Resumen
Descripción
Developing countries are increasingly
pursuing and benefitting from regional power system
integration (RPSI) as an important strategy to help provide
reliable, affordable electricity to their economies and
citizens. Increased electricity cooperation and trade
between countries can enhance energy security, bring
economies-of-scale in investments, facilitate financing,
enable greater renewable energy penetration, and allow
synergistic sharing of complementary resources. This
briefing note draws from the experiences of RPSI schemes
around the world to present a set of findings to help
address these challenges. It is based on case studies of 12
RPSI projects and how they are dealing with key aspects of
RPSI, such as: (i) finding the right level of integration;
(ii) optimizing investment on a regional basis; (iii)
appropriate regional institutions (iv) technical and
regulatory harmonization; (v) power sector reform and
integration (vi) the role of donor agencies (vii) reducing
emissions through RPSI; and (viii) RPSI and renewable energy.
