Railways form the backbone of the Indian Transportation System. The Railways has undertaken following measures under its Go Green initiatives:
- Ministry of Railways has planned to set up 1000 Mega Watt (MW) solar power by 2020-21. This would help Railways to source about 10% of its electrical energy from renewable source.
- Wind energy plants of 36.5 MW have been installed by the Railways.
- Almost all electrified Railway stations and 99% of service buildings have been fitted with 100% LED luminaries by Indian Railways to reduce power consumption.
- Railways have started blending of 5% bio-diesel in High-Speed Diesel (HSD) for diesel locomotives.
- 20% Compressed Natural Gas (CNG) substitution in diesel engines of Diesel Power Cars of Diesel Electric Multiple Unit (DEMU) trains and the introduction of solar energy based DEMUs.
- Tree plantation to increase green cover in Railway Premises.
- Water Audits at major consumption centres as well as the proliferation of Water Recycling Plants and Rain Water Harvesting (RWH) Systems as a step towards better water management.
- Assessment and rating of Indian Railway’s Production Units and major Workshops as Green Industrial Units.
- Nearly 163,000 bio-toilets have been installed in around 44,500 coaches.
- Increasing the pace of electrification to reduce the dependency on fossil fuels.
Also, the Ministry of Railways has taken a policy decision for allocating 1% cost in all sanctioned works for execution of environment-related works.
Union Ministry of New and Renewable Energy (MNRE) has prepared draft of Indian Wind Turbine Certification Scheme (IWTCS) incorporating various guidelines of Turbine Certification Scheme. It has been prepared in consultation with Chennai based National Institute of Wind Energy.
Indian Wind Turbine Certification Scheme (IWTCS)
- It is consolidation of all relevant national and international standards, technical regulations and requirements issued by Central Electricity Authority (CEA), guidelines issued by MNRE and other international guidelines.
- It enlists guidelines for benefit of all stakeholders from concept to lifetime of a wind turbine, including Indian Type Approved Model (ITAM), Indian Type Certification Scheme (ITCS), Wind Farm Project Certification Scheme (WFPCS) and Wind Turbine Safety & Performance Certification Scheme (WTSPCS).
- It incorporates the best practices from other nations in order to ensure the quality of the wind energy projects.
IWTCS aims to assist and facilitate following stakeholders
- Original Equipment Manufacturers (OEMs)
- End Users –Utilities, Developers, IPPs, Owners, Authorities, Investors and Insurers
- Certification Bodies.
- Testing Laboratories.
- Wind energy has over period become mainstream source of renewable power generation in India. The steady growth of the sector has seen different types of wind turbines with diverse performance and safety criteria.
- MNRE through various policies and schemes has facilitated the healthy and orderly growth of this sector.
- The modern wind turbines have higher hub heights, larger rotor diameter, higher capacity and improved Capacity Utilization Factor (CUF) along with technological improvements.
- Under these developments, there is need for comprehensive scheme that provides complete technical requirements that have to be complied by wind turbines for safe and reliable operation by all the stakeholders.
- Also, there is need for technical regulations that shall facilitate common ground for OEMs, Developers, Investors and Financial Institution for systematic development.
