Thank you very much for inviting me to be here today.
As the head of the largest energy and environment public affairs practice in Canada, I am proud to lead a team that has had a lengthy history of representing and advising energy stakeholders on the intricacies of electricity system planning, policy, regulation, and procurement. Having entered the consulting area during the period of electricity market opening and deregulation across North America in the late 1990s, I have seen a myriad of policies and imperatives that affect the shape and scope of electricity markets, particularly in my home province of Ontario.
From the initial thrust to encourage private sector investment in a system that had become overwhelmed by aging assets and questionable reliability, to the transition of coal-fired generation to natural gas and renewables starting in the 2000s, to the emergence of expanded conservation and demand management, embedded generation at the distribution level, new technologies, products, and services have been emerging at an incredible pace, challenging conventional notions of how we supply and we use electricity.
Many of the witnesses who have appeared before this committee on various facets have spoken on regional differences in our electricity markets. They've also noted the importance of carbon policies and how moving to cleaner and lower-emitting forms of power is of increasing importance on both sides of the border.
Notwithstanding the recent proposed repeal of the clean power plan by the Environmental Protection Agency in the United States, I believe that economic rationalism, securing the lowest marginal resources to maintain electricity reliability across markets and jurisdictions, and doing so through low and non-emitting resources, is completely possible, if not probable.
The topic for today is the strategic role that interties can play in that process. No doubt can be given on the various attributes of an integrated Canadian electricity market from east to west or, perhaps more appropriately, from Ontario east and from Manitoba west. Some have noted the importance of seeking new markets in the United States, and the historical and continued importance of resources in Quebec and Atlantic Canada serving the eastern seaboard.
I will focus my comments on the future of the Ontario electricity market and how system planning and policy value related to interties will increase in the future.
Two dynamics are arising that will support additional intertie usage and development in the future. First, there is a need for greater flexibility to maintain reliability while securing new capacity and regulation services that support added variable and embedded generation in the province. Second, there is a value in utilizing interties to help secure new, low-cost energy supply when needs arise in the coming decade.
As reinforced in the Ontario Independent Electricity System Operator's, May 2017, Ontario-Quebec interconnection capability technical review, on an hourly basis, Ontario's wholesale electricity market economically schedules energy transactions to and from Ontario via the interties, providing an important balancing function that helps address the peaks and valleys of electricity demand, and ultimately, lowers costs to consumers.
Electricity trade provides valuable operational flexibility that helps the IESO manage increased variability as more wind and solar resources are integrated into the system, as more generation is connected at the distribution level affecting demand for grid-supplied energy, and as consumption patterns become less predictable.
Ontario continues to witness significant growth in these types of resources. Reliability in the Ontario market today is strong due to a continued build-out of conventional, utility-scale, and distribution-enabled resources across the province. Regulatory and policy areas have adjusted to support the growth of these resources over time. However, as we add these types of resources into the Ontario supply mix, and as residential and consumer businesses are looking to self-generation through mechanisms such as net metering and cleaner forms of supply, enhanced resilience in the market will be required to support future needs.
Intertie transactions can be beneficial, as they can measurably improve the reliable, cost-effective operation of Ontario's power system. According to the IESO, interconnected electricity markets provide a significant opportunity to officially utilize the energy generated from a diverse range of resources over a much greater geographic area, thereby lowering the cost of producing and managing electricity for all parties. Interties with neighbouring jurisdictions expand the options available to meet system needs, and Ontario's interties have, according to the IESO, provided both reliability and economic benefits to the province for over a century.
The need for new resources in Ontario for the coming years is clear, and we expect that this will be outlined in the anticipated release of the long-term energy plan. As we can see from the IESO's 2016 Ontario planning outlook, under all scenarios the need for new supply resources will arise in the early 2020s, particularly to maintain reliability following the decommissioning of the Pickering nuclear generating station.
Interties can provide a beneficial option to system planners in securing new resources. This was underscored in the recent approval by the National Energy Board of the Lake Erie connector, a merchant HVDC intertie proposed to connect Ontario to the PJM market via an underwater cable.
As was stated by the NEB, “the NEB...determined that the project would provide benefits to Indigenous, local, regional, and provincial economies, allow greater flexibility for two large energy markets to meet changing energy needs, and increase market efficiency for Ontario and its rate payers.”
To conclude, as more and more jurisdictions set carbon policies and emission regulations that dictate the supply mix and emission profiles of the electricity sector, understanding and tracking the attributes of electricity generation is a developing and evolving need for electricity system operators and policy-makers.
Numerous jurisdictions have implemented some form of tracking system that collects and tracks generation attribute data. The key elements provided by these tracking systems vary across jurisdictions but generally include tracking emissions attributes for every megawatt hour generated, calculating average and residual emission rates, tagging emissions attributes from power source to sink, tracking interjurisdictional power transactions and inter-registry imports and exports, supporting carbon allowance adjustments for voluntary markets, and making public reports to provide transparency.
Ultimately the goal of these tracking systems is to avoid the double-counting of attributes or emissions savings tagged to specific imports and exports. Today, robust registry and tracking systems exist in PJM, NE Power Pool, and the New York ISO, while Michigan has a renewable energy certification system in place. We believe that Ontario will also develop such a protocol as a matter of course.
I hope this provides some additional usefulness to the committee in its deliberations, and I look forward to your questions.
Thank you.
