Riding the wind


RUBEENA MAHATO


Even advocates of renewable energy gave up on the prospect of wind power in Nepal when the two 10KW wind generators in Kagbeni and Mustang were blown away in 1989. The damage extended beyond that to the generators. In the years to come, no serious efforts were made either to repair the plant or to set up other projects on such a scale. Complications with other wind projects reinforced the idea that wind power was not viable in Nepal.

So it was no less than a breakthrough when in 2009 a group of students from an engineering college in Kathmandu set up a 2KW wind turbine, using their own resources. The turbine that stands tall on the roof of Kathmandu Engineering College in Kalimati (pic, above) generates enough electricity to power the computer lab and library of the college and is much more powerful than most wind turbines set up by the government and NGOs across the country, most of which produce 200-600W for lighting purposes only.

"It took us little more than a month to set up the turbine. We used locally available materials, some of which even came from the junkyard, and built a fully functioning wind power plant at a very reasonable price. We wanted to prove that wind power can work in Nepal," says Amrit Singh Thapa, who led the group. The same year, they went on to set up the tallest turbine in Nepal, a 1.5KW generator at a resort in Lakhuri Bhanjyang (pic, below), and now Thapa heads a private company that promotes wind energy.

According to a study by the Alternative Energy Promotion Centre (AEPC), Nepal has the potential to generate 3,000MW from wind energy, with the Kathmandu Valley alone capable of producing 70MW. On average, Nepal gets 18 hours of wind every day and at least two good windy days a week, and in some places like Kagbeni, 200MW could be generated from a single plant. Along with private firms and development organisations, the government too has shown interest in tapping into this resource.

With the declaration of 2009 as alternative energy year, the government announced a program to generate 20MW of electricity from wind energy in and around the Kathmandu Valley through public-private partnerships. There are also plans to build a model wind farm of 500KW and provide assistance to small-scale wind turbine manufacturers generating less than 10KW. But though a 20MW wind project is in the pipeline, government officials say the focus for the time being will be on smaller rural projects of a few hundred watts rather than utility-scale projects.

Many experts rightly point out that wind or solar power can never be an alternative for hydropower, especially in a country like Nepal. But relatively quick and easy installation can make wind power plants a feasible option for places unconnected to the grid where micro-hydropower plants are not possible. "The government's policy is to promote wind power in places where wind can be harnessed and communities can be given some respite before the grid can make it there," AEPC's Narayan Adhikary explains.

The private sector, on the other hand, is also eyeing urban areas as a potential market. "We are looking into building a wind power plant near the Kathmandu Valley. And unlike the government, we want to go beyond a few kilowatts," says Thapa. Ram Poudel, lecturer at the Institute of Engineering in Pulchok, says that technically this is not a problem, "In places where wind readings are high, wind power can be more cost effective than other renewable sources. As much as 10MW of electricity can be produced in eight months if all conditions are met, which is of course much quicker than hydropower," he says.

The private sector says the government should at least create an investment-friendly environment for companies willing to invest. "The national wind policy, the draft of which was prepared months ago, has not been finalised," says Thapa.

Nischal Shrestha of Krishna Grill Engineering Works, Mandikhatar, echoes this concern. "We know that there is an immense possibility for wind power but investors will not move forward unless there are proper policies and provisions in place." Adhikary concedes: "With the data we have now, it will be very hard to draw in foreign investors."


Energy village

More than 60 per cent of Nepal's population has no access to electricity. Only 33 per cent, mostly in urban areas, is supplied power from the grid, and 7 per cent derive electricity from alternative energy sources. For the rest it is perpetual darkness once the sun goes down.

Given the power shortages in the capital, remote rural areas have a long wait ahead. Where micro-hydropower plants are not feasible either, the grid could take decades to arrive.

But Thanatole, a small Magar settlement, in Nawalparasi, is proving that hydro isn't the only renewable energy source on the block. Wind and solar power in Hurhure Danda (pic, right) is generating 600W of electricity for the 45-household community, which uses this power for lighting and to charge mobile phones. "It would have taken at least another 10 years for this village to be connected to the grid. Projects such as these, albeit small in scale, will at least ease their immediate power needs," says Surbir Sthapit of HICODEF, which has been implementing this project with the support of Practical Action.

The project is not without its problems. The wind turbines have been acting up and the community is relying solely on solar for the moment. "Mostly problems arise due to poor manufacturing and the lack of proper repair and maintenance in remote areas," Pushkar Manandhar of Practical Action says. "But because we have installed a hybrid system, one system can provide continuous supply when there are problems with the other." Practical Action has built 23 wind turbines across the country.

Hurhure Danda is also being developed into a model energy village. There are plans to set up ten biogas plants and provide villagers with improved cooking stoves that minimise indoor pollution and are more energy efficient.

What the hell ? We don't need Wind power in Nepal you know why ? Becoz we are happy to be in the dark . Crap!

2. Suraj Thapa
We are proud of you bro Amrit Singh Thapa. Keep it up...

3. bandhuraj
What is the cost to build 2 kw ?

4. MS
Email of Mr. Thapa would be nice. Articles like this should always provide contact information of person/ngos/companies.  

Thanks

A balanced view on wind power.  Great that Ms Mahato does not push wind power as the panacea of the power crisis in Nepal. Thank god. Solar or wind, nothing can ever compare to hydro and the reporters who go gaga over alternative energy without understanding the basics need to learn the abcs first.

Like the idea of promoting wind in off grid places without scope for micro hydro. And Ms Mahato's signature style of showing people taking the lead is great as always.

Way to go Mr. Thapa and all the students who built the turbine.

Modern large wind turbines can be over 10MW capacity. That is 10,000 the size of these toys.

Even these large units are quite uneconomic because they only provide about 30% of their capacity due to variability of wind. The other 70% of the time has to be met by conventional generators anyway.

Like solar, wind is promoted by green INGOs mainly to reduce carbon emissions which has no importance in Nepal and is exceptionally stupid in Nepal where the power replaced would be from emissions free hydro.

Wind power generation  time is short comparatively and most of the  manufacturing  works can be done in Nepal. It can be justified due to the urgency of power.  Poor Nepal how long you can afford these snobs in the saddle? NATOs( No action talk only)
 However no country should depend only on on source  of power.
 Important thing is the proper mix of various sources of power and Nepal cannot be an exception
