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. A subsidiary of Halifax-based Emera Inc., it owns generation, transmission and distribution and is regulated by the Nova Scotia Energy and Regulatory Boards Tribunal (formerly the NSUARB). It sits at the retail end of the value chain as a franchise monopoly rather than a competitor in an open market — Nova Scotia has no wholesale market equivalent to IESO or AESO. Its API posture is the sharpest mandate-versus-implementation split in Canadian energy: section 4F of the Electricity Act, added by Bill 145 (SNS 2022, c. 12), legally required NSPI to implement the NAESB ESPI 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 the Green Button Alliance lists NSPI as certified to ESPI v3.3 for Download My Data only, with Connect My Data certification still "planned", and NSPI's own site states the Green Button Marketplace "is currently closed" to third-party applications. There is no developer portal, no published OpenAPI, no OAuth registration and no documented consumer data API — greenbutton.nspower.ca is live but every path redirects to a SAML customer login. By contrast NSPI is genuinely open on market and system data: its OASIS site publishes hourly net energy flow reports as anonymously downloadable CSV going back to 2012. Open market data, closed consumer data, and a statutory mandate whose API half is three years past its deadline.

Nova Scotia Power is profiled on the APIs.io network. Tagged areas include Energy, Canada, Utilities, Electricity, and Energy Retailer.

Nova Scotia Power’s developer surface includes authentication, developer portal, documentation, legal docs, support, engineering blog, product news, and 27 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/nova-scotia-power: open an issue to ask a question, or submit a pull request to add artifacts.
