NTPC Ltd.

NTPC is planning to invest Rs 1,000 crore on research and development (R&D) exercise in six years that will involve groundbreaking work in areas of new and renewable energy, waste management, efficiency improvement and cost reduction. Last year NTPC spent about Rs 129 crore or nearly 1.2% of its profit after tax on R&D.

The company, which recently announced big plans for entering the solar energy sector, has decided to work on developing power generation technologies that will use lesser volumes of coal and thus reduce greenhouse gas emissions.

NTPC is the largest power generating company in the country. It has also diversified into hydro power, coal mining, power equipment manufacturing, oil & gas exploration, power trading & distribution.
