The AP1000 is Westinghouse’s innovative Pressurized Water Reactor model Based on nearly 70 years of research and development, the AP1000 reactor builds and improves upon previously established technology used in Westinghouse-designed plants since the 1950s.The AP1000 technology offers three distinct advantages when compared to previous generations of nuclear reactors: 1 Economic competitiveness • The AP1000 reactor operates a global fleet and has achieved Nth-of-a-kind status. • The technology has a strong licensing pedigree in the U.S., U.K., Europe, and China. • The technology’s primary goal is simplification, with fewer components and reduced building volume required, thereby saving capital and operational costs. • Its modular design accelerates construction and reduces risks by enabling more factory-based work, which offers superior quality and cost control, with lower labour in on-site construction and development. 2 Enhanced Safety • The AP1000 employs passive safety systems, which can operate even in the absence of operator actions or external power. • The reactor is designed to exceed the U.S. Nuclear Regulatory Commission's safety and risk criteria by a significant margin. • Simplified safety systems reduce surveillance needs and reduce the likelihood of forced shutdowns. 3 More efficient Operations and Maintenance • Superior operating performance – availability and capacity factors are in excess of 92%. • Dramatically reduced start-up test programs from ten months to five months or less. • Industry performance records set for first cycle refuelling outages (28 days) second cycle (19 days). *Safety grade. Compared with previous generation of nuclear power plants producing the same energy output • Plants used for both baseload and load-follow modes with ramp rates of one MW/second. • Lower operating and maintenance requirements lead to smaller maintenance staff needs, saving costs. Compared to generating electricity from the combustion of fossil fuels, a single AP1000 reactor unit is capable of reducing CO emissions by seven 2 million metric tons annually. The four unit AP1000 Project would result in a reduction of 28 million metric tons of CO emissions, comparable to the 2 environmental impact of removing seven million passenger vehicles from the road.

3 Economic Footprint of Westinghouse Activity

Our approach assesses the direct, indirect and induced economic footprint of manufacturing, engineering and installation and ongoing operations of the proposed AP1000 Project The economic footprint of Westinghouse’s AP1000 Project is assessed in two stages: 1. Manufacturing, engineering and installation 2. Ongoing AP1000 Project operations Over 1,600 direct jobs sustained over the period Expected to provide tens of billions of dollars of investment in Canada Carbon-free energy provided for over three million homes 1 2 Manufacturing, engineering and installation period expected to span 16 years Operational lifespan of the plant: minimum of 60 years The planned spending on the AP1000 Project would generate economic impact through the following channels: • Direct impacts result from companies’ spending on suppliers and employees. • Indirect impacts arise from the activities of the firms providing inputs to a company’s suppliers (in other words, the suppliers of its suppliers). • Induced impacts are the result of consumer spending by employees of the businesses stimulated by direct and indirect expenditures. • The total economic impact is equal to the sum of the direct, indirect, and induced economic impacts. These calculations were developed through PwC’s economic modelling. These values represent gross calculations of the economic footprint of the AP1000 Project.

4 Broader Impacts of Westinghouse Activity

Westinghouse’s AP1000 Project will have broader impacts in Ontario and across Canada The impacts of the AP1000 technology deployment go beyond the economic footprint presented earlier in this report. The following slides highlight how deployment of this program could contribute to a broader range of impacts including: 1. Skill development: the nuclear industry and its supply chain create high-skilled, well-paid jobs in Canada. A critical part of Westinghouse’s planned investment is in enabling Canadian training and human capital to make sure Canada has skilled employees who can safely and efficiently operate the reactor. 2. Nuclear cluster development: there is already an extensive pan-Canadian nuclear supply chain including uranium mining and refining in the Prairies, manufacturing of specialised equipment, research, power generation and waste management across a number of provinces. As the first grid-scale nuclear build in Canada for 40 years, the Westinghouse AP1000 Project would boost Canada’s nuclear cluster and allow Canadian suppliers to benefit from the large number of AP1000 units that are expected to be deployed around the world. 3. Climate, safety and community engagement: nuclear investments can make a major contribution to the communities where they are located and to Canada’s net-zero commitments by providing additional capacity of carbon-free electricity. Westinghouse also brings a strong track record of safety and adheres to high technical and regulatory standards.

Nuclear energy can help to meet net-zero targets • Nuclear energy is likely to play an important role in the global road to net-zero. For example, the International Energy Agency estimates that nuclear power capacity will need to double between 2020 and 2050 to achieve global net-zero GHG emissions by 2050. • Nuclear electricity in Canada displaces about 50 million tonnes of GHG emissions annually, equivalent to removing 10.7 million passenger vehicles off the road. • Electricity from exported Canadian uranium helps to offset more than 300 million tonnes of GHG emissions worldwide. • In 2022, Westinghouse committed to achieving net-zero GHG emissions by 2050, in alignment with the Paris Agreement. • Westinghouse is committed to enhancing its environmental stewardship through a multifaceted approach. This includes the implementation of comprehensive energy reduction strategies, the improvement of waste management practices, the advancement of water conservation policies, and the establishment of measures to protect ecosystems. • Westinghouse has reduced its Scope 1 emissions by 20% and Scope 2 emissions by 31% from its baseline year of 2019.

Appendix B: Input-output methodology Input-output modelling: overview The fundamental philosophy behind economic impact analysis is that spending on goods and services has attendant impacts throughout the economy. For instance, construction expenditures will generate demand for the inputs to this process (such as tools and labour) that in turn generates additional demand that extends beyond the initial spending. This analysis permits the estimation of this cascading effect by using an input-output model of the Canadian economy. Inputs used for the economic footprint assessment are provided by the Westinghouse Electric Company’s estimates of capital expenditures, operating expenditures and revenues associated with the manufacturing, engineering and installation and operations of the AP1000 Project in Ontario. The input-output model used for the purpose of this report estimates the relationship between economic activity for a given good or service and the resulting impacts throughout the economy (including demand for other goods and services and tax revenues). For the purpose of this report, economic impacts were estimated for the following measures of economic activity: • GDP – the value added to the economy, or the output valued at basic prices less intermediate consumption valued at purchasers’ prices. • Employment – the number of FTE jobs created or supported. • Labour income – the amount earned by the employment expected to be generated. • Government revenue – the amount of revenue collected by the provincial, local and federal government. It includes personal and corporate income taxes collected on a provincial and territorial level, as well as other direct and indirect taxes. The economic footprint was estimated at the direct, indirect and induced levels: • Direct impacts are those that result directly from the company’s expenditures on labour and capital as well as gross operating profits. • Indirect impacts arise from the activities of the firms providing inputs to the company’s suppliers (in other words, the suppliers of its suppliers). • Induced impacts are the result of consumer spending by employees of the businesses stimulated by direct and indirect expenditures. 29
