NISE Calls Out Manufacturers for Mandatory Testing of CST Products

NISE has issued a letter calling out all industry stakeholders and manufactures CST products for the mandatory testing of all such products.

NISE CST Testing

The National Institute of Solar Energy (NISE), an autonomous institute under the Ministry of New and Renewable Energy (MNRE) has issued a letter calling out all industry stakeholders, state nodal agencies and domestic manufactures of Concentrated Solar Thermal (CST) products for the mandatory testing of all CST Products.

According to the letter issued by NISE, which along with Savitribhai Phule Pune University has been appointed as the testing facility for all CST products by the MNRE, has noticed that many manufacturers have made changes to their products without obtaining test reports for the improved systems first.

The institute has urged all concerned manufacturers, stakeholders, entrepreneurs, and developers to get their products tested and certified through NISE or through Savitribai Phule Pune University on or before December 31, 2019.

In case a company or related party fails to get their products tested, they would not be able to avail benefits under MNRE’s program for off-grid and decentralized CST technologies for community cooking, process heat, and space heating and cooling applications in industrial, institutional and commercial establishments.

Announced by the MNRE in 2014, this program aims to promote the use of CST technology for reducing dependence on fossil fuels for thermal applications like community cooking, process heating, cooling, and drying. Earlier this year, the program was further extended for the financial year 2019-20 to promote the application of solar thermal technology. 

Through the evaluation study, the MNRE is looking to analyse the effectiveness, impact, and necessity of this initiative. Moreover, the study is expected to help the ministry to decide on how to revise or renew the program.

The shrives that are available at the two testing facilities are:

  • Test facility for testing of hot water/steam-based CST systems
  • Test facility for testing of thermal oil-based CST systems
  • Mobile test facility for on-site performance evaluation of CST systems
  • Concentrated Solar Thermal (CST) component test facility
