Hybrid Solar Plant Comparisons in Ontario: Implications for Canadian and Global Development and Investment Strategies
Bibliographic record
Abstract
Anthropogenic climate change is driven by the emissions of greenhouse gases (GHG). To limit global warming to 1.5°C above pre-industrial levels and satisfy growing global energy demand, new sources of energy with low GHG emission levels must be developed. Furthermore, at a national level, Canada is not close to meeting its GHG emission reduction targets under the 2015 Paris Agreement. Hybrid solar power plants have been identified as a potential source of reliable, abundant, and environmentally friendly energy. By combining energy sources, hybrid power plants are able to overcome issues such as intermittency and excess electricity that are typically associated with renewable energy sources. However, significant logistical and contextual questions remain concerning the best strategies for hybrid energy development at the national and international levels. This research used hybrid modelling software (HOMER Pro) to perform a direct comparative analysis of the performance and efficacy of a series of different hybrid solar power plant designs. The study compared a variety of hybrid solar power plant designs (using solar, wind, batteries, and fossil fuel generators) on the basis of three equal factors (GHG emission reductions, power generation and reliability, and cost-effectiveness), under the same environmental conditions and location (Peterborough, Ontario). The modelling results showed that the hybrid solar power plant designs H5 (PV-BAT-DG) and H10 (PV-BAT-NG) performed best across all three primary factors of analysis. H7 (PV-Wind-BAT-DG) and H11 (PV-Wind-BAT-NG) produced the lowest quantities of GHG emissions among all of the hybrid solar power plant designs. Canada and countries with similar pollution pricing measures should invest in H7 (PV-Wind-BAT-DG) and H11 (PV-Wind-BAT-NG) hybrid designs in order to maximize GHG emission reductions and develop, diversify energy resources, and service increasing long-term energy demands. Countries that are more concerned with short-term cost-effectiveness as well as reducing GHG emissions should focus on the H5 (PV-BAT-DG) and H10 (PV-BAT-NG) hybrid designs.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
