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.
