SWEPCO IRP Process
The IRP Process requires the selection of a mix of resources to meet SWEPCO’s future energy and
capacity needs. Resources are generally categorized into traditional supply side, demand side and
variable (or intermittent) energy resources.
 Supply Side Resources
 Baseload
 Intermediate
 Peaking
 Demand Side Resources
 Energy Efficiency
 Demand Response
 Customer-Owned Generation
 VVO/Smart Grid
 Variable (Intermittent) Energy Sources
 Solar
 Wind

Objectives for the SWEPCO IRP Stakeholder Process
Stakeholder input is an important part of the IRP process. SWEPCO identified three main objectives for
stakeholder engagement:
 Inform: Increase stakeholders’ understanding of the IRP process, key assumptions used in the IRP, and
challenges that SWEPCO faces.
 Listen: Understand our stakeholders’ resource planning concerns and objectives.
 Consider: Provide a forum for productive stakeholder feedback on specific topics at key points in the IRP
process to inform SWEPCO’s decision-making.
Two stakeholder workshops will be held during the planning process. The tentative timeline is shown below.

The Integrated Resource Planning Process
 Resource planning is a complex effort that must
balance the needs of a variety of constituents:
 Customers
 Regulators,
 Shareholders, and
 Other Stakeholders…
There are many priorities that compete for resources as SWEPCO works
toward its objective to provide safe, reliable, clean power at rates that are
reasonable.
 …while ensuring that electricity is provided in a safe,
reliable, and efficient manner at reasonable rates.
 The process involves looking at “big-picture” trends
that affect energy markets, developing and using
forecasting and analysis models, and selecting
approaches that will meet customer needs in the
safest, most reliable and economical way given the
uncertainties about the future.

The Integrated Resource Plan Development - Study Description
Creating an Integrated Resource Plan (IRP) involves four basic and interconnected steps:
 Step 1: Gathering data, developing input assumptions and creating scenarios
 Step 2: Portfolio Development
 Step 3: Analyzing portfolios
 Step 4: IRP Report Development
Develop a forecast of customer demand
Evaluate on-going capabilities of existing resources
to meet that demand
Determine the need to be
filled – amount, timing and type
Identify (supply and demand side) resources
that may be available to meet the need
Use sophisticated modeling techniques
to provide insight to the best solution
Produce the integrated resource plan
8
Step 1: Gathering data, developing input assumptions and creating scenarios
This phase of the IRP development involves:

SWEPCO works with its internal experts to develop forecasts for commodities and fuel prices. These
are the core drivers in the integrated resource plan.

SWEPCO meets with interested stakeholders to solicit feedback on IRP input assumptions.

Load forecasts are developed for the next twenty years and beyond. These forecasts take into
consideration elements such as projected economic growth and energy efficiency effectiveness. They
help the resource planners to anticipate the level of energy and capacity needed during the 20-year
timeframe (2015-2034) of the IRP.

Cost projections are developed for new construction, environmental compliance, and other key input
assumptions.

Potential resource options are screened to eliminate those that have technical and commercial
availability limitations or are not feasible in SWEPCO’s service territory.

Assumptions on operational characteristics of existing resources are revisited, including their anticipated
remaining useful life.

Scenarios are developed to reflect possible futures. These scenarios will be used to guide analysis of
different resource portfolios.
9
Step 1 (cont’d) - Scenario Development, Cost and Performance Assumptions
IRP development involves the creation of a comprehensive set of economic
.scenarios to fully evaluate potential resource portfolios.
 SWEPCO has developed five economic scenarios which cover a wide range of possible future states.
 Base Commodity Pricing (with CO2 emissions at $15/metric-ton beginning in 2022)
 Lower Band Commodity Pricing
 Higher Band Commodity Pricing
 No Carbon (assumes cost of CO2 emissions is $0/metric-ton)
 High Carbon (assumes cost of CO2 emissions is $25/metric-ton)
 Economic Scenarios are fully integrated, sensitivities change a single variable
 Scenarios encapsulate
future states in a way that
all input variables are
simultaneously plausible.
Examples include
o“low growth” or
o“boom economy”
 Sensitivities change a single
variable so that its impact
within a scenario can be
understood.
 Examples include:
o carbon tax,
o high gas prices,
o low gas prices
 Sensitivities are not the
basis for portfolio
construction.
10
Step 1 (cont’d) - Scenario Development, Cost and Performance Assumptions
. Cost
and Performance Assumptions are derived from publicly available data
where feasible
 Supply-side asset costs are derived from government sources
 Performance factors will reflect costs and geography of SWEPCO service territory
 Develop assumptions regarding cost effective demand side programs such as program cost
and program life.
 Develop assumptions regarding the adoption of customer owned generation and amount
and timing of its deployment.
11
Step 2: Portfolio Development
This phase of the IRP development involves:
 For each of the economic scenarios, SWEPCO will create a cost-optimized portfolio
using the Plexos modeling software
 Plexos is a model that incorporates all of the fundamental inputs and supply and
demand options.
 Plexos can:
 Given a set of fundamentals, “build” a portfolio that has the lowest (PV) revenue
requirements
 Given a supply and demand side portfolio, determine its (PV) revenue requirements
 Given both, run multiple (Monte Carlo) iterations
 Portfolios will be subject to robust analyses (see next slide)
 The results of these analyses will guide SWEPCO in the selection or creation of a
preferred portfolio
12
Step 3: Analyzing Portfolios
This phase of the IRP development involves:
 Each model-optimized portfolio is evaluated in more detail.
 Each of the five portfolios is evaluated under all pricing scenarios.
 In addition to the discrete modeling in the previous step, an evaluation which measures the
“revenue requirement at risk” of each portfolio is also performed (see next slide).
 The preferred resource portfolio is selected by determining which portfolio best meets a
number of quantitative and qualitative criteria. Portfolio costs under each scenario, results
of sensitivities, risk analysis and other key considerations including system diversity and
environmental footprint are used in this selection process.
 The preferred resource portfolio may be a hybrid portfolio which includes options from each
of the optimized portfolios.
13
Step 3: Analyzing Portfolios - Risk Modeling
“Risk” is the likelihood and magnitude of a bad outcome.
The present value of revenue requirements is measured
over 100+ simulations that vary key inputs
 Power, CO2, natural gas, coal
“Revenue Requirements at Risk” is defined as the difference in the 95% of results from the 50% (median) results.
14
Step 4: IRP Report Development
This phase of the IRP development involves:
 Results of the preferred resource portfolio and other key components of the draft IRP will
be shared with stakeholders prior to finalizing the IRP.
 After receiving stakeholder feedback, the final document is prepared and reviewed to
assure all regulatory requirements are met.
 The report is then presented to SWEPCO senior management prior to final submittal to the
Louisiana Public Service Commission in August 2015.

Note: Effective 2015, SWEPCO wholesale customer NTEC to migrate from a "gross" 'full-requirements' (~720 MW) wholesale load to a simple, 'fixed' 200 MW
requirement load. Simultaneously, the contract will also lead to the removal from SWEPCO's resource portfolio of approx. 500 MW of self supplied capability for
which SWEPCO had been obligated to dispatch in SPP and utilize within its long-term planning

Planning assumptions for SWEPCO’s IRP development
Publicly available data from
the US Energy Information
Administration will be the
starting point for
SWEPCO’s resource cost
assumptions
23
Planning assumptions for SWEPCO’s IRP development
Intermittent resource costs are expected to decline. For wind projects, the Production Tax
Credit (PTC) is assumed not to be in effect (it expired at the end of 2013). Solar Investment
Tax Credit of 30% applies until 2016 and is reduced to 10% in 2017 and beyond.
24
Planning assumptions for SWEPCO’s IRP development
Efficiency Resource costs are expected to continue to increase.
Residential and Commercial consumption is flat-to-declining and EISA
lighting standards are fully phased-in.
25
