| Summary/Abstract |
To meet Canada's emissions reduction targets, governments at the federal and provincial levels have developed climate plans and implemented a series of policies and regulations. Canada's latest climate plan, entitled “A Healthy Environment and a Healthy Economy” aims to decarbonize various sectors of the economy including the electricity sector. In this paper, we explore the extent to which implementing announced policies and regulations could drive investment in the electricity sector needed to achieve Canada's climate objectives. To do so, we propose a multi-period, optimization-based capacity expansion model specifically designed for the Canadian context entitled COPPER for the “Canadian Opportunities for Planning and Production of Electricity Resources.” We employ COPPER to analyze Canada's electricity system transition under various carbon management policies. Results show that current and announced policies significantly increase renewable energy capacity, which in turn decrease the electricity system emissions by 40 percent in the mid-term. However, in the long-term, more ambitious actions will be required to achieve the emissions reduction targets. Natural gas-powered generation facilities persist at the proposed carbon tax levels, and thus supplementary regulations or policies will be needed to achieve deep decarbonization.

| Summary/Abstract |
Concentrating solar power (CSP) integrated with thermal energy storage delivers flexible and dispatchable power, which is an increasingly valuable quality as electricity systems integrate growing penetrations of variable renewable energy. Valuing and compensating CSP's dispatchability and flexibility requires electricity market structures and policies that appropriately remunerate generation during high-value portions of the day. We review previous analyses of CSP economics and deployment, and we find that continued CSP growth will require valuation mechanisms that appropriately compensate for CSP's flexibility during both plant design and plant operation. We then review market structures that drive CSP operations and dispatch in jurisdictions where CSP is being developed, with perspectives from Spain, Chile, Australia, Morocco, South Africa, the United States, China, and the United Arab Emirates (Dubai). Despite broad agreement that CSP's dispatchability provides value to electricity grids, countries' policies for remunerating and leveraging such dispatchability varies widely. As deployment of CSP and variable renewable energy grows, it will be increasingly important to redesign current integration policies to signal the delivery of CSP's grid services more appropriately.

| Summary/Abstract |
Panama recently enacted a new law, which aims to promote wind energy by mandating long term power purchase tenders. The implications of this new law lend some uncertainty to Panama×s electricity development pathway. This paper quantitatively analyzes the current status of power generation in Panama, and explores various potential future scenarios and the associated impacts on the system marginal cost, global warming potential, and resource diversity index. To this end, this study applies the scenario development methodology developed by Schwartz in the context of the energy-economic modeling platform 'Long-range Energy Alternative Planning' (LEAP). Four scenarios are developed and analyzed. The Business as Usual scenario extrapolates the electricity generation trend that has been observed over the last decade; it is compared to three alternative scenarios which have more specific objectives. Scenario 1 encourages climate mitigation without incorporating new technologies in the generation mix, Scenario 2 maximizes resource diversity, and Scenario 3 minimizes global warming potential. For each scenario, the composition of the electricity generation profile, system marginal cost, global warming potential, and resource diversity is predicted quantitatively. These scenarios to not attempt to forecast likely developments, but rather illuminate the tradeoffs that different development pathways entail.
