June 2, 2009 RE: Guelph Area Transmission Infrastructure Refurbishment Class Environmental Assessment Dear: This letter is to inform you that Hydro One Networks Inc. (Hydro One) is initiating a Class Environmental Assessment (EA) to refurbish parts of the aging high-voltage electricity infrastructure serving the City of Guelph. Please accept this invitation to a public information centre (PIC) on June 10th to learn more about the project and meet with our staff. Parts of the high-voltage electricity system serving Guelph were installed starting in 1910 and require upgrades to keep pace with the economic growth and development in the area. This need and transmission solution were identified by the Ontario Power Authority, and confirmed by the local utility Guelph Hydro. Conservation and demand management and distributed generation will, however, continue to play a role in the electricity plan for the community. To ensure that Guelph Hydro customers continue to receive a safe and reliable supply of power Hydro One proposes two alternatives to refurbish the electricity infrastructure – both will involve upgrading the existing 115 kV transmission lines between Campbell Transformer Station (TS) and CGE Junction (see attached Notice). This will be coupled with either building a new transformer station within the study area or expanding our existing station at Cedar TS. No changes to the transmission line between CGE Junction and Cedar TS are required. The Class EA is being carried out in accordance with the process described in Hydro One’s Class EA for Minor Transmission Facilities. The project must also be approved by the Ontario Energy Board (OEB). Contingent on the outcome of the Class EA approval process, construction is expected to begin in late 2010 with the new facilities in-service by spring of 2012. The first PIC will be held on Wednesday, June 10, 2009 from 4 p.m. to 8 p.m. at the First Christian Reformed Church located at 278 Water Street, Guelph Ontario. Please refer to the attached map for information on the location of the study area and the PIC. The PIC will provide the community an opportunity to learn more about the project, provide input about project options, as well as discuss any issues or concerns with our project team. A second PIC will be held later this year to present the proposed transmission line upgrade, the TS site selection process and seek public input on Hydro One’s preferred TS site.

For our records, please complete and return the attached Fax Back Form indicating the appropriate contact person. We would be pleased to arrange a meeting to gather input/feedback and discuss with you the areas of interest and/or concern regarding this project. Hydro One has retained Dillon Consulting Limited to provide assistance in the Class EA study. Dillon may be in touch to gather relevant information for this project. If you have any questions regarding this project please contact me at (416) 345-6597 or Janice Martin, Environmental Specialist at (416) 345-5357 or by email at [email protected] Sincerely,

Guelph Area Transmission Infrastructure Refurbishment Class Environmental Assessment – Project Update

Dear Suzanne Young: In June 2009, Hydro One Networks Inc. (Hydro One) initiated a Class Environmental Assessment (EA) study to refurbish parts of the aging high-voltage electricity infrastructure in the City of Guelph. The transmission refurbishments coupled with Guelph’s conservation and demand management and distributed generation initiatives will help ensure the City’s continued economic growth and development. An initial public information centre (PIC) about this project was held on June 10, 2009 at the First Christian Reformed Church in Guelph. We are writing to inform you that Hydro One has introduced a new station alternative following public feedback received at the June session. This new alternative will be evaluated in the Class EA study. It also provides improved power supply reliability to Guelph and the surrounding area. Hydro One originally proposed two alternatives to refurbish the electricity infrastructure and ensure that customers continued to receive a safe and reliable supply of power. Hydro One’s third alternative involves installing a new switching station at the Guelph North Junction, which is north-west of Guelph in the Municipality of Centre Wellington (see attached Notice for location), upgrading the existing 115 kV transmission line between Campbell Transformer Station (TS) to CGE Junction, and replacing two of the existing transformers at Cedar TS. Please note that the transmission line upgrades proposed between Campbell TS and Cedar TS are similar for all three alternatives. The new alternative station site at Guelph North Junction is outside of the original study area for this project. As such, a public information centre is planned to advise the affected community and stakeholders about the project and provide them an opportunity to participate in the Class EA process and provide their input.

This second PIC will be held on Wednesday, November 25, 2009 from 4 p.m. to 8 p.m. at the Marden Community Centre, 7368 Wellington Road 30 (Marden Road), Township of Guelph/Eramosa. Please refer to the attached map for further information. In the new year, a third PIC will be held to present Hydro One’s preferred station site, the site selection process and the proposed transmission line upgrade, and seek public and stakeholder input. If you have any questions regarding this project or the new Alternative #3, please contact me at (416) 345-6597 or Janice Martin, Environmental Specialist at (416) 345-5357 or by email at [email protected]

Project Update: Guelph Area Transmission Infrastructure Refurbishment Project Dear, This letter is to update you on the Guelph Area Transmission Refurbishment Project. In June 2009 Hydro One launched a Class Environmental Assessment (EA) study to upgrade some of the area’s aging electricity infrastructure and to address new growth in the community. Parts of the high-voltage electricity system in Guelph were installed starting in 1910 and require upgrades to keep pace with the economic growth and development in the area. As well, conservation and demand management will continue to play a large role in the energy plans for the area. Hydro One originally developed two alternatives to meet the Guelph area’s needs and presented these at a Public Information Centre (PIC) on June 10, 2009 at the First Christian Reformed Church in Guelph. Alternative 1 • Build a new transformer station (TS) with two 230-115 kV transformers on a new site within the study area. • Replace approximately 5 km of an aging 115 kV transmission line between Campbell TS and CGE Junction with a two circuit 230 kV line. The line would operate initially at 115 kV. • Replace two existing transformers at Cedar TS that are nearing their end of life. Alternative 2 • Install two new 230-115 kV transformers at the existing Cedar TS site. • Replace approximately 5 km of aging 115 kV transmission line between Campbell TS and CGE Junction with a two circuit 230 kV line. The line would operate at 230 kV. • Replace two of the existing transformers at Cedar TS that are reaching their end of life. Based on studies today, Hydro One has developed a third alternative that would also meet the electricity needs for the region and presented all three options at a PIC at the Marden Community Centre in November 25, 2009.

Alternative 3 • Replace two of the existing transformers at Cedar TS that are reaching their end of life. • Replace approximately 5 km of aging 115 kV transmission line between Campbell TS and CGE Junction with a two-circuit 230 kV line. • Install a new switching station at the Guelph North Junction Since our last PIC, we have modified Alternatives 1 and 2 to also include the replacement of the two aging transformers at Cedar TS. As such, this component is now common to all three alternatives. These transformers are more than 50 years old and would be scheduled for replacement in the next few years as part of Hydro One’s regular asset maintenance program. It makes sense to co-ordinate this transformer replacement work with the other Guelph Area transmission refurbishments. Hydro One is continuing its analysis of the three alternatives and plans to present a preferred alternative to the community at a third PIC to be held in the fall of 2010. The project is expected to be in-service in spring 2014. Rest assured that we will continue to keep you informed as this project moves forward. Please do not hesitate to contact me at 416-345-6597, or Janice Martin at 416-345-5357. Information regarding this project is also available on our website at http://www.hydroone.com/projects/Pages/Default.aspx Sincerely,

May 22, 2012 , Re: Guelph Area Transmission Refurbishment (GATR) Project Recommencement of Class Environmental Assessment Dear , As a follow-up to our previous communication, in 2009 Hydro One Networks Inc. (Hydro One) began a Class Environmental Assessment (EA) process for a project that would refurbish parts of the aging high-voltage electricity infrastructure serving the City of Guelph and the surrounding area. Public Information Centres (PICs) were held in Guelph in June 2009 and Marden in November 2009 to introduce the project to interested parties and solicit input. In 2010 the Class EA process was put on hold while the Ontario Power Authority (OPA) commenced a broader regional planning study for the Kitchener-WaterlooCambridge-Guelph area. The regional planning study conducted in consultation with local utility partners has advanced sufficiently to confirm the need and urgency for the GATR project. This project will address the continued increase in electricity demand forecast for Guelph and the surrounding area. In a letter to Hydro One, dated March 8, 2012, the OPA recommends that Hydro One continue with development work for the GATR project including the completion of the environmental and regulatory approval processes. The OPA also recommends that the project include the following facilities to address the specific needs of South-Central Guelph and improve overall reliability of electricity supply for the region: • Install two new 230/115 kilovolt (kV) autotransformers at the existing Cedar Transformer Station (TS) in Guelph; • Upgrade approximately five kilometres of existing transmission line from 115 kV to 230 kV, between CGE Junction and Campbell TS in Guelph; and • Upgrade the existing Guelph North Junction in the Township of Centre Wellington to a switching station. The enclosed map outlines the project study area. The Class EA is being carried out in accordance with the process described in the Class EA for Minor Transmission Facilities. The transmission line upgrade portion of the project must also obtain Section 92 “Leave to Construct” approval from the Ontario Energy Board

2

(OEB). Contingent on obtaining Class EA and Section 92 approvals, construction is scheduled to begin in mid-2013, with completion expected by the end of 2015. Hydro One is planning to host final PICs in June 2012 to present the proposed project components, project schedule and provide opportunities for public and stakeholder input. PIC details are as follows: Thursday June 14, 2012 First Christian Reformed Church 5:30 pm to 8:30 pm 287 Water Street, Guelph

Tuesday June 19, 2012 Ponsonby Public School 5:30 pm to 8:30 pm 5923 Wellington Road 7, near Sideroad 14

Following the PICs, Hydro One will make a draft Environmental Study Report available for public review and comment, and will proceed to file its Section 92 application with the Ontario Energy Board. We welcome your comments and feedback on the Guelph Area Transmission Refurbishment project. If you are interested, we would be pleased to arrange a meeting to gather your input and discuss project details. Please complete and return the attached Project Participation Form, indicating the appropriate contact person. If you have any questions regarding this project please feel free to contact me at (416) 345-6597, or Janice Martin, Environment Specialist at (416) 345-5357 or by email at [email protected].
