Direct Normal Irradiance (DNI) data at close intervals of time are essential for the assessment of the energy generated by Concentrated Solar Power (CSP) plants. To accurately predict the output of CSP plants taking into account cloud cover, data at few-minute intervals are required. There was a long felt need for DNI data in India. The report contains DNI data for 22 stations, an attempt to meet this need. The data presented in this report may be useful in carrying out techno-economic assessment of future CSP plants in these locations.
