PLANNING A SUSTAINABLE ELECTRICITY FUTURE Modernizing - PowerPoint PPT Presentation

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 2

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? 3

THE POWER SYSTEM TODAY

SASKATCHEWAN’S POWER MIX 5

GOAL TO REDUCE CO 2 EMISSIONS BY 40% BY 2030 6

SASKATCHEWAN’S POWER GRID TODAY Transmission line carries electricity long distances Power plant generates Distribution line carries electricity electricity to house Distribution transformer steps down voltage before entering homes Transformer steps up Substation transformer voltage for transmission steps down voltage 7

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. 8

MODERNIZE THE GRID

WHAT IS GRID MODERNIZATION? Provides visibility, control and automation. Improves safety, reliability and efficiency. Enables future customer participation in the power system. 10

GRID OF THE FUTURE 11

DISTRIBUTION CONTROL CENTRE • Monitors the health of the system. • Manages the flow of power through the network. • Remotely restore power where possible (future). 12

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). 13

OUTAGE MANAGEMENT & SMART METERS SaskPower • Smart meters will report to the outage management system. • Meters detect: Wireless Communication • Power outages/restorations Infrastructure • Energy consumption/demand • Power quality. SaskPower System 14

MEETING YOUR CHANGING NEEDS

MEETING YOUR NEEDS • Timely and accurate bills. • Improved outage communication. • Enables customer participation; o distributed generation & storage, o demand response. • Electrification; o electric vehicles and heating. 19

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. 20

21 LOAD/SOLAR GENERATION

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 overall system requirements or costs. 22

MICROGRID • Better economies of scale than single customer solutions. • Higher potential for reliable supply (northern Sask). • Many challenges still exist. • Potential for community ownership models. • Future considerations. 23

BILLING CHALLENGE Breaking Down a Power Bill - Example For Discussion Purposes Only - A decrease in customer • energy reduces the revenue used used to maintain Fuel, 23% infrastructure. Generation Energy SaskPower is looking at Basic Monthly, • Facilities, 26% Charge, 23% 77% restructuring rates to Transmission & address this. There is no Distribution, 28% perfect formula. Rate structure changes take • time due to regulatory Basic Monthly Fuel Generation Facilities Transmission & Distribution processes. 24

OUR MISSION Ensuring reliable, sustainable and cost-effective power for our customers and the communities we serve. Add cleaner Reduce Modernize the generation emissions grid options 25

OUR VISION Powering Saskatchewan to a cleaner energy future through innovation, performance and service. Add cleaner Reduce Modernize the generation emissions grid options 26

DISCUSSION QUESTIONS How do we plan a cleaner power future together? • What do you need from SaskPower? • What should we consider as we plan? • How do you want to engage with us? • Other questions? Please ask us! • 27
