Development of Renewable Energy Technologies by BPDB
Government has set up the goal of providing electricity to all by 2020 and to ensure reliable and quality supply of electricity at a reasonable and affordable price. Sustainable social and economic development depends on adequate power generation capacity of a country. There is no other way for accelerating development except to increase the power generation by fuel diversification. Development of Renewable Energy is one of the important strategies adopted as part of Fuel Diversification Program. In line with the Renewable Energy policy 2009, the Government is committed to facilitate both public and private sector investment in Renewable Energy projects to substitute indigenous non- renewable energy supplies and scale up contributions of existing Renewable Energy based electricity productions. The Renewable Energy Policy envisions that 5% of total energy production will have to be achieved by 2015 and 10% by 2020. To achieve this target, GOB is looking for various options preferably Renewable Energy resources. Under the existing generation scenario of Bangladesh, Renewable Energy has a very small share to the total generation. The share of Renewable Energy exceeds more than 1% till now. The present Government is placing priority on developing Renewable Energy resources to improve energy security and to establish a sustainable energy regime alongside of conventional energy sources. Government has already launched "500 MW Solar Power Mission" to promote the use of Renewable Energy to meet the increasing demand of electricity.
Government of Bangladesh has taken a systematic approach towards renewable energy development. In line with the Government approach Bangladesh Power Development Board formed the Directorate of Renewable Energy and Research & Development in 2010. Since the very beginning of establishment the directorate is dedicated to keep a sign for the enhancement of Renewable Energy use in power sector. There is a good scope for solar, wind, biomass, micro/mini hydro power generation in Bangladesh. BPDB has taken systematic steps for developing Renewable Energy projects as well as implement and promote Energy Efficiency Measures for the last few years to achieve the target of the Renewable Energy Policy 2008. The directorate is established for feasibility study, planning, evaluation, examination, monitoring of such projects and to perform necessary research based works in relative fields. Present manpower of the directorate consists of the director, two deputy director, five assistant engineers and six staffs.

Energy Efficiency Measures
For energy saving purposes and encourage the use of CFLs by consumers, free CFL (Compact Fluorescent Lamp) Distribution Program in different offices of BPDB along with headquarter has been conducted. CFLs, T-5 tube light instead of incandescent bulb will be installed in all offices of BPDB in different phases. For the efficient use of energy, steps have been taken to encourage/promote the use of heat reflective glasses for Passive Cooling of commercial buildings, Solar Powered Security Lighting in urban buildings and replacement of Diesel/Electric Pumps by Solar Irrigation Pumps, replacement of Electric/Gas Dryer by Solar Dryer, replacement of Electric/Gas Heater by Solar Water Heater among the consumers of distribution zones of BPDB. In addition to that energy efficiency measures, alternative and renewable energy subjects have been introduced in the national Text Book Curriculum of schools, madrasas and colleges. Energy Star labeling Program has been started by BSTI to motivate the users to use energy efficient appliances. Electricity Week Program has already been launched since 2010 with a view to promote energy savings campaigns at consumer and school level. This program is nationally observed on 7th December each year.
Alongside these projects Directorate of Renewable Energy & Research and Development is also continuing it’s own research works in different renewable energy sectors. At this moment engineers of the directorate are constructing fully operational prototype based Wind Turbine System, Hydro Emulator Set, Solar Power Converter. The wind turbine system consists of three different types of turbine technology including horizontal axis and vertical axis turbine. The total capacity of the system is expected to be 200 W depending on wind velocity. Complete design, assembly and installation of the turbine system has been done by the respective engineers. The Hydro Emulator Set will be a small prototype based hydro turbine system which consists of two different type of turbine technology, Pelton wheel and Kaplan turbine. The turbine system will run from a small water reservoir tank. Generation capacity of the two turbines is expected to be 20 W. The complete design of the Emulator Set has been done by the engineers of the respective directorate. The engineers of the directorate are also trying to design Solar Power Converter with innovative ideas and new concept. All the prototypes will be installed at the concern office Lab.
