A presentation by Hogan Lovells privacy partners compares European Commission “EG2” privacy recommendations for smart grids with the comparable recommendations of the NIST. We explain the concept of “privacy by design” in the smart grid environment and the use of detailed privacy use cases to mitigate system risks. The presentation compares the U.S. concept of “PII” with the European concept of “personal data” and discusses the risks associated with transferring household electricity data to third parties, as is mandated by California and Italian law.
