From Parker Gallant’s Energy Perspectives, a view of how much wind power is costing Ontario.
Almost a week after Premier Wynne announced her plan to reduce our electricity bills by 25%, the wind was blowing! On March 8th, six days after the cost shifting announcement (from ratepayer to taxpayer), potential power generation from wind was forecast by IESO to produce at levels of 80/95% of their capacity, for many hours of the day. IESO was concerned about grid stability and as a consequence, curtailed much of the forecasted generation.
When the Premier made her announcement about reducing hydro bills, she also claimed “Decades of under-investment in the electricity system by governments of all stripes resulted in the need to invest more than $50 billion in generation, transmission and distribution assets to ensure the system is clean and reliable.”
It is worth noting that much of that $50 billion was spent acquiring wind and solar generation and its associated spending on transmission, plus gas plants (to back them because the power is intermittent), and distribution assets to hook them into the grid or embed them with the local distribution companies. It would have been informative if Premier Wynne had had Energy Minister Glen Thibeault provide an accounting of exactly what the $50 billion was spent on.
As it turned out the amount of curtailed wind generated on March 8th was 37,044 megawatt hours (MWh) was just short of the record of 38,018 MWh set almost a year ago on March 16, 2016 (estimated by my friend Scott Luft). The curtailed wind on March 8, 2017 cost Ontario’s ratepayers $120/MWh or $4,445,280.
The cost on March 16, 2016 was $4,562,160.
What does it mean? Curtailing or restricting power output but paying for it anyway means a portion of the $50 billion spent was simply wasted money. It went to the corporate power developers that rushed to sign those above-market contracts for renewable power.
Millions here, millions there= a whole lot of wasted money
The other interesting aspect of the surplus power generation on March 16th, 2016 and March 8th, 2017 is revealed in IESO’s Daily Market Summaries: the hourly Ontario energy price (HOEP) March 16th, 2016 was negative at -$1.25/MWh and on March 8th, 2017 was also negative at -.49 cents/MWh. This meant ratepayers paid for surplus exports sold to our neighbours in New York and Michigan, etc. Net exports (exports minus imports) on March 16, 2016 were 52,368 MWh, and on March 8, 2017 were 37,944 MWh. Total costs of their generation (HOEP + GA) fell to Ontario’s ratepayers along with the cost of any spilled hydro, steamed off nuclear and idling gas plants.
So, bear with me here, if we price the cost of the net exports at $110/MWh for those two days, ratepayer costs were approximately $9.8 million with $5.7 million for March 16, 2016 net exports and $4.1 million for March 8, 2017 net exports, not including the $84,000 we paid our neighbours to take our power.
How much did it cost you? Two days out of 729 (2016 was a leap year) cost Ontario ratepayers about $18.1 million for power not delivered (curtailed wind) or needed (net exports).
I hope this helps Minister Thibeault in his calculations for a long overdue accounting of where the other $49.982 billion went.
