H.B. 1520 Summary

• Requires electric and gas utilities to maintain and provide energy consumption data for nonresidential buildings after December 31, 2020, using a portfolio management tool compatible with EPA's ENERGY STAR Portfolio Manager.

• Mandates nonresidential building owners or operators disclose benchmarking data to prospective buyers, lessees, or lenders for the most recent twelve-month period, with phased implementation based on building size (over 50,000 sq ft by January 1, 2022; over 10,000 sq ft by January 1, 2023).

• Allows utilities to provide aggregated energy data that complies with the "rule of 15/15" (anonymization standard requiring at least fifteen data members with no single member exceeding fifteen percent of measured quantity) or account-specific data with customer authorization.

• Establishes that building owners or operators providing benchmarking data to prospective parties are not required to provide additional energy consumption information, and such disclosure is deemed adequate.

• Effective date: July 1, 2100 (appears to be a clerical error given the bill's context).
