Summary of country study – Bangladesh 155 What if the electricity price escalates faster?

It represents an initial investment of 35.6 Million Taka and leads to an internal rate of return of 43.5 per cent.
Summary of country study – Bangladesh 156 3.4 Conclusions and Recommendations for Follow-up Actions 1 Conclusion From the pre-feasibility study of the selected sites, one can conclude that thanks to the availability of natural gas distribution network in some economic areas, gas-based cogeneration is found to be the most cost-effective option for Bangladesh. In view of the present national power situation, cogeneration in sites having a steady need for heat and power, and access to natural gas, can improve the production reliability and efficiency while reducing the burden on the already stressed national grid. Moreover, natural gas-based cogeneration will reduce the dependency on imported fuel and will have less adverse impact on the environment. Power demand in many sites is not very high, ranging from 0.5 to 2 MW. These sites are ideal for gas-based reciprocating engines that already have a good presence in the local market. The internal rates of return in all the cases were found to be quite high (above 40 per cent) for the best feasible options, mainly due to the low price of gas prevailing in the country. In spite of the significant techno-economic potential for cogeneration applications in Bangladesh, cogeneration has not been widely adopted in the country due to several reasons. The foremost among them is the low level of awareness at all levels about the technological alternatives, economic merits, environmental benefits and business opportunities related to the application of cogeneration as an efficient energy use option. No systematic study has been undertaken so far to assess cogeneration potential by taking into account factors such as energy demand patterns, plant size, power-to-heat ratio, access to gas pipeline, etc. There is practically no interaction between the energy utilities and the energy users to explore the cogeneration option though the government is serious about encouraging private investment in the power sector. Recommendation for follow-up actions Since cogeneration development seems to be very promising, the hurdles (institutional structure, policy and planning, energy pricing and tariff, investment and financing etc.) in this sector may be removed for its further propagation. Regulatory measures are needed for the sale of excess electricity to the grid or third party, and back-up power supply from the grid as and when necessary. The establishment of a national interagency co-ordinating committee may be seriously considered. Government may also initiate demonstration projects using advanced technologies in selected public sector enterprise in the industrial estates/export processing zones/satellite city centres. State energy suppliers (electricity and gas companies) may play a greater role in the propagation of cogeneration by establishing partnership with potential cogenerators, public or private, in making investment, guaranteeing operation and maintenance, and sharing costs and benefits in the process. 1 These conclusions and recommendations are based on the deliberations of participants in the South Asia Sub-Regional Seminar organized at Dhaka on 14 and 15 November 1998. The programme details of the Seminars are included in Appendix 3A.
