City Council Expands Solar Limits

Residents in Pasadena can now install larger solar systems thanks to a resolution passed by the City Council on Monday.

The resolution is part of the city’s strategy to reach 100% carbon-free electricity by 2030.

Under the proposal, Pasadena Water and Power now permits customer-owned solar systems sized up to 150% of a household or business’s maximum annual electricity use over the past five years.

Installations greater than 150% are allowed if paired with energy storage, capped at one megawatt, and subject to grid capacity reviews.

“Local solar and storage are essential to Pasadena’s carbon-free future. We want our community to be partners in this effort by installing solar and preparing for an electrified tomorrow,” said Councilmember Justin Jones, who chairs the City Council’s Municipal Services Committee, which recommended the item to the City Council.

According to city staff, the changes are meant to align local policies with state law and Pasadena’s electrification targets, which anticipate higher energy demand as more residents transition to electric vehicles and appliances.

Previously, the city limited solar system sizing to 100% of annual usage.

The measure is part of a broader clean energy strategy that includes rate modernization, customer generation, and utility-scale procurement.

More than 30 megawatts of solar and storage capacity have been installed in Pasadena to date, mostly by residential customers.

Officials point out that any system expansion must ensure the safety and reliability of the distribution grid. A concurrent study is assessing impacts of customer-sited generation on transformers, feeders, and substations.

The resolution also directs Pasadena Water and Power staff to develop recommendations for incentives, such as a battery rebate program, to encourage storage that can ease strain on the grid and provide backup power.
