Indian Railways turns to solar to cut coal-fired electricity costs FacebookTwitterLinkedInEmailPrint分享PV Magazine:To reduce its annual electricity bill, Indian Railways will soon run trains powered by solar power from arrays of PV cells deployed along electrified tracks in 10 states. The solar power generated will replace 4 GW of coal-fired electricity consumed by the railways, saving the operator 20% of its annual energy bill in the first year and 40% thereafter. Indian Railways currently buys electricity for around INR5 ($0.07) per unit.Developers will recover the installation cost of solar panels and other equipment through the sale of power to the railway operator. Under an agreement with states, there will be a provision to sell surplus power to the local utilities, which will supply equivalent power when Indian Railways needs it.The railway board is examining a project bid document prepared by the Solar Energy Corporation of India which recommends PV electricity from panels be fed through inverters and step-up transformers directly into the 25 kV overhead traction system. That would eliminate the cost of laying separate transmission lines and boost manufacturing of 25 kV single-phase inverters.Around 20 manufacturers, including ABB, Huawei, Delta and Sungrow, are said to be interested in manufacturing the equipment given sufficient demand, according to the Times of India. “This is a historic step towards Indian Railways becoming a net zero emitter by 2030,” railways and coal minister Piyush Goyal told the daily newspaper. “Indian Railways is by far the greenest travel option for transportation.”The government of India is encouraging cash-rich public sector undertakings to set up renewable energy projects. Indian Railways has committed to developing 5 GW of solar by 2025.More: Indian Railways plans to tender 4 GW solar project
Safeway, part of the Van Aalst Group of companies, has completed what it says is a first walk-to-work operation in Australian waters for client Woodside Energy.MMA Pinacle next to Pluto A; Source: SafewaySafeway said that the operation created hundreds of extra working hours for the Pluto Alpha offshore turnaround in the second quarter of 2019.The PLA gas production platform is operated by Woodside Energy and is located 190 km north-west of Karratha, Western Australia, in 85 meters of water. Gas from the Pluto field is piped through a trunk line to an onshore facility.For this project, Woodside Energy, MMA Offshore, and Safeway collaborated to install a 28-meter long walk-to-work Seagull-type on the 87,8 m long multi-purpose support vessel MMA Pinnacle.According to Woodside, the next stage following to project is to take lessons learned and use them in future scopes where W2W can add value, starting with the turnaround at North Rankin Complex in September.Also, Woodside has already started conversations for offshore turnarounds in 2020 and beyond.Wijnand van Aalst, CEO at Safeway, said: “Safeway is already operating with various striking types of motion compensated offshore access systems in areas such as the North Sea, Baltic Sea, and offshore Nigeria.“[…] we are grateful for this opportunity given by Woodside Energy and MMA Offshore to show the game-changing technologies of our Seagull-type W2W gangway in the Asia Pacific region as well.”Spotted a typo?
