Study Report

Description of Project/ActivityThe introduction of the solar power and long-life battery system (hereafter referred to as “the System”) in off-grid areas of Bangladesh will facilitate the efficient utilization of renewable energy electricity generation and promote wider access to electric power, helping to reduce greenhouse gas emissions (by comparison with conventional fossil fuel based electricity generation). The adoption of this system will also help to improve local people’s living conditions and health conditions.
BOCM MethodologyEligibility Criteria
  • Renewable energy generation means photovoltaic generation.
  • Long-life battery system is charged by PV only.
  • Using Long-life battery that can keep more than 80% recovery capacity after 6,000 cycles by DOD (Depth of Discharge) 100% of full cycle and 1ItA charge and discharge under the specific temperature environment. Long-life battery needs to acquire certifications for product safety standard set by the organization in Japan, United States and EU below.
    JISC / UL / IEC
  • Long-life battery distributes electricity to the
Default ValuesThe average carbon dioxide emissions coefficient (average for all power sources) based on statistical data compiled by the government of Bangladesh is used as the grid power carbon dioxide emissions coefficient (all power sources).
Calculation of Reference EmissionsReference emissions are the carbon dioxide emissions deriving from estimated kerosene lamp usage, from the use of grid power for the charging of mobile phone batteries, and from the use of power generator using fossil fuels in the event that the project was not implemented.
Monitoring Method
  • The only item which requires monitoring is the amount of electric power output from the long-life batteries and supplied to local residents.
  • In this project, the amount of power generated from the solar panels, and the amount of power output from the long-life batteries, is monitored using software, with a framework established in advance to enable the monitoring results to be delivered in CSV format.
  • Monitoring is conducted at a frequency of once a week, with the results generated by the local project supervisor being e-mailed to Sony Energy Device Corporation.
The monitoring results are reviewed by Sony Energy Device Corporation; if there are any abnormal values, on-site verification is performed to determine whether this is due to problems with the equipment or incorrect usage.
GHG Emission ReductionsGreenhouse gas emissions are calculated by multiplying the amount of electric power outputted from the long-life batteries by the carbon dioxide emissions coefficient.
On the basis of the monitoring results, it is estimated that the annual reduction in carbon dioxide emissions is 244-331kg of CO2 per year. While the amount of carbon dioxide emission reduction achievable with a single solar power and long-life battery system is not particularly high, a more significant reduction could be achieved by bundling several such projects together.
Environmental Impactshe potential negative impact of this project on the environment is considered to be very small.
Project PlanThe plan for project implementation is based on an anticipated required initial investment calculated on the basis of the results of a survey that assumes an electric power sales model using “home delivery” of small batteries in off-grid areas.
Promotion of Japanese TechnologiesThe olivine-type lithium-ion iron phosphate cell batteries which constitute the technology/product to be used in the project addressed by this feasibility study provide long battery life, are stable, and do not use rare metals. By exploiting these characteristics, it should be possible to set up an electric power supply system in off-grid areas that is very safe and can operate reliably for an extended period (10 years or more), and to use this to establish a business model for the sale of electric power to households that lack access to mains electricity, thereby creating significant potential for promoting the adoption of Japanese technology.
Sustainable Development in Host CountryIt can be anticipated that this project will make a contribution towards sustainable development in Bangladesh, particularly with respect to the following areas on which the Bangladesh government will be focusing in its development strategy for the period from 2015 onwards: Combating and mitigating climate change; Providing Bangladesh’s citizens with a sustainable energy supply; Ensuring sustainable production, consumption and resource use; Promoting the 3Rs (Reduce, Reuse, Recycle) through effective utilization of products and resources; and Ensuring equality of opportunity for women, and the protection of women’s interests, in the economic sphere.
