The AMI policy incorporates guidelines for data protection and mandates compliance with the Information Technology Act, 2000, and related data protection regulations.

In 2017, The Supreme Court of India held that Right to Privacy stemmed from the fundamental right to Life. Protection of consumer data is integral to the deployment of smart meters and smart grids. In the highly competitive Energy markets, there is a raised possibility of cyber attacks and there must be integrated protocols with Smart Grids to prevent breach of data confidentiality.

Consumer data, if breached, can be misused for unlawful and illegal purposes such as burglars analyzing the daily patterns of individuals and families to ascertain when homes are unoccupied. Further if this data is sold to third parties, it can be used in targeted advertising. Data can be used by various companies to leverage a competitive advantage by analyzing consumer patterns and is considered an important aspect of competition law.

However, balance must be struck between efficiency and consumer data protection which can be done by introducing specific parameters for data protection and increasing competition in the market. Interoperability- the transfer of useful data across systems and sharing of this data with competitors by increasing interconnectivity of various platforms- may be the solution to controlling dominance, this results in competition in the energy sector, perhaps loosening dominant enterprises.

The smart meter business is dominated by a few private entities in India and the interoperability would allow for consumer empowerment, allowing them to switch services if unsatisfied. The right to switch smart meter suppliers strengthens the consumers right to "opt-out". The lack of interoperability relegates the customers "choice" to a single distribution company.

Under the Model Smart Grid Regulations, the Forum of Regulators directed that agencies responsible for smart grid projects should ensure that protection of consumer data and consumer privacy is accorded highest levels of priority.

Example:

Utilities in Karnataka have implemented robust encryption and data protection measures to ensure compliance with data privacy laws and build consumer trust.
