# Nova Scotia Power

> Nova Scotia Power Incorporated (NSPI) is the investor-owned, vertically integrated regulated electric utility serving roughly half a million customers across Nova Scotia, Canada, and a subsidiary of Halifax-based Emera Inc. It is under a direct statutory obligation — section 4F of the Electricity Act, added by Bill 145 (SNS 2022, c. 12) — to implement the NAESB ESPI (Green Button) standard and be certified by the Green Button Alliance to both "Connect My Data" and "Download My Data" on or before April 1, 2023. As of July 2026 only Download My Data is certified; Connect My Data — the half that is an actual API — is still "planned", and Nova Scotia Power's Green Button Marketplace is closed. Open market data, closed consumer data, and a mandate three years past its deadline.

Generated by API Evangelist from the Nova Scotia Power APIs.json profile. Method: generated. Date: 2026-07-27.
Nova Scotia Power does not publish an llms.txt of its own (https://www.nspower.ca/llms.txt returns HTTP 404).

## What an agent needs to know first

- There is **no API**. No OpenAPI, Swagger, GraphQL, AsyncAPI, gRPC or MCP surface exists on any Nova Scotia Power host. `/openapi.json`, `/swagger.json` and `/api-docs` return HTTP 404 on www.nspower.ca, redirect on oasis.nspower.ca, and 302 to a SAML login on greenbutton.nspower.ca. No `api`, `developer`, `developers`, `docs` or `data` subdomain resolves.
- There is **no developer portal, no signup, no sandbox and no API key**. The Green Button Marketplace is closed and the third-party registration form Nova Scotia Power links to returns HTTP 404. There is no route a developer can complete today.
- **Consumer energy data is closed.** Download My Data is certified (ESPI v3.3) but it is a file download for a logged-in account holder behind SAML 2.0 SSO at `accounts.nspower.ca` (LoginRadius). No third party can obtain a customer's usage data programmatically. Connect My Data — the OAuth 2.0 authorization flow that would allow it — is not certified and not deployed; `https://greenbutton.nspower.ca/oauth/authorize` 302s to the customer login page.
- **Market and system data is genuinely open, as bulk files.** `https://www.nspower.ca/oasis` publishes monthly reports, forecasts, system reports and messages, distribution hosting capacity, standards and codes, and wholesale market documents as CSV, HTM and PDF — anonymously, no login, no licence click-through. Hourly net energy flow reports for the NS–NB interconnection and Onslow South run from 2012 through 2025. Verified anonymously: the 2025 NS–NB tie CSV returned HTTP 200, 253,453 bytes.
- **Do not treat vendor infrastructure as an API.** `outagemap.nspower.ca` serves real JSON (KUBRA outage-map platform) and `https://www.nspower.ca/api/default/` returns an OData 401 (Progress Sitefinity's built-in CMS endpoint). Neither is documented or advertised by Nova Scotia Power; both are recorded as observations and deliberately excluded from the APIs.json profile.

## APIs

None. `apis[]` in the APIs.json profile is empty, and that is the correct, honest outcome — nothing was invented to fill the gap.

## Data

- [OASIS](https://www.nspower.ca/oasis): the open market and system data surface. Anonymous bulk files.
- [Monthly Reports](https://www.nspower.ca/oasis/monthly-reports): hourly net energy flow reports (NS–NB interconnection, Onslow South) as CSV and HTM, 2012–2025.
- [System Reports and Messages](https://www.nspower.ca/oasis/system-reports-messages): including the posted system average loss factor.
