Ontario solar installers were losing deals because of a solvable problem: manually collecting PDF utility bills was taking 3–4 hours per customer and causing 40% of leads to ghost before a proposal could be sent. PeakShift was built to fix this — using the same official Green Button infrastructure used by regulators and utilities themselves.
Company Timeline
First ESPI XML parser built from the ground up. Initial Toronto Hydro API integration begins.
First official Green Button data pull completed in production. 700K+ households reachable.
Only certified solar data recipient in Canada. Hydro One Authorized Data Recipient status granted.
Coverage reaches 2.1M Ontario households across three major utilities.
Total coverage reaches 3.6M+ Ontario households across five utility APIs production-live.
Full 6-utility coverage achieved. London Hydro goes live, bringing total coverage to 4.1M+ Ontario households.
Founder
I founded PeakShift to solve a critical infrastructure gap in Ontario's solar industry: the lack of standardized, automated access to utility energy data was creating friction between installers and homeowners, slowing down clean energy adoption across the province.
I built PeakShift's Green Button integration platform from the ground up — developing ESPI XML parsers, OAuth 2.0 authorization flows, and data normalization pipelines that now serve 4.1M+ compatible homes across Ontario's six major utilities: Hydro One, Toronto Hydro, Alectra Utilities, Hydro Ottawa, Elexicon Energy, and London Hydro.
Our platform transforms raw Green Button data into actionable intelligence — accurate system sizing, TOU-aware ROI projections, and automated proposal generation. We're building the data infrastructure layer that Ontario's clean energy transition requires.
“Ontario has the regulatory infrastructure for clean energy data access. What it was missing was a company that took the time to build a production-grade integration on top of it. That's PeakShift.”
Beyond 2026, PeakShift's goal is to become the canonical utility data access layer for Canada — expanding to BC Hydro, Énergie NB, and Hydro-Québec as Green Button adoption spreads nationally. Every clean energy platform in Canada should be able to access verified utility data through a single compliant API.
Our Commitments
These are not aspirations — they are the specific constraints we operate under by design.
We use real utility data or we do not operate. There are no synthetic profiles or approximation layers in our pipeline — every data point originates from a certified Green Button source.
Green Button means read-only, revocable OAuth access — by design, not by promise. Homeowners can revoke access in one click and we never see their utility password.
Enterprise API integration in 3 days, not 3 months. One SDK, one webhook schema, one support contact who knows your stack. We build developer tooling the way we wish it existed.
Built natively for Ontario's ESPI 1.2 standard, TOU rate structure, and OEB regulatory environment. Not a US product ported across the border.
Production Integrations
Our integrations are production-live or in active testing with Green Button certification, ESPI 1.2 compliance, and official utility credentials.
Ecosystem
PeakShift operates within the regulated Ontario Energy Board framework and adheres to national and international clean energy data standards.
Official Green Button Connect My Data certification — the same standard mandated by US and Canadian regulators for third-party energy data access.
