Deployment of renewable energy technologies in Bangladesh: Long-term policy implications in power sector

摘要

This paper presents an assessment of future energy-supply strategies for the Bangladesh power sector. It identifies the prospects for the further economic development of the country while ensuring energy security and mitigating environmental impacts. The MARKAL standard version is used to model Bangladesh's power sector including already existing as well as innovative energy conversion technologies. Different policy scenarios for the evaluation of the power sector from 2010 to 2035 are explored. The analysis shows that Bangladesh will not be able to meet the future energy demand without importing energy. However, alternative policies like CO_2 emission reduction by establishing a target, or accelerated deployment of renewable energy technologies reduce the burden of imported fuel, improve energy security and reduce environmental impacts. The model predicts that alternative policies will not result in significantly higher cumulative discounted total energy system cost. The system cost increases up to 7.7% over the base scenario. The alternative policy scenarios reduce imported fuel by up to 100%. Renewable energy technologies, especially solar photovoltaic play an important role in achieving reasonable energy security.
