at the household level remains unattempted.
I do not say this to criticise. India's energy transition is complex, multi-stakeholder, and politically demanding. The reforms that have happened — RDSS, PM Surya Ghar, ToD tariffs — are real and meaningful.
But complexity is not an excuse for indefinite delay on ideas whose time has clearly come.
The ET article this week is encouraging. It tells me the direction is right.
The pace, however, must accelerate.
What I Ask For
I ask the Ministry of Power and BEE to consider:
- Mandate IoT sensors in all new BEE-certified appliances from 2026, with a four-phase timeline to 2030
- Integrate appliance-level data into the RDSS Smart Meter architecture, so that each meter can receive and relay per-appliance consumption
- Link the household carbon ledger to electricity tariffs, creating a direct financial incentive for energy efficiency
- Establish a voluntary carbon offset programme for efficient households, with aggregated credits sold in global markets and proceeds reinvested in rural energy access
None of these require new technology. They require coordination, mandate, and will.
