Energy Options Assessment
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 COAL COST CROSSOVER: ECONOMIC VIABILITY OF EXISTING COAL COMPARED TO NEW LOCAL WIND AND SOLAR RESOURCES
The report finds that a significant portion of the U.S. coal fleet is now more expensive to operate than replacing it with new local wind and solar power. In 2018, 74% of the fleet was 'at risk' of being undercut by renewables, a figure projected to rise to 86% by 2025. The analysis emphasizes that these findings are conservative because they only consider resources within 35 miles of existing plants and do not account for broader transmission expansion or combined energy portfolios.

COMMENTS ON THE DRAFT INTEGRATED RESOURCE PLAN FOR ELECTRICITY, 2018
The Centre for Environmental Rights (CER) argues that the draft IRP 2018 is unlawful and irrational because it includes 6,732MW of new coal capacity despite its own findings that a least-cost plan would exclude coal. The CER highlights severe failures in the draft, including inflated electricity demand forecasts, outdated and high cost assumptions for renewables and battery storage, and a total lack of consideration for water and climate change externalities. The document specifically objects to the Thabametsi and Khanyisa coal projects, citing their high emissions and risks to water resources in the Waterberg and Highveld regions. Furthermore, the CER criticizes the Department of Energy for failing to conduct meaningful public consultations with impacted communities and for withholding the Plexos modelling data necessary for transparent stakeholder review.

STANDARD BANK’S ROLE IN FINANCING PROPOSED NEW COAL-FIRED POWER PLANTS
The Centre for Environmental Rights (CER), writing on behalf of the Life After Coal Campaign, has called on Standard Bank to cease financing the Thabametsi and Khanyisa coal-fired power stations. The CER argues that these projects are not 'procured' due to missing atmospheric emission, water use, and generation licences, and are subject to High Court reviews. The document asserts that the 2018 draft Integrated Resource Plan (IRP) incorrectly includes these projects despite a 'least cost' option consisting only of solar, wind, and gas. The CER claims the projects would cost South Africa nearly R20 billion more than necessary, increase electricity prices for consumers, and exacerbate severe health issues in the Waterberg-Bojanala and Highveld Priority Areas. Furthermore, the CER highlights that these plants would have greenhouse gas emission intensities 'almost 60% higher than Eskom’s Medupi and Kusile power stations', undermining South Africa's Paris Agreement commitments.
