“Atlantic Power Corp. has announced it is idling plants in North Bay, Kapuskasing and Nipigon but will be paid until the end of its contract on Dec. 31, 2017, while Northland Power’s Iroquois Falls facility says it will produce less power until April.
TransAlta Corp. has stated that its new contract provides a fixed monthly payment until Dec. 31, 2018, with “no delivery obligations.”…
The IESO will not provide information on how much the NUGs are paid, but told the Toronto Sun that the replacement NUG contracts will generate “ratepayer savings of up to $53 million over the next two years.”
Should numbers be disclosed, the value of the IESO’s employees in “conservation” roles could be established. The difference between the cost of not having supply from the four contracts redone/bought-out for 2017 and having that generation should benchmark the price of conservation to evaluate spending in that area.”
So now that we have a number of “up to” $53 million, I’ll use that to estimate the value of the IESO’s conservation spending.Read More »
Following a recent post in which I displayed the growth in hours the market failed to produce a positive price for electricity I was advised a much better indication of Ontario having too much committed supply is when the price exceeds the taxes on hydroelectric generators. I’ve since performed some research, and analysis, that do show this is a better methodology for estimating periods of surplus baseload generation (SBG).
The Ontario Ministry of Finance shows two charges levied on hydro-electric (hdyro) generators: property taxes and a water rental charge of 9.5% of “a stations’s gross revenue from annual generation”. The property tax escalates with the production level: 2.5% (of revenues) on the first 50 gigawatt-hours (GWh), 4.5% on the next 350 GWh, 6% on the next 300 GWh, and 26.5% on all annual generation above 700 GWh. This makes the top rate 36% (combining water rental and property tax).
OPG’s hydro generators have a number of rates, but all are between $40 per megawatt-hour (MWh), and $45/MWh. For simplicity, I picked $15/MWh (36% of $41.67/MWh) to query IESO data in order to estimate the percentage of hours Ontario has experienced surplus baseload generation.Read More »
Napanee gas plant: more flexible resources needed to offset intermittent wind — trouble is, they also push emissions up
January 23, 2017
The Canadian Wind Energy Association (CanWEA) summarized their submission on Ontario’s long-term energy plan (LTEP) to the IESO on their website. “Ontario is the Canadian leader in clean wind energy with 4,781 megawatts of installed capacity, supplying about 5 per cent of the electricity that Ontarians depend on,” CanWEA said. “Wind has been the largest source of new electricity generation across Canada over the past decade. Over this time, costs have come down as capacity factors have increased.”
Here’s the other side of that apparent success story. It’s not as rosy as CanWEA, the wind power industry lobbyist, would like you to believe.
The IESO just released the 2016 Electricity Data indicating industrial wind turbines (IWT) were responsible for the generation of 9.0 terawatts (TWh) of power, representing…
During the past decade’s green dumbing down of electricity communication the standard unit of output became the “home”. The unit is derived from dividing the annual output of a generator (usually one with unpredictably sporadic production) by the average annual consumption of a residential consumer. I updated my databases with the latest (2015) US EIA data, grabbed what the IESO admits to importing and exporting, and graphed out Ontario’s net exports to New York and Michigan in the trendy “homes” unit.
