NDMC to adopt solar in a big way ...!

New Delhi Municipal Council (NDMC) will appoint an operator to identify, design, erect, install, test, and commission rooftop solar units as defined by the Union Ministry of New and Renewable Energy. After the installation of the solar rooftops, New Delhi would become the second solar city in the country after Chandigarh.

NDMC has identified 40 buildings in the area under its jurisdiction for installation of rooftop solar panels, its chairperson Jalaj Shrivastava has said. It will save NDMC from taking formal permissions at different levels while implementing this project.NDMC expects to generate almost 8MW rooftop solar energy within a year.

According to an MoU signed between NDMC and Solar Energy Corporation of India (SECI), the civic body should meet at least five per cent of its total energy consumption needs through solar energy.

As per estimate, the NDMC area consumes a daily 350 MVA electricity during summer and 150 MVA during winter. Apart from this the civic body is also contributing 16MW of electricity to 8,000 households in the city by generating power using solid waste as fuel at a 'Waste To Energy' plant on NDMC land in Okhla. 

One question remains - if the New Delhi streetlights come under the NDMC purview, would solar streetlights help save energy, and add to the quote of solar power generation as mandated for NDMC ? This has twin benefits - generation of power, and helping keep the roads lit up even when grid electricity fails ( which now is happening at regular periodicity) is one. The other is what we believe is 'solar technology visibility' for the common man to see. We believe that we are at the threshold of a strong revolution that is brewing. And solar technology adoption is going to skyrocket. What needs to be done is popularise its usage and have enough working prototypes available for people to see and learn from.

New Delhi Railway stations to produce solar power

The  Indian Railways is planning to generate 1 MW solar power at the New Delhi railway station by installing solar panels on the platform roofs. It would be implemented on a public-private partnership model was a part of the railways' initiative to convert some of its stations into "green buildings". It will be developed as per RESCO model in which an agency develops whole infrastructure and client pays the cost of electricity consumed per unit.

The New Delhi railway station is spread over an area of the 6,38,467 square metre, including the yard area. About 4,21,388 square metre of the total is built-up area. The station has 16 platforms.
Once operational, about 25 per cent of the energy requirements at the New Delhi station can be met by solar power, which has an average daily demand of over 4 MW. This is way above the utilities are mandated to generate as milestones fixed.

The Railway officials said that once the pilot project at the New Delhi station becomes successful, it would have a model that could be replicated at other stations in the city viz.,Bijwasan, Old Delhi, Nizamuddin, and Anand Vihar. One wonders, why it needs to stop there and replicate this in other smaller railway stations. One risk is of pilferage and maintaining the systems in smaller locations such as Tier 2/3 towns and cities in India and the Indian Railways decides to go solar in such locations. Priority needs to be accorded to locations where grid power is erratic and in short supply.
