Abstract
Canada is committed to eliminating greenhouse gas emissions from its electricity system. The Clean Electricity Standard (CES) policy intends to enforce a net-zero electricity system by 2035 in which all thermal generators must be ceased. While many parts of Canada are already there, many are not. And the need to grow electricity supply to meet new electrical demand will add to the pressure. The purpose of this paper is to present for the first time in Canada a Python-based generator-level model that will be used to illustrate how 2035 electricity decarbonization will affect thermal capacity, generation, and carbon dioxide emissions. In this thesis, we review electricity markets across Canada and the clean electricity policies in each province. We explore what the 2035 CES policy will mean for the electricity sector in terms of how the policy will truncate the installed capacity and energy produced from thermal generators, and the amount of CO2 released. We discuss what we call the spatial impacts of clean energy policies in terms of where the impacts will most be felt on a regional level in terms of jobs affected. Finally, we discuss opportunities to reduce the adverse community effects of this policy. For our main results, we find that relative to letting thermal power plants live out their current expected lives, the CES policy will truncate 22 percent of fossil capacity-years, reduce 17 percent of CO2 emissions (68 megatonnes from 2035 onwards) and put at risk 21.7 percent of jobs at thermal power plants. Knowing when and where a facility closure will take place can allow targeted deployment of training resources for those in need, long-term budgeting that includes tax revenue losses, and advance planning for transitioning individuals to local jobs in environmental remediation of fossil facilities and new clean electricity generation. The ability of coal mines and other fuel supply to operate at efficient scales in order to stockpile fuel while serving out existing contracts will also be facilitated by clear expectations as to when and where generator retirements will occur.
