Jakson commissions rooftop solar plant for IT ministry
A 200-kw rooftop solar plant commissioned on Electronics Niketan Building in New Delhi was recently inaugurated at the hands of Union Minister for Law & Justice and Electronics & IT, Ravi Shankar Prasad. Installed and commissioned by Jakson Group, this rooftop solar plant will help generate up to 3,00,000 kwh of electricity every year and reduce emissions by 216000 kilograms per year, a release from Jakson Group said.
Electronics Niketan Building houses the National Institute of Electronics & Information Technology, an autonomous scientific society under the administrative control of the Union ministry of electronics and information technology.
As part of the project, Jakson, installed 669 solar modules of 310 watt manufactured at its state-of-the-art solar module manufacturing plant in Greater Noida. In addition to turnkey engineering, procurement and construction services for the project. Jakson will also provide annual operations and maintenance service to the plant for 25 years, the release said.
The project was executed under Solar Energy Corporation of India’s RESCO scheme. Under the Renewable Energy Service Company (RESCO) model.
RESCO model
Under the RESCO (or OPEX) model, the consumer installs a solar power plant without any upfront investment. The RESCO makes the entire capital investment to install and commission the plant. The RESCO then sells electricity generated from the solar plant to the consumer, at mutually-negotiated rates and under a long-term power purchase agreement. The RESCO recovers its investment and makes profit from the electricity sold to the consumer. The consumer, in turn, profits from displacing at least some proportion of expensive grid power by cheaper solar power.
Indian Railways adopt solar rooftop system for diesel-run train
- Jul 15, 2017
Jakson Group, in a release, said that it has become the first company in India to successfully commission a solar rooftop system with battery storage on diesel-run train. The 1600HP Diesel Electric Multiple Unit (DEMU) coach of Indian Railways, which was equipped with solar-powered hotel load system installed by Jakson Engineers Ltd, was flagged off by Railway Minister, Suresh Prabhu, on July 14, 2017, from the Safdarjung Railway Station in Delhi.
The project will help offset carbon emissions by 9 tonnes per coach per year and also save about 21,000 litres of diesel for a solar-powered DEMU with six trailer coaches, thereby bringing cost saving of Rs.12 lakh every year. This is the first instance of a diesel-run passenger train fitted with solar rooftop system with battery backup. The system is capable of developing up to 20 kWh per day throughout the year. Surplus power generated during peak hours will be stored in a 120AH battery system. It will help in generating useful data for research for adapting the system for future rollout on all trains of Indian Railways. The solar system has been fitted with anti-theft mechanism which can withstand trains running with a speed of more than 100 kmph, the release said.
Jakson was awarded this project by the Indian Railways Organization for Alternate Fuels (IROAF), a unit of Indian Railways that works to promote bio-diesels and other environmentally benign alternative fuels for India’s rail network. As part of the pilot, a single coach was retrofitted with 16 solar panels, each producing 300 watts in ideal sunny conditions, generating a cumulative power of 4.8 kilowatts for each coach. The generated power will be used to power lights and fans inside the coaches for use by the passengers. This single solar PV project will help Indian Railways reduce carbon dioxide emissions of 300 tonnes and save 95,000 litres of diesel per rake annually.
Solar potential for Railways
The project, once adopted on a large scale, is expected to open up the gates for adoption of solar energy by Indian Railways, which is one of the largest railways networks in the world. As per estimates, a train using solar power can reduce diesel consumption by up to 90,000 litres per year and also bring down carbon dioxide emissions by over 200 tonnes. The Indian Railways consists of more than 50,000 DEMU passenger coaches. If all these coaches convert to solar energy, it could prove to be a big success for the solar industry.
According to its Vision 2020 document, the Indian Railways plans to meet 10 per cent of its energy needs from solar and outlined plans to set up 1,000 mw of solar capacity in the country. The Railways is aiming to save Rs 41,000 crore in the next 10 years on energy bill by switching to alternate fuels such as solar.
India gets its largest vertical solar farm
- Jun 1, 2017
Tata Power Solar Ltd and Dell International Services India Pvt Ltd. have together built India’s largest vertical solar farm of 120 kW. The first of its kind, a 45m structure built on Dell’s Bengaluru campus provides the dual benefit of producing sustainable green energy and insulation of the building, thus helping reduce power consumption, a release from Tata Power Solar said.
The south-facing vertical solar farm was a very complex project as it needed to be integrated on the façade of the building without compromising on the aesthetics. The project is a foray for Tata Power Solar into vertical solar structures which have the potential to transform urban energy management, utilizing a fraction of the real estate which is at a premium in cities.
The solar farm, envisaged by Dell, produces enough energy to light-up its entire cafeteria and basement parking. While this significantly reduces the energy consumption of Dell, the panels itself act as solar insulation by blocking the south sun and thus reducing the power consumption of the air conditioning, the release noted.
Intricacies: The project, due to its unique design, needed significant innovation and customization of the structures, load bearing characteristics and anchorage. To integrate the 480 modules, manufactured by Tata Power Solar, a specially-designed, complex scaffolding was built. Safety was of utmost importance as the entire project was on a 11-storeyed building wall. For optimized plant performance, the vertical structure was designed with a 30 degree moving tilt to better enable maintenance.
Suzlon’s WTG achieves 42 pc PLF
- May 10, 2017
Suzlon Group has announced that its S111 120m 2.1 MW wind turbine generator has achieved around 42 per cent plant load factor (PLF) in its first 12 months of operation at the Jamanwada site in Kutch district of Gujarat.
The prototype was commissioned in March 2016. The 42 per cent PLF demonstrated by S111 120m is 20 per cent higher than 35 per cent PLF achieved by S97 120m in its first 12 months performance at the same location. The S111 wind turbine generator is the latest addition to the 2.1-mw platform and features the time-tested Doubly Fed Induction Generator (DFIG) technology. Read more
Gamesa commissions over 2 GW in FY17
- May 8, 2017
Gamesa India has announced that it has commissioned 2,050 mw of wind power during FY17 (April 2016 to March 2017), becoming the first ever wind company in India to have achieved this number in one year.
