PLANNING A SUSTAINABLE ELECTRICITY FUTURE

Modernizing Saskatchewan's Power Grid SUMA Convention Sunday, February 2, 2020

WHY WE’RE HERE TODAY

• Share our plans to power

SUSTAINABLE HOMETOWNS

• Listen to your concerns
• Answer your questions
• Identify areas for collaboration

WHY WE’RE HERE TODAY

Decisions about electricity affect everyone in Saskatchewan. It’s important to SaskPower that the future system reflects the input of people we serve. What do you want us to consider?

THE POWER SYSTEM TODAY

SASKATCHEWAN’S POWER MIX

GOAL TO REDUCE CO2 EMISSIONS BY 40% BY 2030

SASKATCHEWAN’S POWER GRID TODAY

Power plant generates electricity Transmission line carries electricity long distances Distribution line carries electricity to house Transformer steps up voltage for transmission Substation transformer steps down voltage Distribution transformer steps down voltage before entering homes

AGING INFRASTRUCTURE

• 25% of existing

infrastructure was put in place in the 1950s.

• Increasing rate of

failures is impacting service reliability.

• Costs to renew

infrastructure are rising.

MODERNIZE THE GRID

10

WHAT IS GRID MODERNIZATION?

Provides visibility, control and automation. Improves safety, reliability and efficiency. Enables future customer participation in the power system.

11

GRID OF THE FUTURE

12

DISTRIBUTION CONTROL CENTRE

• Monitors the health of the

system.

• Manages the flow of power

through the network.

• Remotely restore power

where possible (future).

13

OUTAGE MANAGEMENT SYSTEM

• Visibility of the network from

customer to substation.

• Enabled through ‘smart’ devices.
• Determines outage locations.
• Informs customers about outages

and restorations (future).

14

• Smart meters will report to the outage

management system.

• Meters detect:
• Power outages/restorations
• Energy consumption/demand
• Power quality.

MEETING YOUR CHANGING NEEDS

19

MEETING YOUR NEEDS

• Timely and accurate bills.
• Improved outage communication.
• Enables customer participation;
• distributed generation &

storage,

• demand response.
• Electrification;
• electric vehicles and heating.

20

SYSTEM PLANNING

• Must ALWAYS have enough

power available.

• Summer peak is catching up

to winter peak.

• Daily peaks flatter than

most utilities; we have more heavy industrial customers.

• Costs to build/maintain

infrastructure embedded in rates.

21

LOAD/SOLAR GENERATION

22

STORAGE POTENTIAL

• Surplus solar energy has

potential to be stored/ used during peak periods.

• Best applied at local

level, in summer.

• Does not change the
• verall system

requirements or costs.

23

MICROGRID

• Better economies of scale

than single customer solutions.

• Higher potential for reliable

supply (northern Sask).

• Many challenges still exist.
• Potential for community
• wnership models.
• Future considerations.

24

Basic Monthly, 23% Fuel, 23% Generation Facilities, 26% Transmission & Distribution, 28% Energy Charge, 77%

Breaking Down a Power Bill

Basic Monthly Fuel Generation Facilities Transmission & Distribution

BILLING CHALLENGE

• A decrease in customer

energy reduces the revenue used used to maintain infrastructure.

• SaskPower is looking at

restructuring rates to address this. There is no perfect formula.

• Rate structure changes take

time due to regulatory processes.

• Example For Discussion Purposes Only -
