The problem, broken down

Who it hurts
Residents, businesses and software tools that use Electricity Maps to estimate the carbon in Newfoundland and Labrador's power.
The moment
When a carbon tool shows the island's power as far dirtier than its mostly hydro supply.
What people do today
Electricity Maps falls back on a default value, and the province's generation data sits in monthly PDF reports.
Why it's unsolved
There is no real-time feed splitting island generation from imports from Labrador, and the monthly figures are only in PDFs.
What solved looks like
A script that pulls monthly generation by source from NL Hydro's PDF reports into a CSV from 2018 to the latest month, and a pull request to Electricity Maps adding a source-based fallback power mix for the Newfoundland zone, with the method written down.

Evidence

Every claim is tied to the source it comes from
Electricity Maps issue #6502: Newfoundland CO2 intensity ↗
  1. 1The issue says Newfoundland's CO2 intensity is much lower than the default 461 shown for its power deliveries to Nova Scotia, since supply is mostly hydro and wind.
  2. 2A commenter said there is no real-time data showing how much is generated on the island versus brought in from Labrador, and estimated about 76 g CO2eq/kWh for 2023 from NL Hydro's monthly report.
  3. 3A project member replied that a fallback mix of power sources should be added rather than a single CO2 figure.
Public Utilities Board: NL Hydro energy supply monthly reports ↗
  1. 4On 2026-10-09 the Public Utilities Board page listed NL Hydro's energy supply monthly reports as PDF files only; the newest, for August 2026, was filed on 2026-09-17.
