Peakmoor

AC pre-cooling that moves office and mall load out of discom peak hours

Climate Tech Enterprises IoT

TL;DR Peakmoor fits a small controller to the chillers and air handlers of mid-size offices, malls and hotels, then cools the building harder before the evening peak and coasts through it. Building owners pay from their time-of-day savings, and discom demand-response incentives are the second income line.

The problem

India met a record 250 GW of demand on 30 May 2024[1], and the hot-weather peak is driven heavily by cooling. Since April 2024, commercial and industrial connections above 10 kW were due to move to time-of-day tariffs, with peak-hour energy priced above the normal rate[2]. Most mid-size buildings still run their AC on a fixed schedule set by the facility manager years ago, so they pay the peak premium every single afternoon.

And the discoms that want them to cut load during emergencies? They mostly send an SMS and hope.

The idea

First things first - Peakmoor is a retrofit and not a new building management system. A gateway reads chiller power, supply-water temperature and a handful of zone sensors. A model learns how fast each floor warms once cooling is throttled. On hot days it pre-cools the building during cheaper hours, then trims chiller output in the peak window while keeping zones inside an agreed comfort band. When a discom calls a demand-response event, Peakmoor sheds the agreed kilowatts automatically and logs the proof.

The seed was a general platform for shifting demand across a city. I narrowed it to one load that a single buyer controls. Building thermal mass is a cheap battery that is already paid for, and a Purdue and Berkeley Lab study cut cooling-related peak demand in small offices by 30% with pre-cooling[3]. Indian buildings, climates and tariffs differ, so treat that figure as a direction and not a promise.

Who pays

The payer is the building owner or the facility-management firm running the site. They pay a monthly fee per site, ideally priced as a share of verified peak-hour savings so the first year costs them nothing upfront. Discoms that run demand-response programmes pay incentives to participants for curtailing load[4], and Peakmoor can enrol buildings and keep a share. I found no public figure for typical payouts per event.

Why now

Time-of-day pricing for larger commercial connections became mandatory on paper from April 2024[2], and smart meters make the price signal visible. A large private utility announced a Mumbai programme in 2023 aiming at 6,000 large commercial and industrial customers and 200 MW by summer 2025[4]. Discoms now have a reason to buy flexible load, and buildings have a bill line that shows it.

Market signal

There is no published figure for India's commercial demand-response market. The narrowest public signal is that utility's Mumbai target of 6,000 large C&I customers and 200 MW of peak reduction[4]. An earlier Delhi pilot linked over 160 commercial and industrial buildings and shed about 11.5 MW on request[5]. The national peak of 250 GW[1] is adjacent context for the grid, and it is not a market for one startup.

Who's already doing this

A US demand-response software firm runs the platform behind that utility's programmes, but it sells to the discom and leaves the building side to customers[4]. A global controls maker installed automated demand response for a private Delhi distributor in 2015[5]. Large building management system vendors can schedule pre-cooling, but mid-size buildings rarely pay for that tuning. The gap is a per-building service that does the thermal tuning and the enrolment together.

How hard is it?

Difficulty Moderate (38/100)
Starting capital ₹60 L–1.2 Cr
Time to launch 6–9 months

The control logic is well understood. The hard part is physical access, because every chiller plant is wired differently and no facility manager lets a startup touch the controls until comfort complaints are ruled out. What wins the second site is proving savings against a credible baseline (not a cherry-picked day).

Licences and approvals

No sector licence here. Peakmoor controls a customer's own equipment, so tariff rules and contracts matter more than permits.

  • State time-of-day tariff order, read before you promise any saving, since each state commission sets its own peak windows and rates[2].
  • Discom demand-response terms in writing before you count incentive revenue, as in the Mumbai utility programme[4].
  • DPDP Act compliance before launch if occupancy data can be tied to named staff, so keep it aggregated[6].
  • Company or LLP registration with the MCA, GST once over the threshold and a Shops and Establishments registration for your office.

Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.

How AI can power this business

  • Thermal models per floor. Learn how fast each zone warms when chillers are throttled, so the pre-cooling plan fits the building and not a generic curve.
  • Day-ahead plans. Use weather forecasts and the tariff window to set tomorrow's pre-cooling start time, which saves the facility manager a daily guess.
  • Savings baselines. Build a fair baseline from past days with similar weather and occupancy, so the monthly savings report holds up in front of the owner.
  • Fault spotting. Flag a chiller or air handler that uses more power than its pattern suggests, often before a comfort complaint comes in.

Don't hand AI full control of the plant. Keep hard comfort limits and a manual override in place, because one bad model call can heat up a boardroom.

Biggest risks

Here's what can go south -

  • Comfort complaints. One hot boardroom during a peak window can get the controller unplugged for good.
  • Thin tariff gap. If a state sets a small peak premium then savings may not cover the fee at smaller sites.
  • Discom programmes stall. Demand-response schemes depend on regulators and can pause or pay late.

Our take

I think this suits a founder who has worked in HVAC commissioning or facility management and can talk to a chief engineer as a peer. If you're a pure software team then it's a poor fit. First prove one thing on three buildings in a single discom area - a verified peak-hour cut of 15% or more for a full month with no comfort tickets.

Questions founders ask

Plan for roughly ₹60 L–1.2 Cr, mostly for engineers, controllers and the first pilot sites.

Do I need a licence to start a building demand response business in India?

No sector licence. You need the usual company registration and GST, the state tariff order and the discom's programme terms in writing.

Can I start an AC pre-cooling business in another country?

Yes, wherever commercial buildings pay peak-hour tariffs or utilities pay for demand response. Check your local tariff structure first.
