Meanwhile, countries need to continue to strengthen underdeveloped grid infrastructure to realize the full potential of distributed energy. A comprehensive, well-aligned, and stable policy atmosphere is needed to create a favourable investment environment. The Regulatory Indicators for Sustainable Energy scoring methodology set by the World Banks Energy Sector Management Assistance Program (ESMAP), indicates that many Asia-Pacific countries are not in a strong position to effectively mobilize energy investments (figure 4.10). The uptake of renewable energy is hindered by inadequate grid systems required to transmit energy from supply to demand centres and to provide sufficiently broad balancing areas to handle the variability of generation from resources, such as wind and solar.
