Central Power Research Institute (CPRI) is a research institute originally established by the Government of India in 1960, with headquarters in Bangalore. The Institute was re-organized into an Autonomous Society in the year 1978 under the aegis of the Ministry of Power, Government of India. The main objective of setting up the Institute is to serve as a national Level laboratory for undertaking applied research in electrical power engineering besides functioning as an independent national testing and certification authority for electrical equipment and components to ensure reliability in power systems and to innovate and develop new products.

CPRI has been taking programs in various areas of electrical power generation, transmission and distribution in the endeavor to assist utilities to supply reliable, uninterrupted and quality services to the consumers. The broad objectives with the research projects are taken up in CPRI are

1. Offering technical advice and trouble shooting.
2. Product development and improvement to meet global standards.
3. Bridging the gap in testing and developing special testing technologies.
4. Large collaborative research projects with utilities and industries.
5. Electrical products and process improvement

While some of the programme are undertaken in collaboration with industries and utilities, other are taken up in-house to develop the expertise and infrastructure the power sector. The project proposals are planned well in advance keeping in mind the needs of the industry /utilities and are cleared by the committee on Research.

In CPRI, research and development projects of different dimensions are taken up under 4 schemes namely

1. IHRD (or In House Research and Development )
2. RSoP (Research Scheme on Power)
3. Sponsored projects
4. NPP (R&D under National Perspective Plan)

The performance of the institute in the field of testing and certification during the year 2009-2010 is very good as compared to 2008-2009. A total of 66347 tests on 22256 samples were conducted for 6127 organizations. The revenue realized from testing, certification and consultancy services rendered during this year increased to Rs.9600 lakhs as against Rs.7741 lakhs during 2008-2009.
