| Summary: | Integration of large-scale variable
renewable energy (VRE) generation resources -- wind and
solar -- into national grids has been gaining importance as
costs of these technologies, especially that of solar,
continues to fall rapidly. However, there continues to be a
lack of a framework to systematically analyze the role
played by large-scale VRE integration for most developing
countries. This study develops such a framework and applies
it to analyze VRE policies in Bangladesh. The study uses a
least-cost planning approach to assess the volume of solar
and wind that can technically and economically be integrated
in the power system, accounting for spinning reserve
generation capacity requirements and adequacy of
transmission capacity. The study shows that solar and wind
can provide a significant share of the 13 to 21 GW of new
capacity needed by 2025 to meet rapidly growing electricity
demand, although most of it does not pass the cost/benefit
test in the near term till 2022. Efforts are also required
to cope with what otherwise would be a large and costly
increase in on-demand ("spinning") reserve
capacity. The analysis demonstrates how an investment
strategy to cover peak demand, and prudent changes in system
operational practices, allow for the system to provide the
needed reserve capacity without a prohibitive increase in
system costs. In addition, the study examines the adequacy
of transmission capacity for the first large-scale solar and
wind project in Bangladesh. |
