Central Toronto Integrated Regional Resource Plan (IRRP)

Introduction to the Engagement and IRRP Overview

2

THIS WEBINAR IS THE BEGINNING OF AN ENGAGEMENT PROCESS

• Introduction to the Integrated Regional Resource Plan

for Central Toronto

• Information on opportunities to provide feedback
• Answer questions about this plan
• A contextual workbook with more information is online

THE REGIONAL ELECTRICITY PLANNING PROCESS IN ONTARIO

• An Integrated Regional Resource Plan (IRRP) looks at

the long term trends for electricity requirements and the different ways to meet the need for:

– Capacity to supply demand – Reliability for meeting standards and customer expectations – Supply security for the urban centre

• The IRRP is jointly developed by a Working Group

– Ontario Power Authority – Toronto Hydro-Electric System Limited – Independent Electricity System Operator – Hydro One Networks Inc.

TORONTO IS ONE OF 21 REGIONAL PLANNING AREAS ACROSS ONTARIO

Regional Planning Zones

• 1. Burlington to Nanticoke
• 11. London Area
• 2. Greater Ottawa
• 12. Peterborough to Kingston
• 3. GTA North
• 13. South Georgian Bay/Muskoka
• 4. GTA West
• 14. Sudbury/Algoma
• 5. KWCG
• 15. Chatham/Lambton/Sarnia
• 6. Metro Toronto
• 16. Greater Bruce/Huron
• 7. Northwest Ontario
• 17. Niagara
• 8. Windsor Essex
• 18. North of Moosonee
• 9. East Lake Superior
• 19. North/East of Sudbury
• 10. GTA East
• 20. Renfrew
• 21. St. Lawrence

THIS PLANNING PROCESS EXISTS TO SERVE YOUR NEEDS

• We want to know:

– Your expectations around electricity service – The value you place on higher levels of service – Your preferences around options to meet Toronto’s electricity needs

• Your input will help shape the electricity plan
• Perspectives may vary based on the type of customer:

− Residential, multi-residential, commercial, institutional, etc.

Peak Demand (MW)

Year

Actual historic peak demand

Factors that can drive demand upward:

• More economic growth
• More people moving into the city
• Electrification of transportation
• Less than expected Conservation results

Factors that can bring demand down:

• Shifting to less energy intensive commerce
• Reduced pace of growth
• Increasing end-use efficiency
• More stringent building codes

COST

TIMING

ENVIRON- MENTAL IMPACTS

• Each option has strengths and weaknesses
• An integrated plan includes a mix of options

that is affordable and acceptable to the community and approval authorities

OTHERS ??

CONSERVATION AND DEMAND MANAGEMENT (CDM) OPTIONS

• Conservation is an important consideration in regional

planning

– Opportunity to deploy provincial CDM resources in areas where local electricity needs have been identified – Next generation CDM plans and programs can contribute to regional and community energy planning goals

• CDM opportunities for consideration:

– Targeted marketing in specific areas with needs – Focusing on programs with greater energy savings at peak – Local demand response and district energy systems – Updating local building codes and standards

• Cost and lead time vary based on type of CDM, some

programs could be implemented in 1-2 years

16

DISTRIBUTED GENERATION (DG) OPTIONS

• DG can contribute to the reliability and security of supply

in local areas

– Scalable resources can be built up over time

• Different types of DG for consideration:

– Renewable resources such as solar, wind, biogas/biomass – Combined heat and power systems – Emergency and backup generation

• Cost and lead time (2-5 years average) vary based on

type of resource

17

TRANSMISSION AND DISTRIBUTION OPTIONS

• Wires options can have economies of scale, and

significantly contribute to reliability and security

• Space for new transmission and distribution is

constrained in built up urban areas

• Depending on the type of capacity need, options can be:

– New load station (s) – Transmission lines and stations

• Cost and lead time (5-7 years average) vary based on

the type of facility
