<sup>496 Air Quality Regulations, made under sections 25 and 112 of the Environment Act S.N.S. 1994-95, c. 1 O.I.C. 005-87 (February 25, 2005, effective March 1, 2005), as amended, Schedule C. The mercury limitation allows NSPI to apply...
AI summary NSPI is subject to Air Quality Regulations and Greenhouse Gas Emissions Regulations, which impose mercury and GHG emission limits. The mercury limit allows an additional 10 kg of credits annually, effectively capping emissions at 45 kg/year. NSPI's compliance with these regulations is discussed, along with applicable limitations.

AI summary NSPI's fleetwide CO2 equivalent emissions under Nova Scotia's Greenhouse Gas Emissions Regulations are shown, with 27.5 mega tons from 2021-2024 and 6 mega tons for 2025. NSPI is also subject to the Output Based Pricing System (OBPS), which replaced Cap-and-Trade in 2023 and sets performance standards for individual generators.
Generating units that emit 50,000 tonnes or more of greenhouse gas emissions must participate in OBPS.498 Generating units that emit between 10,000 and 50,000 tonnes are eligible to apply to the Minister of Environment and Climate Change t...
AI summary Nova Scotia requires generating units emitting 50,000 tonnes or more of greenhouse gases to participate in the Output Based Pricing System (OBPS). Units emitting between 10,000 and 50,000 tonnes can voluntarily opt-in. Nova Scotia’s performance standards for solid fuels are less restrictive than federal standards but are expected to align by 2030. NSPI received approval to opt-in PHB and Burnside starting in 2023.
X.B.7.b. NSPI's Greenhouse Gas Emissions Results As explained above, NSPI is subject to two separate, independent regulatory frameworks governing GHG emissions. NSPI's compliance period for the province's Greenhouse Gas Emissions Regulatio...
AI summary NSPI is subject to two regulatory frameworks for GHG emissions. For 2021-2024, NSPI emitted 16.8 mega tonnes of CO2 equivalent, but remained in compliance as actual 2024 emissions were 5.6 mega tonnes. For 2025, emissions were 5.8 mega tonnes, under the 6 mega tonne cap. The OBPS program allows emissions with payment, and emission intensity limits vary by fuel type, with gas-fired units having the lowest and solid fuel-fired units the highest. Emission costs are expected to rise from $80/tonne in 2024 to $115/tonne by 2030.

AI summary The document presents data on OBPS allowed intensities and GHG costs from 2023 to 2030, along with NSPI's GHG emissions and compliance costs during the Audit Period. NSPI's compliance costs are reported as $42.3 million, but there is a discrepancy with the $40.9 million shown in Figure X-35. PHB generated the most OBPS credits, while Tufts Cove had the highest GHG compliance cost.

AI summary The document discusses NSPI's GHG emissions from 2021 to 2025, noting a 16% increase by 2025 compared to 2023, with the OBPS carbon-pricing mechanism being a contributing factor. Figure XI-11 illustrates the trend in emissions.
