“…People and communities can develop towards modern civilization if electricity is made available because it can benefit their lifestyle by improving the level of health, education, economy and technology [1]. Renewable energy technology system is recognized as the alternative technology to grid electricity network and solar photovoltaic (PV) system is a popular option [2].…”

Abstract-In 2006, there was a significant numbers of schools in rural Sabah in Malaysia that had no access to 24-hours electricity. Extension of grid electricity networks becomes uneconomical because of the geographical conditions of these areas and the low electrical energy density demand of the population. Malaysia's rural development policies, therefore, emphasizes on the need to improve the learning and living condition at the rural schools. The abundant solar energy resource in the region is used for providing alternative power supply for these schools. 160 schools in rural Sabah were installed with solar photovoltaic (PV)-diesel hybrid systems. Even though the systems have been in operation for some years, knowledge informing the systems performance is difficult to find. Thus, understanding the system operation is a highly valuable experience and lessons can be learned for implementation of the rural electrification program (REP). This paper describes the finding from a field study at 11 solar PV-diesel hybrid systems. It highlighted some parameters that define the reliability of a solar PV system. The solar PV systems installed at schools in rural Sabah were found to be reliable. They reduced dependency on the diesel fuel consumption and fully utilized clean energy from the sun. It is essential to have reliable solar PV system that can provide sufficient energy for the load demand.

Citation: MOURSHED, M., 2013. Pitfalls of oil-based expansion of electricity generation in a developing context. Energy Strategy Reviews, 1 (3), pp. 205 210. AbstractIn the context of growing demand and the need to rapidly increase access to convenient forms of energy, developing countries face many challenges for the development and upgrading of national energy infrastructures. Constraints on primary fuel sources, lack of capital and socio-political dynamics often result in the adoption of sub-optimal strategies for the expansion and upgrading of the existing infrastructure. Bangladesh is one such example that recently initiated a 10-year expansion program in 2010 to treble its generation capacity to 20 GW by 2021. The majority of about 3 GW capacity increase in the last two years has been based on imported oil such as heavy fuel oil (HFO) and high speed diesel (HSD). Despite having surplus generation capacity in 2011-12, the country continues to experience blackouts almost on a daily basis. By analysing the profiles of electricity demand, generation and shortage, as well as fuel imports, this study on Bangladesh demonstrates that increasing oil-based generation capacity does not always result in a proportionate increase in net electricity production. Moreover, increased dependence on volatile international energy markets for sourcing of fuel results in greater macroeconomic risks. Such macro-scale stress in a developing economy can be counter productive for social and economic development, as it takes resources away from other important sectors. Outcomes of this study can be useful for other developing countries that are undertaking energy sector reforms.

“…This will have serious consequences for energy security as the existing electricity infrastructure in Bangladesh is deemed as inadequate even to meet present demand. Only 43 % of the population is served by the grid and per capita electricity consumption in 2007 was 143.6 kW·h, which was one of the lowest in the world [43]. Electricity consumption is likely to increase with the growth in gross domestic product (GDP) and income.…”

The impact of the projected changes in temperature on heating and cooling requirements in buildings in Dhaka, Bangladesh

Dhaka, the capital of Bangladesh, is a fast growing megacity with a population of 12.8 million. Due to its tropical location, dense urban morphology and higher than average density of population, buildings in Dhaka are likely to be adversely affected by the projected changes in climate, in particular by the increases in temperature. Buildings play a vital role in most aspects of our lives and their energy consumption patterns affect climate change mitigation and adaptation strategies. It is important to understand the likely impact of the projected increases in temperature on cooling and heating requirements in buildings in future climates. In this research, global projections on changes in temperature are temporally downscaled using a statistically averaged baseline present-day hourly weather data to generate future weather data in three timeslices: 2020s, 2050s and 2080s. Time series data for the present-day and future climates are analyzed as well as heating and cooling degree-days are calculated. Analysis shows that heating degree-days decrease whereas cooling degree-days continue to increase in future climates. The magnitude of change in monthly cooling degree-days is uneven and is greater in winter months than in summer and monsoon. Increased occurrences of temperatures above comfort threshold throughout the year are likely to have significant consequences for human health and wellbeing. The severity and duration of outdoor temperatures in the form of increased cooling degree-days in future climates will result in a surge in demand for energy for comfort cooling, which will add further stress to the already stressed energy infrastructure in the country. Prompt actions from stakeholders are, therefore, essential to enhance the resilience of Dhaka's buildings to climate change.
