TECHNO-HILL ENGINEERING CO., LTD: GRID EXTENSTION OF SOLAR MINIGRID DEVELOPMENT AT KENTI ISLAND
In June 2016, World Bank and the Department of Rural Development (DRD) announced the 1st Mini-Grid Call for Proposals as part of the National Electrification Plan framework to private mini-grid developers.The aim of the project is to support rural electrification in order to contribute to stimulate the social and economic development of the country.
Techno-Hill conducted a detailed site survey and collected data by meeting with village people to understand the requirements of the village, etc. It submitted a proposal that was screened by an evaluation panel comprised of national experts from DRD, international experts from GIZ and the World Bank. Techno-Hill was selected to develop a 63kW Solar Mini-grid at Kenti Island located at Southern Myanmar. A feasibility study was also presented to GIZ and DRD as part of the project award process.
This Project will be under PPP (Public-Private- Partnership) program. World Bank and DRD subsidized the 60% of project value, Techno-Hill to invest 20%, and village to contribute 20% of project value.
The Project site is Kenti Island in the Tanintharyi Region, Southern Myanmar. There are 600 households in the village. The major sources of income are from fishery, plantation, farming, shop owners, small workshops (welding/grinding to minor repair of ships/boats) and rice mill.
Testing and Commissioning was completed and operations will begin on the 1st week of July 2017. Techno-Hill is now going to extend the existing plant to electrify whole Island.
Techno-Hill has done similar Mini-Grid Installations at Shan and Chin states for a total 11 sites and also, installation works for Solar Telecom sites, rooftop solar system, and other electrical installations in commercial buildings as well. Techno-Hill will continue to develop more Mini-grids at various islands and states in Myanmar this year and has initiated collecting data and conducting site surveys.
What problem are you trying to solve? Who has this problem?
There is an existing 50kVA generator owned by a private individual. Current Tariff rate is 650Kyats USD 0.6/kWh and there is minimum unit usage (10units/month). That means the villagers need to pay minimum of 6,500Kyats (USD6) per month regardless of utilizing full units or not.
There are around 600 households in the island. Currently, the villagers can access electricity only 4 hours at night time. Most of the villagers prefer to access the electricity for more hours per day.Since it is an island, it is difficult to connect the grid within the next 10 years.
There is an existing Rice Mill, workshops (minor repair for ships/boats), beauty/hair saloon, some fish/prawn ponds which need oxygen supply, water pumps, shops, photo printing service, etc., Some villagers want to start photo copy machine in their shops once they can access more reliable electricity from the Mini-Grid in future.
The community can develop the following livelihood activities and community services once there is sufficient electricity that can be distributed throughout the village:
1) Telecom Services (there is no telecom tower in this island and some of the area cannot receive the network coverage) BTS Lamp Pole Solution and Charging Station can be considered.
2) Cold storage or Ice making machine
This will be very useful in the future for development of economy for this region.
3) Computer center, School Library and Senior Citizen Corner
This is required as this island is far from mainland. There is an average of 4~5 children per household which is rare in the city area. They are our future and we need to enhance the environment for their development.
4) Energy Savings Household Appliances
To bring in some Electrical/Electronics Products distributors or manufactures or companies to invest in community development program. And to educate the villagers to use more energy efficient appliances and become the distributor or shop owners.
5) Implementation of Environmental and Social Development Program/System
To implement environmental control systems such as sewage treatment, water pumping station for households and farming, seawater treatment system, and other control and monitoring system related to environmental management that require electricity.
6) Inviting Banking System for local area trade development program
Most of the households business are selling the fishery products, running shops, and farming. Trading and business will enhance if there is a bank or similar financing institution that will setup in the Island.
Techno-Hill conducted the household and village survey to find out the actual usage and future demand of the electricity. Then, proposed to develop 63kW Solar and Diesel hybrid system as per below system configuration:
Solar-Diesel Hybrid Minigrid Detail:
Minigrid sizing – 63kW
Numbers of Household – 300 Households
Commercial load – 10 nos. of water pump, 1 rice mill, 2 workshops
Community load – 2 schools, 1 clinic, 30 streetlights, 2 monestries
Average Electricity Operation Hours per day – 8 hours
Total years of operation – 8 years
Metering System – Prepayment Meter Solution
Plant Area – 2 Acres
Bill of Materials:
252 x solar panels (250Wp/panel) including solar structure (Schneider Electric)
48 x 3000AH batteries (Schneider Electric)
95 x Distribution Concrete Poles (Local)
1 x 50kW Generator (Weichai)
6 x Inverters (Schneider Electric)
14 x Charge Controllers (Schneider Electric)
Distribution boxes, Cables and Household wiring/meters, etc., - Power house
Local Business Investment or Development.
Our vision for developing the Mini-gr...
Provides modern energy access to 300 households.
Creates 160 new jobs during the lifetime on the project.
Improves the health conditions of 2,000 people.
Out of the total number of beneficiaries of the project, 400 are women.
We had formed Village Electricity Committee with 11 villagers and able to train them for the Solar - Diesel Hybrid system and operation.
We also tried to setup a road show at schools, as well as going to train the students who are interested in renewable energy to come as an energy ambassador.
Now people can enjoy streetlights at night, household lights for night and morning time, students can access electricity during school time, lights at monastery and clinic, etc.,
Sooner, the villagers will have opportunities to startup their home business such as photocopy and printing, shops, computer center, etc.,
