Vulnerable ACT customers should no longer foot the bill for "inequitable" solar power schemes that are overly generous towards better-off households, the competition watchdog has found.

ACT Sustainability Minister Shane Rattenbury said he would consider the commission’s recommendations with regards to the ACT’s feed-in scheme for solar power, lauded as one of the most generous in the country when introduced in 2009.

"The recommendation on feed-in tariffs essentially asks all taxpayers to share the cost of supporting small-scale clean energy generation, instead of all electricity users," Mr Rattenbury said.

"As we consider this recommendation and the others in the ACCC's report, we'll be assessing their sutiability to the ACT contaxt, with particular regard to how they might affect vulnerable energy users and low-income households."
