| Canada’s electrified future is a challenge, but one we can achieveThe growth of electric cars begs the question about the electricity system’s ability to meet the increased demand. But, electrification is not just limited to cars, the electricity sector has the potential to provide low cost and low emissions energy for home heating and an increasing number of industrial processes. Today, our electricity system accounts for just over a ¼ of Canada’s final energy demands, while there is no doubt it will need to grow, the inherent efficiency gains in electrification turn the challenge into one that has been achieved before.

| Alberta’s quiet but resilient electricity transition● Alberta’s phase-out of coal-fired electricity has been an underreported climate policy success, expected to result in a 40 MtCO2/yr reduction in GHG emissions by 2030.
● Mutually reinforcing regulatory and pricing policies at the provincial and federal levels have helped ensure the durability of the phaseout through major political transitions.
● Natural gas-fired generation now dominates Alberta’s electricity sector; the pathway to future decarbonization of the sector remains uncertain.
● While the rapid electricity transition has enabled provincewide emissions reductions in recent years, continued expansion of oil sands emissions threatens Alberta’s progress.

| Improving the value of wind energy through geographic diversity of wind farmsWind farms are often concentrated geographically as they are cited in areas with
strong resources. While this maximizes energy generation, it can decrease the value of
that energy, particularly as the relative amount of wind increases in the overall system.
Wind energy is growing rapidly in Alberta, and this research evaluates the potential to
increase the value of the energy for new wind farms by building them in regions with
lower annual wind speeds but less correlation to the rest of the fleet to capture higher
market prices. The research identifies a trend between the deviation of the location’s
potential generation output from the fleet’s average and the average annual energy
revenue for a wind farm at that location based on data from existing wind farms. This
trend is applied to predict the average annual energy revenue, payback periods, and
internal rate of return for twelve candidate wind farm sites in the northern portion of
the province. | Publication | 2023-02-01 | Taylor Pawlenchuk |
| Market Impacts of Geographic Dispersion of Wind Energy in AlbertaThis thesis presents a methodology to simulate the energy production from hypothetical wind farms in Alberta in order to examine potential future market impacts of a geographically dispersed wind fleet in Alberta. The wind farms’ output are simulated using the Canadian Wind Atlas (CWA) Modelled Historical data (HMD), a publicly available hourly Numerical Weather Prediction (NWP) model and calibrated to historic output from existing wind farms in the province to determine if the data available from the CWA (hourly wind speeds, temperature, and air density), were sufficient to simulate new wind farms in Alberta. A generic loss coefficient was empirically calculated to estimate power output from a wind farm compared to the manufacturer’s power curve at simulated wind speeds from the CWA. By comparing modelled wind farm performance to historical market data from wind farms operating in Alberta, it was found that the CWA tends to underestimate wind speeds from 7:00 am until noon for the spring months, as well as misrepresenting wind speeds for the southwest region of the province (near communities with existing wind farms in Pincher Creek and Fort Macleod). Outside of the southwest of the province, the simulated wind farm’s annual energy production, using the data from the CWA HMD, were within a percentage error between 1% to 10% for wind farms that operated over the same timeframe. By applying this methodology to regions of the province without existing wind farms, the output of new hypothetical wind farms was created in different locations in Alberta. The output of hypothetical wind farms was allows for market impacts simulations of new wind farms in Alberta using the Aurora market model from Energy Exemplar. Preliminary results from Aurora’s model simulation shows that increases in wind energy development will lower market prices during periods of high wind as would be expected. This work enables future analysis examining the potential market changes of a more geographically diverse wind fleet in the province. | Publication | 2020-09-29 | Natalia Vergara Bonilla |

| Alberta’s Renewable Electricity Program: Design, Results, and Lessons LearnedWe present a case study and analysis of Alberta's Renewable Electricity Program, one of a suite of policies implemented between 2015 and 2019 to increase the share of renewable generation in the Canadian province's fossil-fuel-dominated electricity system. The program consisted of a series of reverse auctions for contracts-for-differences which provided successful proponents with a project-specific guaranteed price for power generation. We find that the Renewable Electricity Program was successful in three important ways. First, it contracted for new renewable generation at prices in the range of CA$30 to CA$43/MWh (US$23 to US$33/MWh), well below expectations and among the lowest procurement costs globally at the time. These contracts have resulted in gains to the government of CA$75.5 million (US$60 million) to date. Second, the program ushered new entrants into Alberta's power market, including through mandated Indigenous equity participation in one round of auctions. Third, we find that price discovery and the incentive to develop new projects provided by the program spurred privately-financed development. While the program was a success, we argue that its design did not adequately reward high-value generation, which could have become an issue in future auction rounds. We analyse design alternatives that would have improved the program's dynamic efficiency.

| Deep Reinforcement Learning-based Operation of Transmission Battery Storage with Dynamic Thermal Line RatingIt is well known that dynamic thermal line rating has the potential to use power transmission infrastructure more effectively by allowing higher currents when lines are cooler; however, it is not commonly implemented. Some of the barriers to implementation can be mitigated using modern battery energy storage systems. This paper proposes a combination of dynamic thermal line rating and battery use through the application of deep reinforcement learning. In particular, several algorithms based on deep deterministic policy gradient and soft actor critic are examined, in both single- and multi-agent settings. The selected algorithms are used to control battery energy storage systems in a 6-bus test grid. The effects of load and transmissible power forecasting on the convergence of those algorithms are also examined. The soft actor critic algorithm performs best, followed by deep deterministic policy gradient, and their multi-agent versions in the same order. One-step forecasting of the load and ampacity does not provide any significant benefit for predicting battery action.

| Wind Energy Emissions Displacement in Coal TransitionAlberta's electricity system has undergone a major transition phasing out coal in less than a decade despite the fact it supplied nearly two-thirds of the market when the transition began. Renewable energy is growing as part of this change, including wind and solar. Significant support for wind energy has come from offset credits in Alberta. policy, which credits wind (and other renewables) with a mix of build and operating margin emissions. This paper looks at historic hourly marginal emissions over the past 10 years and to examine how wind energy's emissions displacement has changed over this timeframe and what that might mean for emissions credits in the future.
