The TEP budgets also include the recovery of approximately $ 3.4 million in under-income from a two-year renewable energy program funding award and $ 2 million over three years to fund a pilot program that will provide incentives for customers who install their own battery storage systems.
TEP has not yet finalized the details of its home energy storage pilot project, but plans to roll out the program sometime this fall, company spokesman Joe Barrios said.
A similar pilot was approved last year for Arizona Public Service Co., which offers incentives of up to $ 2,500 for customers who install battery systems in their homes to store grid electricity or rooftop solar panels.
Home battery systems currently cost about $ 7,000 to $ 15,000, depending on capacity, excluding federal tax credits for storage systems attached to solar panels.
The Corporations Commission also approved UniSource’s renewable energy plans, with a budget of about $ 9.6 million for 2021, when it will also raise about $ 484,000 to cover a previous recovery shortage and a budget of about $ 9 for 2022 , $ 1 million.
But the Corporation Commission turned down a UniSource proposed pilot program of energy storage for residential buildings and was reluctant to face the proposed two-year cost of about $ 300,000.
Both UniSource and TEP submitted their energy storage proposals at the request of Commission staff last year as part of discussions on government rules for renewable energy and energy efficiency.
