I started receiving messages last night on a sorta report by Environmental Defence (ED), and as I am still receiving them, I thought I’d write some thoughts – if only to simply copy a link when again asked for my thoughts.
Here is how ED’s Keith Brooks begins a blog post on their latest “work”:
Electricity prices in Ontario have risen in recent years, putting the squeeze on some Ontario residents and businesses. There are many reasons for the increase in electricity prices and renewable energy is one of them. However, the role of renewables in diving up electricity bills has been vastly exaggerated.
I wrote on a poor 2014 ED work and noted their new backgrounder contains a graphic with the same information as Figure 1 of their 2014 work. Without acknowledging any level of competency in the compilation of data for either ED graphic, here’s the elements of residential electricity bills as they report them for 2016 and 2014:
Perhaps the “role of renewables in driving up electricity bills” is perceived as being significant because:
Yesterday Ontario’s system operator released a number of reports. Personally these reports provide opportunities to check the performance of the system compared to my expectations, and estimates, and they also provide an indication of how well the IESO adjusted to taking over the responsibilities of the former Ontario Power Authority (OPA) after 2014.
The data released includes:
Updated Ontario Energy Report website with 2016 1st quarter information, with related electricity report (.pdf), and data file (.xlsx)
2016 Q1 Progress Report on Contracted Electricity Supply (.pdf)
18 month outlook (.pdf) and related date file (.xlsx)
On first flip through the reports, the graphic that most caught my eye was the 18-month outlook’s “Table 4.1 Existing Generation Capacity as of…” This table shows not only what the IESO considers the capacity, by fuel type, participating in their market, but also what I will call “Capacity Value” and they call “Forecast Capability at Outlook Peak.” This is an important number because it’s used to measure the system’s ability to meet anticipated peak demand. The numbers that caught my attention were a 280 megawatt (MW) capacity of solar, with the forecast capability at peak of 28 MW. The 10% capacity value that indicates is sharply reduced from the 18 month forecast of June 2015.
Let’s ignore the low installed value for solar for a fleeting moment, and concentrate on the reduced capacity value. This June’s 18 month report explains it:Read More »
