CPRI has expertise in the area of simulation, diagnostics, system analysis and testing. CPRI laboratories have medern equipment needed for power system simulation, short circuit testing, diagnostics of equipment, materials engineering, Seismic qualification etc. CPRI has experienced faculty in different subjects concerned to power sector with practical experience in their respective areas of interest, as well as extensive experience in presenting courses/seminars. The Institute organizes regularly Traning programs, Symposium, Workshops, Seminars/Conferences etc.

Capital Projects

CPRI has been allocated Rs. 320 Crore under XI plan Scheme by Ministry of Power aimed at supporting the projects related to establishing or upgrading test facilities and R & D projects under various schemes like Inhouse R & D, RSoP & NPP schemes. Out of this, 19 projects amounting to Rs 188.88 Cr is sanctioned so far and 4 projects are completed & others are in progress.

Research & Development

For the applied research specific to the power sector an autonomous body under the administrative control of the Ministry viz. Central Power Research Institute (CPRI) has been created and funds are being provided to them under Plan head to carry out the essential research schemes.

State of art Infrastructure facilities for undertaking collaborative research with academic institutions, utilities and industry has been established i.e. Center for Collaborative & Advanced Research (CCAR).

i) Plan R & D Projects

CPRI takes up In-house R&D projects aimed at product/process development, augmentation of test facilities, improvement of standards etc. in the areas of Generation, Transmission, Distribution & allied areas. Presently, 17 Research projects are under implementation in the Institute.

ii) Research Schemes on Power

Research Scheme on Power, a Research Fund of Ministry of Power sponsoring minor R&D programs is also being managed by the Institute. Under the scheme, various R&D projects from identified Research areas are provided with funds to Utilities and R&D organizations. The evaluation, monitoring & reviewing of the progress of these projects are prime responsibilities of CPRI in the management of the scheme. Currently, 13 projects are under implementation at various organizations.

iii) Research Project under National Perspective Plan

The National Perspective Plan report was brought out in the year 2001 by the Ministry of Power to identify major areas of research & development, funding requirement in the power sector up to 2012 and beyond. Subsequently, several research organizations were pooled together and many R&D projects were formulated & approved for implementation. Currently, 5 major projects are in various stages of progress at Bharat Heavy Electricals Ltd. (BHEL), Centre for Development of Advanced Computing (CDAC), EMCO, National Metturgical Laboratory (NML), Central Power Research Institute (CPRI) & Electrical Research & Development Association(ERDA). In the second phase, 6 projects with an outlay of Rs. 9.22 Crores have been approved and are under implementation at IIT-Roorkee, NHPC, CDAC with CIT & TNEB, Crompton & Greaves.
