There is currently 7,788 MW of existing installed hydroelectric capacity. However,
3
experience has shown that not all of this capacity will be available at the time of the
4
summer peak demand. To determine the capacity contribution of existing hydroelectric
5
stations at the hour of the summer peak, OPA completed the following assessment:
6
•
the total system hydroelectric production coincident with the hour of the summer peak
was determined for each year from 1996 to 2005. The hours when the summer peak
occurred are shown in Table 2 below along with the coincident hydroelectric capability;
and
•
the 10 year mean of the hydroelectric capability coincident with the system peak was
then determined to be 5,459 MW;
•
hydroelectric reserve was accounted for by adding 500 MW to the mean hydroelectric
capability coincident with system peak. Historically, there has been an average of
500 MW of hydroelectric reserve accepted by the IESO during the hour of the summer
peak in the operating reserve markets.

For capacity adequacy assessment purposes, based on the above analysis, the IPSP
18
assumes that 5,959 MW of existing hydroelectric capacity will be available at the time of the
19
summer peak.

CAPACITY VALUE OF NEW HYDROELECTRIC PROJECTS
2
The capacity value of new hydroelectric facilities is determined by applying either the river-
3
specific, or “fleet” ratio of the mean actual capacity contribution (at the summer peak) to the
4
total installed capacity as a “de-rating” factor to the installed capacity of new hydroelectric
5
facilities. The river-specific value is used for those new generators located on rivers with
6
existing hydroelectric facilities. The “fleet” value is used for those new generators located
7
on rivers with no existing hydroelectric facilities.
8
The de-rating factor for new hydroelectric projects on the Ottawa River, for example, is
9
determined by dividing the mean capacity contribution of all hydroelectric facilities on the
10
river at the summer peak by the total installed capacity on the river. The de-rating factor for
11
the Ottawa River is 80%.
12
For new facilities on undeveloped rivers or rivers for which hydroelectric production data is
13
not available, the fleet new hydroelectric de-rating factor is the ratio of mean capacity
14
contribution of all existing hydroelectric facilities at the summer peak in Ontario to the total
15
installed hydroelectric capacity. The fleet new hydroelectric de-rating factor is 73%.
16
Table 5 summarizes the new hydroelectric de-rating factors for specified river systems in
17
Ontario. The shaded cells represent those de-rating factors that are determined using
18
actual river specific data, whereas the unshaded cells indicate the fleet de-rating factor.
19
The de-rating factors were applied to 975 MW of “Active and Committed” new hydro units.
