IESO - Who We Are and What We Do

The Independent Electricity System Operator (IESO) works at the heart of Ontario's power system – ensuring there is enough power to meet the province's energy needs in real time while also planning and securing energy and its delivery for the future. It does this by:

• Planning

• Ensuring supply

• Operating the grid

• Engaging communities

• Promoting conservation

The IESO and the former Ontario Power Authority (OPA) merged on January 1, 2015 under the name Independent Electricity System Operator

ELECTRICITY PLANNING IN NORTHWEST ONTARIO

The Three Levels of Electricity Planning

7

Background – Bulk System Planning

• A process for identifying and meeting local electricity needs; objective of maintaining a safe and reliable electricity supply

• It is the link between provincial bulk system planning (led by the IESO) and local distribution system planning (led by LDCs)

• Operates in the context of existing criteria and frameworks

– Applies the IESO’s reliability standards

– Aligns with planning policies

– Accounts for local interests

• Integrated approach: looks at conservation, generation, wires and other innovative solutions

• A Working Group has been established to develop regional plans – for Greenstone-Marathon this includes the IESO and Hydro One Networks Inc.

What is Regional Planning?

8

• Engagement meetings in Thunder

Bay in fall 2014 to kick-off scoping

process for:

– Thunder Bay

– West of Thunder Bay

– Greenstone-Marathon

• Following a public comment period,

the final Scoping Report was

posted in January 2015 and the

IRRP process begun for the three

planning areas

GREENSTONE-MARATHON INTERIM IRRP (PRESENT-5 YEARS)

11

• An IRRP is being developed to provide recommendations to municipalities, First Nation communities, Métis community councils, and industry stakeholders related to what the most economic and technically feasible electricity solutions are for the region

• An Interim IRRP report has been developed with community input to facilitate decision making related to electricity supply for near-term industrial and community developments in the area

• The medium and long term plan will also be developed with community input and informed by this LAC

Introduction to the Greenstone-Marathon IRRP

13

Local Electricity System

• Mining development

• Gas to oil pipeline conversion project

• Recovery of forestry industry

• Growth in communities

14

Drivers

• Greenstone sub-system: – Industrial customers drive the need for additional capacity

requirements in the near term

• North Shore sub-system: – Existing system expected to be adequate to supply all forecasted

demand scenarios (see Appendix A)

• Marathon Area sub-system: – Existing system expected to be adequate to supply all forecasted

demand scenarios (see Appendix B)

– Confirmed by System Impact Assessment for Marathon PGM-Cu project

15

Near-term (present-5 years) Needs

Scenario A

• LDC demand growth (including two sawmill re-starts) from existing stations

• No large industrial projects materialize

Scenario B


• Geraldton area mining project:

• phase 1 mine (2018)


Scenario C


• Geraldton area mining project:



• Pipeline conversion project:

• 4 oil pumping stations (2020)

16

Near-term (present-5 years) Needs: Greenstone Subsystem Forecast Scenarios

The Greenstone-Marathon IRRP working group does not consider these

forecast scenarios to be of greater or lesser likelihood.

Notes:

1. Scenario A does not require the development of alternatives because the existing system is

capable of supplying growth while meeting all planning criteria

2. Maps of alternatives are included in Appendix C

Scenario C – Alternatives Analysis


($ millions)

Option C1 1) Install power equipment to support service quality needs at customer mining site (reactive compensation device providing +40 MVar)

2) New 230 kV Line to Longlac 3) Off-grid gas generation for two pumping stations

170

Option C2 1) Install power equipment to support service quality needs at customer mining site (reactive compensation device providing +40 MVar)

2) New 230 kV Line to Longlac 3) New 115 kV line Manitouwadge-Longlac

Notes:

1. Maps of alternatives are included in Appendix C

Alternative Analysis: Observations

• All economic alternatives have a common first stage: – Install reactive compensation (+40 MVar synchronous condenser or STATCOM)

at the Geraldton mine site to accommodate phase 1 of the mine.

• Grid-connected alternatives are more cost-effective than off-grid alternatives

• Large grid-connected generation is more costly than transmission reinforcement

• A new 230 kV transmission supply is the most cost-effective way to supply the Geraldton mine and the pipeline conversion project for 2020 (Scenario C)

21

Scenario Recommendation

Stage 1 (for 2018) Stage 2 (for 2020)

Scenario A No new facilities required

Scenario B

Recommended Near-term Plan: Stage 2b

Scenario B

• Geraldton mine phase 2 proceeds, but pipeline conversion project does not proceed by public 2020 date

Recommendation

• Install new customer generation in the form of two 10 MW natural gas gensets at the Geraldton mine site, or replace line sections of A4L

In-service date

• 2020


• $35 M – Line Section Replacement

• $50 M – Customer Generation

New gas DG

Replacement 115 kV line

OR

Implementation Considerations

• The plan elements are driven by industrial customer development and therefore, in accordance with the Ontario Energy Board’s Transmission System Code, benefitting customers are responsible for the related costs

• Lead-times can be accommodated, but new transmission would require urgent action by the benefiting customers for 2020 in-service, based on typical lead times

• The IESO is available to provide support for any regulatory and / or environmental approvals

• The IESO does not have a mandate to procure facilities for individual customers
