Business Growth: Integrated Resource Plan Integrated Resource Planning Process  Under OPUC guidelines, PGE is required to file an Integrated Resource Plan within two years of acknowledgment of the previous plan  The IRP requires that the primary goal must be the selection of a portfolio of resources with the best combination of expected costs and associated risks and uncertainties for the utility and its customers  OPUC acknowledgement of the IRP is standard. Acknowledgement is not approval for rate-making purposes, but the Commission has stated that it will give “considerable weight” to utility actions that are consistent with the acknowledged IRP 2009 Integrated Resource Plan  In November 2010, PGE received acknowledgement of the IRP originally filed in November 2009  PGE filed a 2011 Integrated Resource Plan Update on November 23, 2011 – Includes an update to the 2009 Action Plan implementation activities – Examines new projections for future customer demand and the resulting portfolio balance – Addresses anticipated differences in timing for the acquisition of new resources identified in the 2009 Action Plan – Includes discussions on Demand Response, the Renewable Energy Standard, Boardman, Cascade Crossing and Wind Integration – Since PGE is not proposing changes to the IRP Action Plan, acknowledgement by the OPUC of the 2011 IRP Update is not necessary Next Integrated Resource Plan  The OPUC approved PGE’s plan to file an IRP update in November 2012 and a new IRP in November 2013 32

Recovery of Power Costs • Annual reset of rates based on forecast of net variable power costs (NVPC) for the coming year • Subject to OPUC prudency review and approval, new prices go into effect on or around January 1 of the following year • PGE absorbs 100% of the costs/benefits within the deadband, and amounts outside the deadband are shared 90% with customers and 10% with PGE • An annual earnings test is applied as part of the PCAM, using the regulated ROE as a threshold • Customer surcharge occurs to the extent it results in PGE’s actual regulated ROE being no greater than 9.0%; customer refund occurs to the extent it results in PGE’s actual regulated ROE being no less than 11.0% Power Cost Adjustment Mechanism (PCAM) Annual Power Cost Update Tariff 1) Per OPUC’s 2011 General Rate Case Order, deadband ranges are fixed and no longer represent 75 – 150 basis points of ROE 10.0% 9.0% 11.0% R e tu rn o n E quit y R e tu rn o n E quit y Baseline NVPC 90/10 Sharing ($15) million(1) $30 million(1) Customer Refund Customer Refund 90/10 Sharing Customer Surcharge Deadband Customer Surcharge Power Cost Sharing Earnings Test 39

Additional Renewable Resources Integrated Resource Plan addresses procurement of wind or other renewable resources to meet requirements of Oregon’s Renewable Energy Standard by 2015. Such need is now approximately 100 MWa (or 300 MW wind nameplate capacity) Year Renewable Target 2011 5% 2015 15% 2020 20% 2025 25% In 2011, Renewable Energy Standard qualifying renewables supplied approximately 10% of PGE’s retail load. In addition, PGE has several solar projects in place or in progress, for a total of approximately 8 MW Renewable Adjustment Clause (RAC) Renewable resources can be tracked into rates, through an automatic adjustment clause, without a general rate case. A filing must be made to the OPUC by the sooner of the on-line date or April 1st in order to be included in rates the following January 1st. Costs are deferred from the on-line date until inclusion in rates and are then recovered through an amortization methodology. Renewable Energy Standard 40

The decoupling mechanism is intended to allow recovery of margin lost due to a reduction in sales of electricity resulting from customers’ energy efficiency and conservation efforts Includes a Sales Normalization Adjustment mechanism (SNA) for residential and small non- residential customers (≤ 30 kW) and a Lost Revenue Recovery mechanism (LRR), for large non- residential customers (between 31 kW and 1 MWa) – The SNA is based on the difference between actual, weather-adjusted usage per customer and that projected in PGE’s 2011 general rate case. The SNA mechanism applies to approximately 58% of 2011 base revenues – The LRR is based on the difference between actual energy-efficiency savings (as reported by the ETO) and those incorporated in the applicable load forecast. The LRR mechanism applies to approximately 29% of 2011 base revenues OPUC order in PGE’s 2011 General Rate Case, authorized the continuation of the decoupling mechanism through December 31, 2013 For 2011, PGE recorded an estimated customer refund of approximately $1.5 million as weather adjusted use per customer was slightly more than levels included in the 2011 General Rate Case Decoupling Mechanism 41 (in millions) Q1 Q2 Q3 Q4 2011 Sales Normalization Adjustment $0.4 ($0.6) $1.0 ($1.4) ($0.6) Loss Revenue Adjustment $0.1 ($0.6) ($0.2) ($0.2) ($0.9) Total adjustment $0.5 ($1.2) $0.8 ($1.6) ($1.5) Note: refund/surcharge = (negative)/positive

Boardman 2020 Emissions Controls Emissions Controls at the Boardman Plant  In December 2010, the Oregon Environmental Quality Commission (OEQC) approved revised Best Available Retrofit Technology (BART) rules  June 2011, EPA approved revised rules, which were published in the Federal Register in July 2011  To comply with the revised rules, PGE plans to: – Use lower sulfur coal to fire the plant’s boiler – Install low NOx burners and modified over-fired air ducts – Install dry sorbent injection systems (DSI) to address SO2 and mercury • Contingent upon successful pilot testing: − PGE would meet a 0.4 lb SO2/MMBtu limit using DSI by July 2014 − PGE would meet a 0.3 lb SO2/MMBtu limit using DSI by July 2018 – Cease coal-fired operations no later than December 31, 2020  PGE Share of 2011 capital spending on Boardman controls was approximately $17 million – Installed low NOx burners and over-fire air ducts – Mercury controls installed and performance testing is complete  Remaining PGE capital cost estimated at $22 million in 2011 and 2012  In December 2011, EPA released its final utility MACT rule; based on our preliminary full-scale testing results, Boardman should be able to meet MACT requirements once currently planned controls are in place 43
