    This stacked column graph shows GHG emissions in PEI by sector every five years from 1990 to 2017 in MT of CO2e. Total GHG emissions have decreased in PEI from 1.9 MT of CO2e in 1990 to 1.8 MT of CO2e in 2017.

Energy Production

Crude Oil

  • Prince Edward Island (PEI) does not have any commercial crude oil production.
  • Canada’s first offshore well was drilled 12 kilometres (km) south of Charlottetown in Hillsborough Bay in 1943. The well was dry.

Refined Petroleum Products (RPPs)

  • There are no refineries in PEI.

Natural Gas/Natural Gas Liquids (NGLs)

  • There is no natural gas or NGL production in PEI. PEI has some natural gas reservoirs, but only 20 exploratory wells have been drilled on and around the province to date.
  • In November 2018, Corridor Resources Ltd. announced that it was decommissioning two exploration wells near Cavendish. The wells never produced any commercial quantities of natural gas.


  • In 2018, PEI generated about 0.6 terawatt hours (TW.h) of electricity (Figure 1), which is approximately 0.1% of total Canadian production. PEI has a generating capacity of 376 megawatts (MW).
  • Roughly 98% of power generation on PEI is from wind farms. As of 2018, there were 203 MW of installed wind capacity on PEI (Figure 2). However, the majority of electricity consumed in PEI comes from New Brunswick, which generates electricity from a mix of nuclear, fossil fuels, and hydroelectricity.
  • PEI’s largest wind farm is Engie’s West Cape Wind Park with a capacity of about 100 MW.
  • Diesel and oil-fired facilities are used to meet periods of peak power demand and during emergencies when wind generation or off-island imports are interrupted. Such facilities accounted for less than 1% of PEI’s total energy needs in 2018.
  • The majority of PEI’s electrical generation, transmission, and distribution is provided by Maritime Electric Company Ltd., (Maritime Electric), a wholly-owned subsidiary of Fortis Inc.
  • PEI Energy Corporation is a provincial Crown corporation whose mandate is to develop and promote the development of energy systems, and currently is involved in the generation, transmission, and distribution of energy. The Crown corporation operates wind farms at Elmira (30 MW), Hermanville (30 MW), North Cape (13.6 MW), and is planning a 30 MW expansion of the Eastern Kings Wind Farm. It finances renewables initiatives such as the Wind Energy Institute of Canada Renewable Energy Park in the province.
  • Some thermal generating facilities are owned by a municipal utility in Summerside. Eight wind farms are owned by a small number of independent companies, including a municipal utility, an independent power producer, and a Crown corporation.

Energy Transportation and Trade

Crude Oil and Liquids

  • There are no refineries in PEI.

Natural Gas

  • PEI is not connected to any natural gas pipeline systems.

Liquefied Natural Gas (LNG)

  • There are no current or proposed LNG facilities in PEI.


  • PEI is a net importer of electricity, with net interprovincial and international electricity inflows of 0.8 terawatt hours (TW.h) in 2018.  PEI sources approximately 60% of its electricity from New Brunswick. Electricity is transmitted between provinces by four subsea cables under the Northumberland Strait.
  • The Interconnection Upgrade Project was completed and placed in service in 2017. The project increases transmission capacity between New Brunswick and PEI by adding two new 180 MW subsea cables. The original two cables linking PEI and New Brunswick were installed in 1977 with a capacity of 100 MW each.
  • Power is distributed around the island on about 6 000 km of transmission and distribution power lines which are owned and operated by Maritime Electric.
  • The PEI Energy Corporation also owns transmission facilities in Prince County to connect its North Cape operations and other generators to the Maritime Electric grid.

Energy Consumption and Greenhouse Gas (GHG) Emissions

Total Energy Consumption

  • End-use demand in PEI was 27.4 (PJ) in 2017. The largest sector for energy demand was transportation at 42% of total demand, followed by industrial at 25%, residential at 23%, and commercial at 10% (Figure 3). PEI’s total energy demand was the 10th largest in Canada, and the 11th largest on a per capita basis.
  • RPPs were the largest fuel type consumed in PEI, accounting for 15.9 PJ, or 59%. Electricity and biofuels accounted for 7.7 PJ (28%) and 2.3 PJ (8%), respectively (Figure 4).

Refined Petroleum Products

  • Gasoline consumed in PEI is primarily produced at the Irving Oil Refinery in Saint John, New Brunswick.
  • The Irving Oil Terminal in Charlottetown receives gasoline, diesel, heating oil, and kerosene via ship. RPPs are then distributed throughout the island by truck.
  • Total 2018 demand for RPPs in PEI is estimated at 7.7 thousand barrels per day, or less than 0.5% of total Canadian RPP demand.
  • PEI’s per capita RPP consumption in 2018 was 2 961 litres (19 barrels), or 3% below the national average of 3 038 litres per capita.
  • PEI’s Regulatory and Appeals Commission regulates provincial prices for gasoline, diesel, furnace oil, and propane. The Commission schedules price adjustments on gasoline, diesel, and furnace oil every Friday. Propane prices are set every second Friday.

Natural Gas

  • A small amount of compressed natural gas is trucked into PEI for industrial use.


  • In 2017, annual electricity consumption per capita in PEI was 14.2 megawatt hours (MW.h). PEI ranked 7th in Canada for per capita electricity consumption and consumed 2% less than the national average.
  • PEI’s largest consuming sector for electricity was industrial at 1.2 TW.h. The commercial and residential sectors consumed 0.7 TW.h and 0.2 TW.h, respectively. PEI’s electricity demand has grown 94% since 2005.
  • PEI’s renewable capacity increased from 15 MW in 2005 to 205 MW in 2018. Its share of generation from renewables also increased from 86% to 99% in this period. The Renewable Energy Act passed in 2005 contributed to this increase by requiring utilities to source a minimum of 15% of their energy from renewable sources (including out of province purchases) by 2010. In mid-2015, the Act was amended to eliminate this requirement.

GHG Emissions

  • PEI’s GHG emissions in 2017 were 1.8 megatonnes (MT) of carbon dioxide equivalent (CO2e) Footnote 1. PEI’s emissions have decreased 5% since 1990.
  • PEI’s emissions per capita are 12.1 tonnes CO2e per capita – 38% below the Canadian average of 19.6 tonnes per capita.
  • The largest emitting sectors in PEI are transportation at 47% of emissions, agriculture at 23%, and buildings (residential and service industry) at 20% (Figure 5).
  • PEI’s GHG emissions from the oil and gas sector in 2017 were zero.
  • In 2017, PEI’s power sector emitted 8.6 kilotonnes of CO2e emissions, a small fraction of Canadian emissions from power generation.

Data Sources

Provincial & Territorial Energy Profiles aligns with CER’s latest Canada’s Energy Future 2019 datasets. Energy Future uses a variety of data sources, generally starting with Statistics Canada data as the foundation, and making adjustments depending on individual province/territory circumstances.  Adjustments are necessary to ensure consistency and comparability across provinces/territories.
