Alberta, Electricity and Renewable Energy a simple version Warren Sarauer - Past Chair of SESA Board

Outline of Tonight’s Talk Part 1: Deregulated electricity system in Alberta Part 2: Understanding your bill Part 3: How renewable energy fits into this

Deregulated Electricity in Alberta

Cheapest form of energy? Efficiency = free to 25% of purchased electricity

Some of the players AIES Alberta Integrated Electricity System

AESO

Generation Types Baseload Generation designed to run all the time - 24/7 generally are thermal plants - coal, nuclear, hydro Intermediate Generation designed to step into the market to meet higher daytime loads NG cycle generators, wind, solar PV Peak Generation brief periods when load demand is highest ( afternoon - early evening ) NG turbines

AESO’s long term plan 2013 - installed “capacity” - no climate change policy input to report - renewables are 14.3% of US electrical generation in 2014 - solar PV doubled in 2014

Major Transmission Lines 5 AESO regions in Alberta Edmonton (Central) is the only net exporter of electricity 4,950 MW coal-fired generation vs 2140 MW consumption (winter peak 2011) 230% of your power comes from coal

The Generator In the Edmonton region more than twice of our consumed power is from coal-fired “base load” generation. 13 coal plants are located in the Wabamun area. Capital Power and TransAlta own them. Gas-fired plants are planned in that area as well as a coal mine expansion. ATCO has gas in Ft. Sask area. Some co-generation is being done locally as well. And more is coming on stream 220 micro-generators in Edmonton, 1000 in province

Solar produces different amounts of electricity around the world Alberta is one of the best spots in the world For a 1kW system Frankfurt = 850 kWh Edmonton = 1250 kWh 50% more

Power Pool

Wholesale Power Pool price is variable by the hour

Hourly Pool Price supply and demand affect price

the Grid is designed for the peak

AIES or just “the grid” “the grid” is a network of wires and poles and some other stuff that delivers the electricity from the generator to your home there is no storage available for these large amounts of electricity balancing this supply and demand is a highly complex task

The Wire-line Owner EPCOR (EDTI) owns and manages the local transmission and distribution “grid” This is a totally regulated portion of the “de-regulated” system. Planned by AESO and approved by AUC. Paid for by ratepayer (you)

Transmission Usage Ratios AESO’s long term plan 2013

Ratepayers “share” the costs

Near Future: Why is my bill so much higher than a few years ago? ! Delivery charges are about to DOUBLE over the next 5 years! ! ! !

Carbon tax on “heavy” emitters (100,000 tonnes annually) $15 a tonne of carbon taxed on the top 12% of emission graph is courtesy of Pembina Institute report

Your electricity bill How does this show up on my bill?
