Railways to Commission 26 mw Wind Mill at Jaisalmer today

Railways to Commission 26 mw Wind Mill at Jaisalmer today

Jaisalmer: With the aim of creating a “green corridor” in Bharatpur-Kota rail section, railways will commission a 26 MW wind mill plant in Jaisalmer in Rajasthan tomorrow.

Railways, one of the biggest consumers of energy, has set up the wind mill plant in Rajasthan to generate 50 million units of electricity per year.

The electricity generated from the plant will be utilised for powering three traction substations – Bharatpur, Hindaun and Ramganj Mandi in Bharatpur-Kota section of Delhi-Mumbai trunk route which will now be the first railway green corridor, said a senior Railway Ministry official.

The project, the biggest renewable energy initiative by the national transporter, is being set up at an estimated cost of about Rs 150 crore.

The plant has been established by Railway Energy Management Company (REMC), a joint venture of railways and RITES.

Harnessing green power, railways is planning to source 1000 MW solar power over the next five years besides establishing a 132 MW wind mill plants by REMC.

Earlier, railways had established its first windmill plant of 10.5 MW capacity at a cost of about Rs 65 crore in Tamil Nadu in 2009. It has generated over 120 million units of electricity since its commission.

As per the plan, railways is also using bio-diesel as energy mix so that long term dependence on fossil fuel can be reduced.

The Netherlands will have 100% Wind-Powered Rail Network by 2018

The Netherlands will have 100% Wind-Powered Rail Network by 2018

The firms that run the railway system across the country will move the entire network over to wind power in the next three years, according to media reports.

Dutch energy company Eneco and the VIVENS rail companies signed a deal to make Dutch electric trains within Netherlands Railways run entirely on energy produced by wind farms. Wind farms already supply half of the 1,800-mile, 1.5kV DC network’s energy-a network that carries 1.2 million passengers a day.

The wind power will come from within the Netherlands, as well as Belgium and some Scandinavian nations; part of the objective is to promote increased renewable energy adoption in other European countries.

Wind power already covers over half of the network’s energy needs and Eneco aims to source source the remaining capacity from the Netherlands and neighbouring countries by 2018.

Eneco account manager Michel Kerkhof said: “What makes this contract and partnership unique is that a whole sector decreases its CO2 footprint enormously and sets an example for other sectors to follow,.”

Kerkhof added: “Mobility is responsible for 20 per cent of CO2 emissions in the Netherlands, and if we want to keep travelling, it is important that we do this without burdening the environment with CO2 and particulate matter. This contract offers all Dutch citizens the option to make a climate neutral trip, regardless of distance.”

The railway covers about 2,890 km and the network is used by approximately 1.2 million passengers per day.

As part of the agreement, Eneco will provide 1.4 terawatt hours (TWh) of wind power capacity by 2018, which roughly equates to the amount of energy consumed by all households in Amsterdam.

About half of the total required capacity is expected to come from sources in Scandinavia and other neighbouring regions, with the rest produced in the Netherlands.

Eneco has used specially built wind farms for the project to avoid putting existing applications under added pressure and to keep costs down.

The railway operators are also making energy efficiency savings by developing innovative train designs and driving techniques to keep demand for energy as low as possible.

Kerkhof said: “This partnership ensures that new investments can be made in even newer wind farms, which will increase the share of renewable energy. In this way, the Dutch railways aim to reduce the greatest negative environmental impact caused by CO2 in such a way that its demand actually contributes to the sustainable power generation in the Netherlands and Europe.”

In the last few years, wind power has seen rapid growth in adoption worldwide. According to the International Energy Council, the land-based wind power installation rate has gone up around 24% annually every year since 2000. The council predicts that if world governments stick to plan, wind power could account for 18% of all energy production globally.

Back in the Netherlands, Eneco says it also entered a 10-year deal with Google to make its data center in the northern part of the country totally powered by wind farm energy as well.

Wind Energy Produced by Metro Trains -Kalindi College

Delhi University students harness Wind Energy produced by Metro Trains

New Delhi: A group of Delhi University students has discovered an innovative way of harnessing wind energy churned out by Metro trains to generate electricity.

The project, undertaken by Kalindi College, has also got the backing of Delhi Metro Rail Corporation (DMRC), which allowed the students to install a turbine on trial basis at one of the underground metro stations.

“While standing at a metro station one day, the students realised that the wind energy produced in the tunnel by these fast moving trains gets wasted, and they decided to find out how it can be harnessed,” says Dr Punita Verma, Principal Investigator of the project.

The team, involving ten students of Physics and Computer Science departments, proposed setting up a turbine at an underground metro station to check if it can be successful in harnessing the wind.

DMRC officials found the project interesting and gave the nod to install a turbine at Chandni Chowk metro station.

“Without obstructing the operation, safety and security of Metro services, it was decided to put up turbine along the underground tracks at the mouth of tunnel where the maximum wind velocity available is 6.5 m/s.

“In the first phase, we installed a three-blade turbine and later a five-blade light rotor turbine with a cut-in speed of less than 1.5m/s. We connected it to a battery and measured the power it generates. We also discovered that different stations have different construction and the same turbines cannot be used at all the metro stations,” Verma said.

The project, which has was started by a different group of students in 2013, has received a grant of Rs 15 lakh from the university.

While the first phase involved the research work, the DMRC engineers were later roped in to test the feasibility, who have asked the team to develop the concept further.

“We are now working on different designs of the turbines whose size, shape and orientation will be customised according to the wind velocity and frequency of trains at different stations. Once the design is approved by DMRC, turbine firms will be approached to make these turbines,” Verma says.
