INTEGRATED RESOURCE PLAN (IRP)NOTICE OF FILING

ACIFICORP 2009 ELECTRIC INTEGRATED RESOURCE PLAN
YOU ARE HEREBY NOTIFIED that on May 29, 2009, PacifiCorp dba Rocky
Mountain Power (PacifiCorp; Company) filed its 2009 electric Integrated Resource Plan (IRP)
with the Idaho Public Utilities Commission (Commission). PacifiCorp is a multi-jurisdictional
utility and provides electric service to over 69 000 customers in eastern Idaho. The Company
filing is a biennial planning document that sets forth how the Company intends to meet the
energy requirements of its customers over the next 10 years.In Order No. 22299, the
Commission directed PacifiCorp to file a biennial IRP that analyzes its customer base, load
growth, supply-side resources, and demand-side management (DSM) resources. The Company
IRP was developed through a collaborative public process with involvement from regulatory
staff, advocacy groups and other interested parties and provides a framework of future actions to
ensure PacifiCorp continues to provide reliable service at a reasonable cost with manageable risk
to its customers.
The key elements of the PacifiCorp 2009 IRP include a finding of resource need
focusing on the 10-year period 2009-2018, a preferred portfolio of supply-side and demand-side
resources to meet this need, and an action plan that identifies the steps the Company will take
during the next 2 to 4 years to implement the plan. The resources identified in the 2009 IRP
preferred portfolio are considered proxy resources that guide procurement efforts, and do not
constitute the actual resources that would be acquired as part of future procurement initiatives.
Significant changes reflected in this IRP relative to the 2007 IRP include:
. A decrease in resource need: The system becomes short on capacity in
2011 rather than 2010 due to lower forecasted loads and new resource
additions.

NOTICE COMMENT DEADLINE
Acquisition of the 520 megawatt (MW) Chehalis gas plant and 175 MW
of additional wind resources added in 2008.
. New IRP guidelines issued by the Oregon Public Utility Commission on
the treatment of carbon dioxide (CO2) regulatory risk.
Incorporation of the Energy Gateway Transmission Project in the portfolio
analysis.
State commission 2007 IRP acknowledgement orders calling for modeling
methodology changes and the expansion of resource options to consider
including energy efficiency measures (Class 2 Demand-Side Management
programs) and additional renewable energy technologies such as solar and
geothermal.
THE INTEGRA TED RESOURCE PLANNING ENVIRONMENT
For capital expenditure planning, PacifiCorp states its challenge has been to
minimize customer rate impacts in light of a substantial capital spending requirement needed to
address customer load growth, support government environmental and energy policies, and
maintain transmission grid reliability. To address this challenge, the Company is scrutinizing
capital projects for cost reductions or deferrals that make economic sense in today s market
environment.
An additional planning challenge for the Company has been to respond to and predict
the demand response impacts of the economic recession and financial crisis. The Company
states that it is currently seeing a continuation of significant industrial and commercial sector
demand reduction. This will translate, it states, into a reduction of resource need for the near-
term.Volatile economic conditions and commodity prices are requiring the Company to
continuously re-evaluate input assumptions and resource acquisition strategies. Significant price
drops in fuels and forward wholesale power in late 2008 and early 2009 signal near-term
opportunities to lower power supply costs through market purchases before the Company needs
to commit to a large new thermal power plant. If construction markets continue to soften as
several experts predict, this will create additional cost-saving opportunities through lower plant
prIces.
The 2009 IRP also reflects evolution of PacifiCorp s corporate resource planning
approach. The Company has embarked on a strategy to more closely align IRP development
activities and the annual 10-year business planning process. The purpose of the alignment is to
NOTICE OF FILING
NOTICE COMMENT DEADLINE
adopt consistent planning assumptions, to ensure that business planning is informed by the IRP
portfolio analysis and that the IRP accounts for near-term resource affordability, and to improve
resource planning transparency for public stakeholders.
PacifiCorp s 2009 IRP accounts for the Energy Gateway Transmission project. For
the 2009 IRP cycle, the Company treated the various planned transmission segments as existing
resources for portfolio modeling purposes. Going forward, Gateway transmission segments will
be re-evaluated from an integrated resource planning perspective during the IRP and annual
business planning cycles.
RESOURCE NEEDS AND PORTFOLIO MODELING
The resource need accounts for load growth, sales obligations, existing resources
and a 12% planning reserve margin. Based on a November 2008 load forecast, PacifiCorp
experiences a capacity deficit beginning in 2011 , when the system will be short by 498 MW.
This deficit increases to 1 936 MW in 2012 and 3 528 MW by 2018. The capacity deficit is
driven by a coincident system peak load growth rate of 2.5% for 2009-2018, and expiration of
major power contracts such as the Bonneville Power Administration peaking contract in August
2011. On an energy basis, the system begins to experience summer short positions by 2012.
To determine how best to address the capacity deficits, PacifiCorp developed 57
resource portfolios using a capacity expansion model that optimizes resource choice according to
a variety of input assumptions and capacity planning criteria.PacifiCorp s state utility
commissions require the Company, through its IRP standards and guidelines, to develop a
portfolio that is least-cost after accounting for risk, uncertainty, and the long-run public interest.
2009 IRP PREFERRED PORTFOLIO
PacifiCorp s 2009 IRP preferred portfolio consists of a diverse mix of resources
dominated by renewable, demand-side management, gas-fired resources, and firm market
purchases. The major resources for the 2009-2018 planning period consist of the following:
Renewables:
- Wind: 1 313 MW
- Geothermal: 35 MW
- Major hydroelectric upgrades: 75 MW in 2012-2014
Demand-side management:
- Energy efficiency: 904 MW
- Dispatchable load control: 105-325 MW
NOTICE OF FILING
NOTICE COMMENT DEADLINE
. Gas-fired capacity: 831 MW in the 2014-2016 period
Coal plant turbine upgrades: 170 MW of emissions-free capacity
Firm market purchases: Ranging from 50 MW to 1 400 MW on an annual
basis, contingent on the time and amounts of long-term resource
acquisitions.
PacifiCorp is on pace to exceed the previous renewable resource amount identified in
the Company s 2007 Renewable Energy Action Plan filed in May 2007 (1,400 MW by 2015),
and the amount identified in the 2007 IRP update report filed in June 2008 (2 000 MW by 2013).
Since 2005 , the Company s projected renewable resource inventory has grown by 1,404 MW
accounting for existing resources and those under construction, contract, or included in the
capital budget. The incremental renewables identified in the 2009 IRP preferred portfolio and
action plan bring the target to about 2 040 MW by 2013. The projected renewable inventory
exceeds 2 540 MW by 2018, which represents 18.5% of PacifiCorp s owned generation
capability in that year.
2009 IRP ACTION PLAN
The 2009 IRP action plan is based upon the latest and most accurate information
available at the time of portfolio study completion. The current volatile economic and regulatory
environment will likely require near-term alteration to resource plans as a response to specific
events and improved clarity concerning the direction of the economy and government energy and
environmental policies.
PacifiCorp s 2009 IRP action plan consists of the following:
Renewables: 2009-2018
Acquire an incremental 1 400 MW of renewable by 2018 , in addition to
the already planned 75 MW of major hydroelectric upgrades in 2012-
2014; PacifiCorp s projected renewable resource inventory by 2018
exceeds 2 540 MW with these additions.
Firm Market Purchases: 2009-2013
Implement a bridging strategy to support acquisition deferral of long-term
intermediatelbase load resource(s) in the east control area until no sooner
than the beginning of summer 2014.
Peaking/Intermediate/Base Load Supply-Side Resources: 2012-2016
