| Contact Information & Safe Harbor Paul J. Bonavia, Chairman and CEO David G. Hutchens, President Kevin P. Larson, SVP and CFO Phil Dion, Vice President of Public Policy Investor Relations Contact Information Chris Norman, Manager Daniel Mark, Senior Analyst (520) 884.3649 (520) 884.3621 cnorman@uns.com dmark@uns.com Investor Information http://ir.uns.com Safe Harbor and Non-GAAP Measures This document contains forward-looking information that involves risks and uncertainties, that include, but are not limited to: state and federal regulatory and legislative decisions and actions; regional economic and market conditions which could affect customer growth and energy usage; weather variations affecting energy usage; the cost of debt and equity capital and access to capital markets; the performance of the stock market and changing interest rate environment, which affect the value of the company's pension and other postretirement benefit plan assets and the related contribution requirements and expense; unexpected increases in O&M expense; resolution of pending litigation matters; changes in accounting standards; changes in critical accounting estimates; the ongoing restructuring of the electric industry; changes to long-term contracts; the cost of fuel and power supplies; performance of TEP's generating plants; and other factors listed in UniSource Energy's Form 10-K and 10-Q filings with the Securities and Exchange Commission. The preceding factors may cause future results to differ materially from historical results or from outcomes currently expected by UniSource Energy. The Company's press releases and other communications may include certain non-Generally Accepted Accounting Principles (GAAP) financial measures. A "non-GAAP financial measure" is defined as a numerical measure of a company's financial performance, financial position or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP in the Company's financial statements. Non-GAAP financial measures utilized by the Company include presentations of revenues, operating expenses, operating income and earnings (loss) per share. The Company uses these non-GAAP measures to evaluate the operations of the Company. Certain non-GAAP financial measures utilized by the Company exclude: the impact of non-recurring items; the effect of accounting changes or adjustments; expenses that are reimbursed by third parties; and other items. The Company's management believes that these non-GAAP financial measures provide useful information to investors by removing the effect of variances in GAAP reported results of operations that are not indicative of fundamental changes in the earnings or cash flow capacity of the Company's operations. Management also believes that the presentation of the non-GAAP financial measures is largely consistent with its past practice, as well as industry practice in general, and will enable investors and analysts to compare current non-GAAP measures with non-GAAP measures with respect to prior periods. 1 |

| Energy Efficiency Standards ACC Energy Efficiency Standards Designed to require TEP and other affected utilities to implement cost effective demand side management programs Electric EE Standards target total retail kWh savings in 2012 of 3.0% of 2011 sales Targeted kWh savings increase annually in subsequent years until they reach a cumulative annual reduction in retail kWh sales of 22% by 2020 ACC Decoupling Policy Adopted in December 2010 Designed to encourage energy conservation by restructuring utility rates to separate the recovery of fixed costs from the level of energy consumed Policy indicates that revenue per customer decoupling may be well suited for Arizona as it responds to customer growth Utilities can propose decoupling mechanism in next general rate case application TEP Energy Efficiency Proposal TEP proposal and Staff recommendation filed with ACC 32 |

| 2008 TEP Rate Order - Key Provisions ACC Decision No. 70628 II. Rate increase 2.2 TEP's rates, including generation, will be determined using a cost-of-service methodology. ...TEP shall withdraw its proposed market and hybrid rate methodologies. Original cost rate base: $1.02B (net of $134M of adjustments, including deferred income taxes of $119M) Average base rate increase of 6% (avg. base retail rate of 8.9 cents/kWh) Includes base cost of fuel & purchased power of 2.8896 cents/kWh Revenue increase of $47.1M III. Ratemaking treatment of generation assets 3.1 For ratemaking purposes, SGS Unit 1 and Luna shall be included in TEP's rate base at their respective original costs. All other generation assets acquired by TEP after December 31, 2006, but before December 31, 2012, shall be included in TEP's rate base at their respective original costs, subject to the Commission's subsequent regulatory and ratemaking review and approval. 3.2 Recovery of SGS Unit 1 non-fuel costs shall reflect a cost of $25.67 per KW per month which approximates the levelized cost of SGS Unit 1 through the remainder of the primary lease term for this generating facility. In addition, SGS Unit 1 leasehold improvements shall be included in TEP's original cost rate base at net book value as of December 31, 2006. 3.3 Luna shall be included in TEP's original cost rate base at net book value as of December 31, 2006. 34 |

This provision is not intended to preclude TEP from seeing rate relief pursuant to this paragraph in the event of the imposition of a federal carbon tax or related federal cap and trade system. 35 |
| Reconciliation of Non-GAAP Measures 36 |
| Reconciliation of Non-GAAP Measures Base O&M 37 Base O&M, a non-GAAP financial measure, should not be considered as an alternative to Other O&M, which is determined in accordance with GAAP. We believe Base O&M provides useful information to investors because it represents the fundamental level of operating and maintenance expense related to our core utility business. Base O&M excludes expenses that are directly offset by revenues collected from customers and other third parties. 2011 2010 2009 -Millions of Dollars- -Millions of Dollars- -Millions of Dollars- TEP Base O&M (non-GAAP) $ 237 $ 228 $ 231 UNS Gas Base O&M (non-GAAP) 24 25 25 UNS Electric Base O&M (non-GAAP) 20 21 21 Consolidating Adjustments and Other (11) (9) (7) UniSource Energy Base O&M (non-GAAP) 270 265 270 Reimbursed Expenses Related to Springerville Units 3 & 4 63 65 41 Expenses Related to Customer-Funded Renewable Energy and Demand Side Management Programs 46 40 23 Total UniSource Energy O&M (GAAP) $ 379 $ 370 $ 334 |
| Reconciliation of Non-GAAP Measures TEP Retail Margin Revenues 38 Retail Margin Revenues, a non-GAAP financial measure, should not be considered as an alternative to Net Electric Retail Sales, which is determined in accordance with GAAP. Retail Margin Revenues excludes: (i) revenues collected from retail customers that are directly offset by expenses recorded in other line items; and (ii) revenues collected from third parties that are unrelated to kWh sales to retail customers. We believe the change in Retail Margin Revenues between periods provides useful information to investors because it demonstrates the underlying revenue trend and performance of our core utility business. Retail Margin Revenues represents the portion of retail operating revenues available to cover the operating expenses of our core utility business. 2011 2010 2009 -Millions of Dollars- -Millions of Dollars- -Millions of Dollars- Retail Margin Revenues: Residential $ 252 $252 $ 254 Commercial 160 159 160 Industrial 95 97 100 Mining 32 31 30 Public Authorities 12 12 12 Total Retail Margin Revenues (Non-GAAP)** $ 551 $551 $ 556 PPFAC Revenues 307 279 287 RES and DSM Revenues 46 38 25 Total Retail Revenues (GAAP) $ 904 $868 $ 868 |
| Reconciliation of Non-GAAP Measures TEP Long-Term Wholesale Margin Revenues 39 Long-Term Wholesale Margin Revenues, a non-GAAP financial measure, should not be considered as an alternative to Electric Wholesale Sales, which is determined in accordance with GAAP. We believe the change in Long-Term Wholesale Margin Revenues between periods provides useful information to investors because it demonstrates the underlying profitability of TEP's long-term wholesale sales contracts. Long-Term Wholesale Margin Revenues represents the portion of long-term wholesale revenues available to cover the operating expenses of our core utility business. 2011 2010 2009 Long-Term Wholesale Revenues: -Millions of Dollars- -Millions of Dollars- -Millions of Dollars- Long-Term Wholesale Margin Revenues (Non-GAAP)* $ 13 $ 28 $ 25 Fuel and Purchased Power Expense Allocated to Long- Term Wholesale Revenues 28 28 23 Total Long-Term Wholesale Revenues $ 41 $ 56 $ 48 Transmission Revenues 16 21 19 Short-Term Wholesale Revenues 73 64 86 Electric Wholesale Sales (GAAP) $130 $141 $153 |
