CanWEA supports investigating mechanisms to make wind
dispatchable in the AESO EMMO.
A significant benefit of more wind offering into the Alberta
electricity market is an overall drop in energy price for
consumers and rate payers.
CanWEA is interested in understanding mechanisms which
would incent wind to sell services such as a downward
dispatch service, and how this would be broadly implemented
to maintain the FEOC principles enshrined in the regulations.
CanWEA is interested in better understanding what other
ancillary services AESO envisions wind can offer
Benefits such as Low Voltage Ride Through, frequency
response, VAR support, etc., and other benefits associated
with wind energy to help re-stabilize the electricity system
after a system fault is a key benefit that wind energy holds.
These benefits need to be brought forward and considered in
a broadly speaking manner.
CanWEA encourages the AESO to continue to seek
mechanisms to improve short term forecasts to ensure under
and/or over supply conditions are minimized.

CanWEA is encouraged to see the acknowledgement that
lack of wind will be considered an AOR for loss of supply.

7.2 System Ramping Service

AESO Comments Matrix
Given that wind is not the only cause of system ramping
events in the electricity system, this service should not be
solely borne by the wind industry itself rather, should be
socialized across the entire rate base, and paid for by the
market.
Inflexibility of baseload in Alberta contributes to reliability
issues during significant ramp events, whether these are
caused by wind alone, or in combination with
sudden/unexpected changes in demand/generation capacity
While CanWEA recognizes that significant ramp events can
result in reliability issues, as well as result in undesirable
price events, it is noted that these can be minimized through
additional mechanisms, and not just ramp rate limitations
through implementation of WPM – these include:
o Continued and increased investment in transmission,
both internal and inter-tie with neighbouring
jurisdictions with more flexible generation assets
o Continued improvement in short and mid-term wind
forecast
o Overall increase in flexibility of other system
components, both in demand side management and
generation technologies
CanWEA would like to better understand what the impacts to
ramp rate limitations would be on wind assets in Alberta, and
does not believe that this analysis has been sufficiently
completed by AESO in support of this recommendation. This
should include a broader analysis of the frequency of
occurrence, the amount (and manner) of generation assets
that would be curtailed, how AESO will impose curtailment,
what the economic impact is expected to be, and any
mechanisms to provide a financial incentive/instrument to
ensure economic dispatch of wind resources in Alberta.

7.3 Alter Regulating Reserve
Technical Requirements
-
CanWEA supports broadening the requirements to increase
the type of products and approaches that can be used in the
regulating reserve market, and considers it an overall benefit
to Albertans if other technologies, such as DSM and/or
storage can be incorporated into this service.

CanWEA agrees that as new technologies become available, including increased
use of variable sources of renewable power, faster and more flexible sources of
regulating reserve will be needed. This is in part driven by the increased
recognition that the lack of flexibility of many existing thermal sources of baseload
power may be limiting the modernization of the power grid, and reducing the ability
of system operators to procure more sustainable sources of variable renewable
power. This is therefore (and as appropriately noted by AESO), what is in part
driving the FERC review of regulating reserves.
CanWEA looks forward to continued consultation on the development of this
initiative by AESO.

CanWEA wishes to thank AESO for investigating mechanisms to improve the operational
and economic integration of wind energy in Alberta.
CanWEA looks forward to continued consultation on some the details of the
recommendations, as the recommendations become more refined, and additional
information is made public.
