Eco-Friendly System

Our Projects minimize the amount of greenhouse gasses that are produced as a by-product, to keep the environment from dying.

Electricity Generation

We try to work with all we have to produce as much energy as we can to help sustain the country and its people

New Technology

We are using newer technologies to further increase the quality and quantity of our production in a significant manner.

Message from Executive Director

Nepal is a small mountainous country bordering between India and China. At the Northern part of the country there are high Himalayas and mountains whereas at the Southern part it is flat land. The Himalayas are the perennial sources of water that can be used for drinking, irrigation and electricity generation. With the magical topographic variation within a small distance and perennial sources of water there is ample opportunity for hydroelectric power generation.
Power generation through private sector has been opened after the introduction of Hydropower Development Policy and Electricity Act in 1991. Since then within a short span of time, the contribution of electric power in the national grid by private sector has remain significant. With this policy reform we were able to build and operating three hydropower projects, Piluwakhola (3MW) at Sankhuwasabha district, Ridikhola (2.4MW) at Gulmi district, and Rairangkhola (0.5MW) at Dhading district, Nepal.

Nepal is facing power deficit, hence, there is scope for power generation from public and private sector. If additional energy generated from the projects it can also be sold to the neighboring country. The company is working to build new projects. The contribution of electricity generation through private sector and government needs higher effort as Nepal is facing power deficit. Hence, there is ample scope of developing hydroelectric projects. If additional energy generated from the projects it can also be sold to the neighboring country. The company is working to construct 9900kW Iwakhola Hydroelectric Project, located at Eastern part of Nepal.

Power is the basic infrastructure for economic growth. In order to support the country's deficit power, I request to the interested parties for the investment in hydropower projects in Nepal. Our motto is "Power Generation through Peoples' Participation". We request you to join hand by investing in hydroelectric projects




Ridi Hydropower Development Company is a limited company registered under the Company Act of the Government of Nepal. It is established in 2000 AD with a mission to develop, own and operate hydroelectric project. The company has built and operating a 2400kW Ridikhola Small Hydropower Project at Ruru VDC of Gulmi district, Western Development Region of Nepal. The motto of the company is "Hydropower through Peoples' Participation". Ridikhola Project is an example. There are 300 promoters shareholders in the company with a minimum investment range of Rs. 10,000 (US$ 133.33). Of the total number of promoting shareholders, around 50 percent shareholders are from the project area.

The company is formed by a team of experts. The Company has been developed as an umbrella company of Arun Valley Hydropower Development Company Limited that has already built and operating a 3MW Piluwakhola Project in Eastern Nepal (visit We have a complete team to design, construct and operate hydropower project project. We want to share our experiences to the upcoming project developers as well as provide technical support.

The company is planning to develop other hydropower projects in future. Based on our experiences of project development and operation, we also provide training, consulting facilities for detailed feasibility study, detail design, construction & supervision, environmental study, etc.

Dams are primarily used as a recreational lake. But when there is the need of generating electricity, the water in a this reservoir is controlled by a control Gate. Gates on the dams open and gravity pulls the water through the penstock, a pipeline that leads to the turbine. Water builds up pressure as it flows through this pipe moving the turbine.


The Turbines moves due to the pressure of the flowing water. This generates kinetic energy which is converted into usable electric energy in the generator. This is sent to the Transformers at power stations, which produce very high voltages needed to transmit electricity through the National Grid power lines. This is because high voltages improve efficiency by reducing heat loss in the power lines.

Hydro Power line

The Power lines move electrical energy from the generating site, in the power plant, to an electrical substation in bulk. This movement is facilitated by a transmission network. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is known as the "power grid".
