Tucson Electric Power Proposed New Solar Program

LCG, September 25, 2009--Tucson Electric Power (TEP) yesterday announced a new solar program that would allow its customers to purchase 150 kWh "blocks" of solar energy generated by a local photovoltaic (PV) arrays. TEP anticipates selling solar blocks in mid-2010, given timely approval of the proposed Bright Tucson Community Solar Program by the Arizona Corporation Commission (ACC).

According to TEP, by adding as little as $3 per month to their electric bills, customers could purchase solar energy to offset their carbon footprint and use of fossil-fueled power. Approximately six blocks of solar energy would meet the annual electric use of a typical residence, which would add $18 per month to a customer's bill. Customers would not be required to make a long-term commitment and could add or subtract blocks at any time.

TEP also states that the Bright Tucson Community Solar Program will allow customers to lock in a fixed energy rate for up to 10 years. Furthermore, for those solar blocks, participants would not pay charges linked to fossil-fueled energy sources, including TEP's base energy charge and the Purchased Power and Fuel Adjustment Charge (PPFAC).

A TEP spokesperson stated, "We're looking to locate these systems in areas of our local distribution grid where we'll realize the most benefit from additional generating resources."

TEP's first solar PV system to power the program is a 1.6-MW facility scheduled for construction in 2010 as part of the Bright Tucson project, a demonstration project designed to make solar energy more effective through the use of energy storage systems and a demand response program. TEP has requested $25 million in funding from the U.S. Department of Energy (DOE) for the project.

The Bright Tucson Community Solar Program would be funded in part by an ACC-approved surcharge intended to support the Arizona?s Renewable Energy Standard (RES), which requires utilities to increase their use of renewable energy, with a renewable energy target of 15 percent by 2025.
