Canada’s first local electricity market is off to a promising start. Breaking new ground, a wide variety of local distributed energy resources (DER) will start delivering services to the grid on May 1. During the November 2020 capacity auction, a range of projects totalling 10 MW were accepted at a clearing price of $0.64 per kW-day. Although it was only a demonstration project, the results appear to be attractive, indicating that local utilities and transmission system operators may benefit from distributed market-based local capacity and the ability to defer more expensive infrastructure upgrades. Major innovation could be afoot if this kind of market continues to develop and grow.

The following is a summary of an expert panel discussion on the York Region Non-Wires Alternatives Demonstration Project. The panel was held online as part of the APPrO 2020 conference on December 2, 2020, soon after the first capacity auction results were announced.
Panelists:
Pat Lo, Senior Manager, Partnerships, IESO
Geri Yin, Head, Grid Innovation, GRE&T Centre, Alectra Utilities
Jen Hiscock, Assistant Program Director / Smart Grid & Energy Storage, Natural Resources Canada, and Session Moderator
Jen Hiscock: This new demonstration project, valued at more than $11 million, marks the first time NRCan (Natural Resources Canada) has invested in this kind of market-based solution. Rather than focusing on technology application, the project looks at how development of a local market might make services available economically to the wholesale grid. Funding has been provided equally by the federal government and the IESO.
The project area covers a subset of the Alectra service territory. It was chosen based on the location of expected demands on the distribution and transmission grids, looking at what could be done on the distribution side to address some of the system constraints if a non-wires alternative approach is taken. Existing stations are approaching their limits, and a growth trend is anticipated for a number of years. The question arose as to whether some of the needed capacity upgrades could be deferred by leveraging existing or new customer-owned assets.
The assets under consideration ranged from 100 kW to 3 MW – like batteries and space conditioners, remotely controllable. Resource types include demand response, gas-fired generation and storage.
The first market auction, which sought 10 MW of capacity for a 6-month commitment period from May to October 2021, had just cleared at the time of the conference, at a price of $0.64 / kW-day (see chart). Another auction is scheduled for fall of 2021.
Pat Lo: One of the objectives of the project was to find out what resources are available in the community, and to identify specifically what local resources could be used to meet local system needs. What value streams are available among these non-wires alternatives? And under the heading of interoperability, what value would there be at the wholesale level as well? What correlation might there be between prices in the transmission and distribution markets? How reliable will the resources be? Are the various types of resources available competitive with each other?
Geri Yin: The capacity auction was run on November 18 and 19, 2020 – a real competition! Local resources representing 34.3 MW of capacity registered to participate, well exceeding our set capacity target of 10 MW. We’ve seen a diverse group of participants: aggregated residential customers, supermarket operators, manufacturers, a district energy utility, and other local companies are among the successful providers. The types of DERs that have cleared the capacity market include behind-the-meter CHP, C&I Load Curtailment, Residential DR (Smart Thermostats), and behind-the-meter Gas-fired Generation.
The local capacity market cleared at a competitive price of just $0.64/ kilowatt-day, or $640/MW-day. This was 40% of the price cap which was $1.6/kw-day or $1,600/MW-day. The demonstration’s clearing price for the full six-month commitment period (May – October) in 2021 is about $80,000/MW.
The capacities cleared through the local auction market were pretty much evenly distributed among the two zones – zone 1 in Vaughan and zone 2 in Markham and Richmond Hill. The two-zone market is expected to generate more learnings and enable better understanding of local market dynamics that can be used during the next round of the market auction.
Alectra was thrilled with the results of the auction. The amount of interest from the market and the diversity of the successful participants and resources shows tremendous potential for using local solutions as a cost-effective alternative to traditional electricity infrastructure to meet local and regional energy needs. It is clear that there is a viable local market for DERs to participate as grid energy resources.
Another important aspect is that this local market gives the community the opportunity to take an active role in building a more sustainable grid - by deferring traditional infrastructure, while at the same time generating a new source of income.
Jen Hiscock: Remember that nobody put a thumb on the scale in any way to determine who would win or who would perform better in this auction. We tried to make the playing field as level as possible. It’s also good to see the level of resources that can participate – resources in the range of a few hundred kilowatts would never be engaged at the scale the IESO deals with. In addition, the new sources of revenue created for customers will help them commit to increasing electrification. This could be important considering that efficiency alone may not be enough to get to the 2050 decarbonization goal.
Questions
1. The pilot has allowed testing of a number of parameters, but there are others we can’t yet test. What limitations in testability did it encounter?
Pat Lo: The dispatch process will be real, not simulated. The IESO will be calling on the resources, and they will come online. However, we can’t directly apply the results to the wholesale market. Some of the remaining barriers are in the regulatory domain. But the regulator is highly involved and is reviewing the project. We’re hoping that, working with the regulator, we’ll be able to provide enough insight so as to make broader choices in the future.
2. There’s always been some doubt as to how many customer assets we can leverage. Tell us about the process of recruiting customers.
Geri Yin: We took a staged or phased-in approach to engage stakeholders and acquire participants to the program. Engagement via the IESO webinars began in December of 2019. Last July the IESO and Alectra jointly hosted a stakeholder engagement session on the detailed design of the Demonstration Program Rules and Participant Contracts, followed quickly by the marketing campaign, where Alectra worked closely with the IESO on marketing and communication strategy. Alectra was taking a customized, one-on-one approach with the customers, helping them understand what the program is about, what they’re being asked to do, and what’s in it for them. We educated customers about the program with our marketing materials and tools. We’re also collaborating with industry associations – such as EDA, OEA, Vaughan Chambers of Commerce, the Markham Board of Trade, and so on, who are also networking and getting the program out through their own channels.
3. Have any of them had to do their own retrofits or upgrades in order to participate? Or were they able to sign up on the spot?
Geri Yin: Some had their resources readily available, some are looking at building DERs. Some will be ready for the second-round market auction next fall.
Jen Hiscock: This sort of approach is extremely transparent in order to allow everyone who wants to play and to allow for broad competition. The project methodology was designed to maximize the breadth of competition, not to create a rush to connect.
4. This is the first such project in Canada. Is there a basic structure to a project like this to help other system operators and LDCs who might want to set up something similar?
Pat Lo: LDCs have their own set of system operations specific to the distribution network – opening and closing breakers, planning system outages – while we’re talking about more market-based constructs, procuring energy resources. So they might have to acquire that capacity, understanding how market systems operate. The IESO’s approach to market operation properly stresses full transparency, including costs, cost breakdowns, rules and contracts. There shouldn’t be anything to hide.
As to the regulatory side, the OEB right now is in a transitional state and they’re looking at more innovation. We’re seeing some good progress. Two of the key takeaways for me are a) the importance of getting to know the markets, and b) learning how to manage the regulatory nuances that will alleviate barriers to developing these new markets.
Geri Yin: Other LDCs may need to work to develop a local energy market perspective. This could mean getting their executives on board, developing the appropriate expertise – in the legal area, system planning, the control room, etc., and making sure the needed processes are established.
They will need a software platform that’s able to register DERs, and allow participants to bid into capacity and energy markets. The system will need the capability for qualifying and contracting DERs, forecasting demand, scheduling, dispatching, performing M&V and settlement, etc. Regulatory changes will clarify and enable the cost recovery for operating this type of local market; but before that happens, ring-fencing the internal resources devoted to the projects (separating them from normal utility business) is necessary so that it will not affect ratepayers.
Pat Lo: The auction has demonstrated that this kind of capacity procurement is fairly economic. This initiative is strategically important.
Jen Hiscock: We always expected a pilot to be a little more expensive than a full scale-up. This pilot will be important as a benchmark. It’s not unusual for people to underestimate the cost of change management at the early stages of a new initiative. There will be a need in many cases to devote time and effort to the development of human resources.
5. What would be needed to make this scale up in Ontario?
Pat Lo: The intent is to take the current wholesale capacity price and compare it to the clearing price of the local auction. That will give us an idea of what resources clear at what level. It will also help us understand what the values are for non-wires alternatives in terms of capital deferral.
FERC Order 2222 is making large strides in the United States. The IESO will be learning from that and likely making moves in that direction as well.
6. Geri, did you have a comment on getting the scale you wanted?
Geri Yin: It definitely required a shift in our thinking about scale. From one perspective we were looking at how to enable customers to have more control of how they use energy. From another perspective we are looking at how to ensure efficient and innovative investment in utility infrastructure. To get to scale, we need to have systems such as DERMS connected to the various DMS at utilities/DSO (i.e., SCADA, GIS, etc.) – allow the DSO to be able to fully integrate the DERs into the grid; be able to control, monitor, manage and optimize DERs, while offering customers grid services to monetize their DERs. Ultimately, we will need a new regulatory framework (i.e., new tariff and rate design/structure) to incent investment in and cost recovery associated with adopting DERs as grid solutions to avoid or defer traditional poles and wires investment.
7. Where is the money for these settlements coming from?
Jen Hiscock: Some of the money for the demonstration project is coming from NRCan funding. And that’s part of why the OEB is happy to have you go ahead; ratepayers aren’t paying for the settlements at this point. But if we want this to get to scale, where will the value come from? Under the traditional TSO approach, we’d only be talking about wholesale clearing prices, but since it’s at the distribution level, we can also add any asset deferrals on the LDC side. So what are the easiest values to realize, in order to minimize administrative costs?
Pat Lo: The way utilities are traditionally set up, it’s often easier for them to rate-base everything. We need to consider if there are other ways to ensure capacity is in place. Can utilities acquire capacity services from market participants for example? Can utility capital be used to secure capacity from DERs, or do we just change the structure entirely to compensate utilities differently?
8. How might anyone considering a role as power producer participate in this project? I’d like to include options for aggregation and behind the meter opportunities.
Pat Lo: We wanted to procure three types of resources, but for this pilot we were only able to organize to get two. There is no storage – that would have been hard to make an investment in given the tight timelines for participation in the first capacity auction. In future we’d love to see some kind of adjustment, so we could see how well it competes.
9. How can future auctions be designed to recognize the lead time that’s often necessary to develop new DER projects to participate effectively? The local region might not have many additional existing assets to leverage.
Pat Lo: This is a two-year market. Typically in such market, once you secure a contract, there’s a short window to get your asset online, six months in this case. For this demonstration project it is not expected to be economic to build new generation. For new resources, we’ll have to consider more enduring programs, possibly with conditional roll-outs. The point here was to gather more evidence about DER behaviour from a system perspective, to determine if this approach would be economic. It appears to be so, and it now seems like we have a good opportunity to push the system boundaries, encourage collaboration with the regulator – and to tie in with climate initiatives as well, as part of a move toward net zero while delivering net benefit for ratepayers.
