Researchers and ECC Engineers from Citizen consumer and civic Action Group (CAG) attended a three-day training programme at Auroville Consulting (AVC) from 16 December 2019 to 18 December 2019. The programme focused on several topics ranging from TN Solar Policy 2019 and rooftop solar installation to e-mobility and smart grid systems. The sessions of the programme were designed and structured in such a way that each of them were supplemented with site visits and expert interactions.

Highlights of the training programme: 

  1. The sessions enabled a hands-on learning experience with site visits to Auroville’s rooftop solar installation, wastewater treatment plant and e-cycles initiative.

  2. The programme provided ample scope to explore the various energy efficient and sustainable practices followed at Auroville.

  3. The sessions were complimented with interactions, discussions and board games that enhanced the learning experience.

  4. The sessions were delivered by experts who presented the topics based on their respective  experience and aurovillian experiments.

Mr.  Toine van Megen delivered the first session of the programme. He presented a detailed analysis of the Tamil Nadu Solar Policy 2019. Following which Mr. Shiv Vembadi presented on the implementation of KUSUM in Tamil Nadu. He explained that an integrated approach ie., combing energy-efficient pumps and advanced irrigation methods will conserve energy as well as water.  

The afternoon session on rooftop solar installation was conducted by Mr. Debabrata Sahoo.
