The report finds that transitioning from the current vertically-integrated monopoly structure to a competitive RTO in the Southeast would generate approximately $384 billion in cumulative savings by 2040. This shift would lower retail electricity costs by 29% and reduce carbon emissions by 37% relative to 2018 levels. The analysis highlights that competition accelerates the deployment of wind, solar, and battery storage, creating a net increase of 285,000 jobs compared to the business-as-usual scenario. The study contrasts this with the current Integrated Resource Plan (IRP) approach, which it characterizes as inefficient due to excessive reserve margins and a reliance on uneconomic coal generation.

The report evaluates Nepal's future energy options, finding that while hydropower remains central, integrating wind, solar, and battery storage can enhance system flexibility and support river conservation. Using the SWITCH model, the study demonstrates that strategic conservation of rivers, such as the Karnali basin, can be achieved with minimal impact on overall system costs. It also highlights the risks of relying solely on hydropower, noting that such a strategy increases costs by 10.7% and requires significant overbuilding of capacity to meet dry-season demand. The analysis further indicates that imports from India are critical for affordability, as eliminating them would increase system costs by approximately 45%. Additionally, the report explores regional equity and export strategies, suggesting that a diversified energy mix can support social goals and potential profitability if export prices exceed 30 $/MWh.

The CSIR's analysis of South Africa's Draft IRP 2016 concludes that a 'Least Cost' scenario—prioritising solar PV, wind, and flexible power—is significantly cheaper, creates more jobs, and emits less CO2 than the government's Base Case and Carbon Budget scenarios. The report argues that the Draft IRP 2016 imposes annual new-build constraints on solar and wind without techno-economic justification, which artificially inflates costs and pushes the system toward new coal or nuclear investment. By 2050, the CSIR finds that a renewable energy share of over 70% is cost-optimal. Technical assessments on system inertia and transmission infrastructure indicate that the costs of maintaining stability in a high-renewable system are low, representing less than 1% of total power generation costs.
