HI SB3057

Changes the renewable portfolio standard calculation from percentage of electrical energy sales to percentage of electrical energy generation, excluding customer-sited grid-connected non-renewable generation.

Requires electric utility companies to annually track and report data and trends on customer retention and attrition to the Public Utilities Commission.

Maintains existing renewable portfolio standard targets (10% by 2010, 15% by 2015, 30% by 2020, 40% by 2030, 70% by 2040, 100% by 2045) but applies them to generation rather than sales.

Adds new category to force majeure exceptions allowing utilities to avoid penalties for inability to acquire sufficient cost-effective renewable energy and non-renewable energy from independent power producers outside utility control.

Takes effect July 1, 2050.
