Electricity Distribution Utility preparedness for electric vehicles

The simplest way to look at electrification of transportation is that it eventually leads to an increase in electricity demand. Every electric vehicle (EV) is effectively a new consumer for the electricity distribution company (DISCOM).

When it comes to electricity connection for EV charging facilities, one of the key questions that needs to be answered is ‘who will bear the cost of the grid upgradation?’. Will the DISCOM bear the cost of upgradation? Should the charging service provider or the consumer bear the cost? As I see it, there are some unavoidable costs associated with the procurement ‘wires and poles’ to get the connection. But then again, I believe it is possible to limit the expenditure on the grid upgradation.

‘who will bear the cost of the grid upgradation?’.

One of the numerous 'chicken and egg' questions that have plagued the advent of the EV industry-- thanks for the in depth dive into this topic. If you had to grade the job DISCOMs are doing today at EV preparations, what would you give them?

Hi Matt, I would want DISCOMs to actively partner in the process of ev charging. We are seeing globally that consortia where ev manufacturers or battery  manufacturers with utility partners will work for establishing charging facilities.

Secondly, they have to be smart. DISCOMs know in and out of their network, and loads. Data is a good tool solve the charging problems. DISCOMs need to gather and analyse data on how, when and where vehicles are charging. With the data they can take good control measures.

Hi , therefore DISCOs cannot go alone . It must there be cooperation between service provider (Disco) and beneficiaries ( EV owners). If owner is  going to installe inhouse charger, he has to get permission from Disco  . Also, as one intends to installe a common chargers station he has to get permission . By this Disco can mannage the network loading and avoid  tchenical arising problem of overloading transformers or sutransmission lines.
