Energy Assessments and Strategies | New Approaches to Power System Planning

Model for Electricity Technology Assessment Tool




The Model for Electricity Technology Assessment (META) facilitares the comparative assessment of the economic costs of more than 50 electricity generation and delivery technologies, including conventional generation options (thermal, hydroelectric, etc.), nonconventional options (renewables), and emerging options such as power storage and carbon capture and storage (CCS). META has an option for incorporating the costs associated with externalities in power generation such as local pollution and Green House Gas emissions. The META model can also be used to udertake uncertainty analysis for selected key inputs. META is populated with default performance and cost data inputs drawn from three representative countries: India, Romania and the USA, which were chosen as proxies for developing, middle-income and developed countries, respectively. Users also have the option of customizing the data for new countries by entering detailed input data directly into the model and for as many parameters as they consider necessary.





Electricity Sector Planning in an Era of Private Sector Participation and Increased Risk





The electricity sector is becoming increasingly more complex. Many countries that have initiated the restructuring process face challenges in completing the process. Often, power generation is in the hands of a multitude of entities, some public and some private. Even in vertically integrated systems, the sector faces greater complexity and challenges. The sources of generation are more diverse than in the past decades with greater reliance on renewable resources. In parallel, the range and scale of risks that can impact costs and benefits of electricity investments has expanded. The risks faced by electric utilities have all increased in recent years. World commodity markets, including for oil, are seeing increased levels of uncertainty. Risks associated with environmental (including extreme weather events and carbon markets) and social aspects are becoming more pronounced. Countries are increasingly taking climate change considerations of their decisions in the electricity sector into account and taking measures to mitigate greenhouse gas emissions In this context, ESMAP is collaborating with the Energy Practice of the World Bank on a three year power system planning support program to help client countries integrate new and emerging topics in power system planning such as risk, climate change, variable renewable energy, and institutional and regulatory arrangements planning in a decentralized market based environment. In particular, ESMAP will provide support for training on these advanced topics in planning as well as technical assistance to countries to integrate these concepts in their power system planning.


International Experience with Open Access in Power Grids





In response to demand from regional clients, ESMAP has launched a study on different approaches to private sector participation in electricity transmission and distribution grids, and the design and implementation challenges of open access to transmission and distribution systems. These two areas are receiving attention from policymakers in the developing world, on account of the substantial investment needs in transmission and distribution, and the growing need to enhance the efficiency of the power sector. This work draws on lessons gained from international experience in these areas, along with a closer look at the progress on private participation and open access in five key countries—Brazil, Peru, Turkey, India and the Philippines. The outputs of this study are expected to assist other countries that are looking toward private participation and increased open access as necessary factors for improving the efficiency and reliability of their power sector.
