The National Energy Modeling System
Integrating Module of the National Energy Modeling
System (INT)
Description
The National Energy Modeling System (NEMS) is an energy-economy modeling
system of U.S. energy markets used for mid-term projections through 2030,
as well as for energy and environmental policy analysis. NEMS projects
the production, imports, conversion, consumption, and prices of energy,
subject to macroeconomic and financial factors, world energy markets,
resource availability and costs, behavioral and technological choice criteria,
cost and performance characteristics of energy technologies, and demographics.
The model reflects market economics, industry structure, and energy policies
and regulations that influence market behavior.
The integrating module of the National Energy Modeling System controls
the solution algorithm, manages the global data, and implements greenhouse
gas emissions accounting and associated policy options.
This section addresses some aspects of NEMS common to all of the component
modules, including computing and archive information.

Documentation
Archive Media and Installation Manual(s)
NEMS has been archived for the reference case published in the Annual
Energy Outlook 2006, DOE/EIA-0581 (2006). The NEMS archive contains all
of the nonproprietary modules of NEMS as used in the reference case.
The NEMS archive is available on an as-is basis (ftp://eia.doe.gov/pub/oiaf/aeo/aeo2006.zip).
The purpose of the archive is to disclose the source code and inputs used,
as well as to demonstrate that the published results from the AEO reference
case can be reproduced by re-running the model. The archive does not include
the executable model, although it can be generated from the source code
of the model with the appropriate software, some of which is proprietary.
While there is no Installation Manual, brief instructions for compiling
the source code, setting up a run, and replicating
the AEO reference case are included in a file named readme.txt
that is included with the archive.
Coverage
- Geographic: Nine Bureau of Census Divisions. Some component
analytical modules represent energy production or conversion at different
levels of regional detail
- Time Unit/Frequency: Annual through 2030
- Product(s): Natural gas, electricity, coal, steam coal, metallurgical
coal, distillate fuel oil, residual fuel oil, motor gasoline, jet fuel,
liquefied petroleum gases, petrochemical feedstocks, kerosene, other
petroleum products, methanol, ethanol, nuclear power, hydropower, and
other renewable sources
- Economic Sector(s): Residential, commercial, industrial, and
transportation end-use consumption; coal supply; oil and gas production

Modeling Features
- Model Structure: NEMS is structured as a set of quasi-independent
modules, executed iteratively in a convergence algorithm designed to
simulate annual energy market equilibria over the projection horizon.
- Modeling Technique: NEMS is a simulation of the impacts of
present and planned energy market conditions and regulations on the
supplies of and demands for energy products. Different techniques are
applied in different sectors, as appropriate.
- Special Features: The primary design feature of NEMS is its
modularity. That is, the model is organized by fuel production
oil, natural gas, coal, and electricity and by end-use consumption
sector. The modularity allows any single module or group of modules
to be run independently as a debugging aid or for stand-alone analysis.
Furthermore, modularity also allows the flexibility for each sector
to be represented in the most appropriate way, highlighting the particular
issues important for the sector, including the most appropriate regional
structure.

Computing Environment
- Hardware Used: Personal computer workstations
- Operating System: Windows XP
- Language/Software Used:
The parts of NEMS using OML are the Electricity Market Module, the
Coal Market Module, the Petroleum Market Module, and the Natural Gas
Transmission and Distribution Module. While the OML libraries are
in the archive, the OML software will not run unless the user licenses
the OML software with KMS Optimization Products and obtains a key.

Coal Market Module (CMM)
Description
The Coal Market Module (CMM) is one of the four energy supply modules
included in the NEMS modeling framework. The CMM simulates mining, transportation,
and pricing of coal, subject to the end-use demand for coal differentiated
by heat and sulfur content. U.S. coal production is represented in the
CMM using 40 separate supply curves differentiated by region, mine
type, coal rank, and sulfur content. Projections of U.S. coal distribution
are determined in the CMM through the use of a linear programming algorithm
that determines the least-cost supplies of coal for a given set of coal
demands by demand region and sector, accounting for minemouth prices,
transportation costs, existing coal supply contracts, and sulfur and mercury
allowance costs. Over the forecast horizon, coal transportation costs
in the CMM are projected to vary in response to changes in railroad productivity
and the user cost of rail transportation equipment. The CMM produces projections
of U.S. steam and metallurgical coal exports and imports, in the context
of world coal trade. The CMMs linear programming algorithm determines
the pattern of world coal trade flows that minimizes the production and
transportation costs of meeting a set of regional world coal import demands,
subject to constraints on export capacities and trade flows.
The CMM consists of two submodules: Coal Production Submodule (CPS),
and Coal Distribution Submodule (CDS). The CDS consists of two components:
a domestic component representing the U.S. coal market, and an international
component representing world coal trade.
The Coal Production Submodule (CPS) The CPS produces
supply-price relationships for 14 coal producing regions, nine coal types
(unique combinations of thermal grade and sulfur content) and two mine
types (underground and surface) addressing the relationship between the
minemouth price of coal and corresponding levels of capacity utilization
at coal mines, annual productive capacity, labor productivity, and the
cost of factor inputs (mine labor, mining equipment, and fuel). The CPS
generates regional, mid-term (to 2030) coal supply curves for input to
the National Energy Modeling Systems (NEMSs) Coal Distribution,
Electricity Capacity Planning (ECP) and Electricity Fuel Dispatch (EFD)
Submodules.
Coal Distribution Submodule (CDS), Domestic Component
The domestic component of the Coal Distribution Submodule (CDS)
forecasts coal distribution from 14 U.S. coal supply regions to 14 domestic
demand regions. The model consists of a linear program with constraints
representing environmental, technical and service/reliability constraints
on delivered coal price minimization by consumers. Coal supply curves
are input from the CPS, while coal demands are received from the Residential,
Commercial, Industrial and Electric Power components of NEMS, with export
and import demands being provided by the international component of the
CDS.
Coal Distribution Submodule (CDS), International Component
The international component of the CDS projects coal trade flows
from 16 coal-exporting regions (five of which are in the United States)
to 20 demand or importing regions (four of which are in the United States)
for three coal types premium bituminous, low-sulfur bituminous,
and subbituminous. The model consists of supply, demand, trade and transportation
components. The major coal exporting countries represented include: United
States, Australia, South Africa, Canada, Indonesia, China, Colombia, Venezuela,
Poland, and the countries of the Former Soviet Union. The model is used
to forecast international coal trade. It provides projections of U.S.
coal exports and imports to the domestic component of the Coal Distribution
Submodule.

Modeling Features
Coal Production Submodule (CPS)
- Model Structure: The CPS employs a regression model to estimate
pricesupply relationships for underground and surface coal mines
by region and coal type, using projected levels of capacity utilization
at coal mines, annual productive capacity, productivity, miner wages,
capital costs of mining equipment, and fuel prices.
- Modeling Technique: Three main steps are involved in the construction
of the coal supply curves:
- Calibrate the regression model to base-year production and price
levels by region, mine type (underground and surface), and coal
type
- Convert the regression equation into supply curves
- Construct stepfunction supply curves for input to the CDS,
ECP, and EFD
Coal Distribution Submodule (CDS), Domestic Component
- Model Structure:The CDS uses 40 coal supply sources representing
12 types of coal produced in 14 supply regions. In the CDS, coal types
are defined as unique combinations of thermal grade, sulfur content
and mine type. The definition of coal types in the CDS differs slightly
from the NEMS CPS, where coal types are defined as unique combinations
of thermal grade and sulfur content. Coal shipments to consumers are
represented by transportation rates specific to NEMS sector and supply
curve/demand region pair, based on historical differences between minemouth
and delivered prices for such coal movements. In principle there are
27,440 such rates for any forecast year; in practice there are less
since many rates are economically infeasible and a unique transportation
rate is not derived for each of the 35 electricity sectors. Coal supplies
are delivered to up to 49 demand subsectors in each of the 14 demand
regions. Currently the NEMS system provides projections of U.S. coal
demand through 2030.
- Modeling Technique: The model utilizes a linear programming
that minimizes delivered cost to all demand sectors.
- Special Features:
- The NEMS residential, commercial, and industrial models provide
demands for those sectors, while the NEMS Petroleum Market Module
provides demands for the coal-to-liquids sector and the NEMS Electricity
Market Module provides demands for the electricity generation sectors.
The CDS provides coal production, Btu conversion factors, minemouth,
transportation and delivered costs for coal supplies to meet these
demands to the NEMS system.
- The CDS interfaces with the international component of the CDS
to determine quantities of U.S. coal export and imports.
- The CDS interfaces with the Coal Market Modules Coal Production
Submodule to receive supply curves that specify the minemouth price
in relation to the quantity demanded. In turn, the CPS receives
production quantities from the CDS that are used to revise its prices,
if necessary, for subsequent iterations
Coal Distribution Submodule (CDS), International Component
- Model Structure: Satisfies coal import demands at the lowest
cost based on specified supply and transportation costs, and subject
to projected overall levels of available coal export capacities by region
and by coal type.
- Modeling Technique: The model is a Linear Program (LP), which
satisfies demands at all points at the minimum overall worldcoal
cost plus transportation cost and is embedded within the Coal Market
Module.

Commercial Sector Demand Module (CSDM)
Description
The NEMS Commercial Sector Demand Module is a simulation tool based upon
economic and engineering relationships that models commercial sector energy
demands at the nine Census Division level of detail for 11 distinct categories
of commercial buildings. Commercial equipment selections are performed
for the major fuels of electricity, natural gas, and distillate fuel,
for the major services of space heating, space cooling, water heating,
ventilation, cooking, refrigeration, and lighting. The market segment
level of detail is modeled using a constrained life-cycle cost minimization
algorithm that considers commercial sector consumer behavior and time
preference premiums. The algorithm also models the minor fuels of residual
oil, liquefied petroleum gas, steam coal, motor gasoline, and kerosene,
the renewable fuel sources of wood and municipal solid waste; and the
minor services of office equipment (with a separate breakout of personal
computers), and other in less detail than the major fuels
and services. Distributed generation and combined heat and power are represented
using a detailed cumulative positive cash flow approach to model penetration
of distributed resources. Numerous specialized considerations are incorporated,
including the effects of changing building shell efficiencies and consumption
to provide district services.

Electricity Market Module (EMM)
Description
The NEMS Electricity Market Module (EMM) provides a major link in the
NEMS framework. In each model year, the EMM receives electricity demand
from the NEMS demand modules, fuel prices from the NEMS fuel supply modules,
expectations from the NEMS system module, and macroeconomic parameters
from the NEMS macroeconomic module and then estimates the actions taken
by electric utilities and nonutilities to meet demand in the most economical
manner. The EMM then outputs electricity prices to the demand modules,
fuel consumption to the fuel supply modules, emissions to the system module,
and capital requirements to the macroeconomic module. The model is iterated
until a solution is reached for that model year. The EMM consists of four
submodules: Electricity Capacity Planning (ECP), Electricity Fuel Dispatch
(EFD), Electricity Finance and Pricing (EFP), and Electricity Load and
Demand (ELD).
Electricity Capacity Planning Submodule (ECP)
The purpose of the ECP is to determine how the electric power industry
will change its mix of generating capacity over the forecast horizon.
It evaluates retirement decisions for fossil and nuclear plants and captures
responses to environmental regulations, such as the CAAA or limits on
carbon emissions. It includes traditional and nontraditional sources of
supply. The ECP also represents changes in the competitive structure (i.e.,
deregulation). Due to competition, no distinction is made between utilities
and nonutilities as owners of new capacity.
Electricity Fuel Dispatch Submodule (EFD)
The objective of the EFD is to represent the economic, operational, and
environmental considerations in electricity dispatching and trade. The
EFD allocates available generating capacity to meet the demand for electricity
on a minimum cost basis, subject to engineering constraints and to restrictions
on emissions such as SO2, NOx, mercury, and carbon.
Electricity Finance and Pricing Submodule (EFP)
The EFP forecasts financial information for electric utilities on an
annual basis given a set of inputs and assumptions concerning forecast
capacity expansion plans, operating costs, regulatory environment, and
financial data. The outputs of the model include electricity prices by
end use sectors for North American Electric Reliability (NERC) and Census
regions, financial statements, revenue requirements, and financial ratios
for each state of production (generation, transmission, and distribution).
Electricity Load and Demand Submodule (ELD)
Broadly speaking, the ELD submodule has been designed to perform two
major functions:
- Translate total electricity consumption forecasts into system load
shapes
- Translate census division demand data into NERC region data, and
vice versa
Emissions
The EMM tracks emission levels for sulfur dioxide (SO2), nitrogen oxides
(NOx), and mercury (hg). Facility development, retrofitting, and dispatch
are constrained to comply with the constraints to the Clean Air Act Amendments
of 1990 (CAAA90), the Clean Air Interstate Rule (CAIR), and the Clean
Air Mercury Rule (CAMR). An innovative feature of this legislation is
a system of trading emissions allowances. The trading system allows a
utility with a relatively low cost of compliance to sell its excess compliance
(i.e., the degree to which its emissions per unit of power generated are
below maximum allowable levels) to utilities with a relatively high cost
of compliance. The trading of emissions allowances does not change the
national aggregate emissions level set by CAAA90, but it does tend to
minimize the overall cost of compliance.

- Economic Sector(s): Electric utilities and non-utilities.
Modeling Features
- Model Structure:
- ECP The ECP is executed once a year to determine
planning decisions that must be initiated in the current forecast
year and completed within the planning horizon. The ECP uses a linear
programming (LP) formulation to compete options for meeting future
demands for electricity and complying with environmental regulations.
It selects the strategies that minimize the total present value
of the investment and operating costs over a pre-specified period,
subject to certain conditions. These conditions include requirements
that demands for electricity (accounting for seasonal and daily
fluctuations variations and transmission/distributions losses) are
met, minimum reliability requirements are satisfied, and emissions
limits are not exceeded.
- EFD The EFD addresses utility and
nonutility supplies endogenously; i.e., the EFD dispatches new nonutility
sources together with utility fossil-fuel, geothermal, biomass,
and nuclear generating capacity. However, existing nonutility supply,
along with nontraditional cogenerators, are considered must
run: units and are placed such that they are always dispatched.
Most of these facilities have contracts with utilities to purchase
power, so this treatment ensures that the model output reflects
actual usage. Traditional cogeneration and intermittent renewable
technologies are represented exogenously with the load curve adjusted
prior to dispatching other generating technologies.
- EFP The EFP is an accounting system that
models regulatory and competitive markets and is completely deterministic.
It has solution algorithms for the generation, transmission, and
distribution stages of production. Pricing mechanisms are implemented
for the generation and transmission stages of production to enhance
the models flexibility in simulating emerging pricing techniques
used in the electric power industry.
- ELD The ELD submodule is designed to be a
fully integrated part of the NEMS framework. The primary functions
of the ELD submodule are to develop regional system load duration
curves from demand estimates for the ECP and EFD modules and to
translate the nine Census division electricity demand estimates
into the 13 NERC regions and subregions that the EMM requires.
- Modeling Technique:
- ECP The ECP uses a linear programming (LP)
formulation to determine planning decisions for the electric power
industry. The ECP contains a representation of planning and dispatching
in order to examine the tradeoff between capital and operating costs.
It simulates least-cost planning and competitive markets by selecting
strategies for meeting expected demands and complying with environmental
restrictions that minimize the discounted, present value of investment
and operating costs. The ECP explicitly incorporates current emissions
restrictions and provides the flexibility to examine potential regulations
such as emissions taxes and carbon stabilization.
- EFD The EFD uses a linear programming algorithm
to provide a least-cost solution to allocating (dispatching) capacity
to meet demand. Dispatching involves deciding what generating capacity
should be operated to meet the demand for electricity, which is
subject to seasonal, daily, and hourly fluctuations. The objective
of the EFD is to provide an economic/environmental dispatching procedure.
In an economic (least-cost) dispatch, the marginal source of electricity
is selected to react to each change in load. In environmental dispatching,
the demand for electricity must be satisfied without violating certain
emissions restrictions. The EFD integrates the cost-minimizing solution
with environmental compliance options to produce the least-cost
solution that satisfies electricity demand and restricts emissions
to be within specified limits.
- EFP The EFP is an accounting system that
models regulatory practice and is completely deterministic. It also
determines prices in a competitive market. It has solution algorithms
for the generation, transmission, and distribution stages of production.
Pricing mechanisms are implemented for the generation and transmission
stages of production to enhance the models flexibility in
simulating emerging pricing techniques used in the electric power
industry. There are many pricing mechanisms that could be used for
this purpose. The regulated price uses the traditional cost of service
method based on average costs. The competitive price utilizes marginal
cost pricing. The modular design of this submodule will allow the
user to plug in additional pricing methods as they are needed in
the future.
- ELD The basic algorithm can be thought of
as an end-use building block approach. The system demand is divided
into a set of components called end-uses. The hourly loads for each
end-use are forecast. Next, the hourly loads of each end-use are
summed to yield the forecast of system load at the customers
meters (i.e., hourly system sales). The final step is to simulate
transmission and distribution losses. The regional hourly loads
are calculated as the sum of hourly system sales and transmission
and distribution losses.

Macroeconomic Activity Module (MAM)
Description
MAM is comprised of three submodules: Macroeconomic, Industry, and Regional.
The Macroeconomic Submodule is the Global Insight Model
of the U.S. Economy and is the same model used by Global Insight Inc.
to generate the economic forecasts behind the companys monthly assessment
of the U.S. economy. The model is a 1,700-equation specification of the
U.S. economy that forecasts macroeconomic driver variables at the national
level of detail.
The Industry Submodule is a derivative of Global Insights
industry and employment models. The models have been tailored in order
to provide the industry and employment detail required by the NEMS modeling
system.
The Regional Submodule was developed by EIA and is comprised
of the Regional Macroeconomic Model, Regional Industry and Employment
Model, and the Regional Commercial Floorspace Model. The first two models
were developed during 2004 for use in the preparation of the Annual
Energy Outlook (AEO) 2005 and the third was re-estimated for AEO2006.

Natural Gas Transmission and Distribution Model
(NGTDM)
Description
The Natural Gas Transmission and Distribution Model (NGTDM) is the component
of the National Energy Modeling System (NEMS) that represents the mid-term
natural gas market. The purpose of the NGTDM is to derive natural gas
supply and end-use prices and flow patterns for movements of natural gas
through the regional interstate network. The prices and flow patterns
are derived by obtaining a market equilibrium across the three main components
of the natural gas market: the supply component, the demand component,
and the transmission and distribution network that links them.

Petroleum Market Model (PMM)
Description
The Petroleum Market Model is a simulation of the U.S. petroleum industry.
It includes 12 domestic crude oil production regions, five refining centers
with full processing representations and capacity expansion capability
and gas plant liquid production, and nine marketing regions. The heart
of the model is a linear program optimization which ensures a rational
economic simulation of decisions of petroleum sourcing, resource allocations,
and the calculation of marginal price basis for the products. Eighteen
refined products are manufactured, imported, and marketed. Seven of these
products are specification blended, while the remaining 11 are recipe
blended. Capacitated transportation systems are included to represent
existing intra-U.S. crude oil and product shipments (liquefied petroleum
gas, clean, dirty) via pipeline, marine tanker, barge, and truck/rail
tankers. The export and import of crude oil and refined products are also
simulated. All imports are purchased in accordance with import supply
curves. Domestic manufacture of methanol and ethanol are represented as
though the processing plants are merchant facilities. Transportation is
allowed for ethanol shipments to the demand region terminals for splash
blending. The program is written in FORTRAN, which includes callable subroutines
allowing full communication with the LP portion of the model, which is
in the form of an MPS resident file.

Renewable Fuels Module (RFM)
Description
The RFM consists of five analytical submodules that represent major renewable
energy resources landfill gas, wind energy, solar, biomass, and
geothermal electric.
The purpose of the RFM is to define the technological, cost and resource
size characteristics of renewable energy technologies. They are provided
to the Electricity Market Module (EMM) for grid-connected
electricity capacity planning decisions. The characteristics include available
energy capacity, capital costs, fixed operating costs, variable operating
costs, capacity factor, heat rate, construction lead time, and fuel product
price.
The Landfill Gas Submodule (LFG) provides the NEMS Electricity
Market Module with annual regional projections of energy produced from
landfill gas. The submodule provides regional forecasts of electric capacity
to be decremented from electric utility capacity requirements, as well
as capital and operating costs for the calculation of electricity prices.
The purpose of the Wind Energy Submodule (WES) is to project
the cost, performance, and availability of wind-generated electricity,
and provide this information to the Electricity Capacity Planning (ECP)
component of the Electric Market Module (EMM) for building the new capacity
in competition with other sources of electricity generation.
The purpose of the NEMS Solar Submodule (SOLAR) is to define
the costs and performance characteristics of central station Solar Thermal
(ST) and Photovoltaic (PV) electricity generating technologies and to
pass them to the EMM for capacity planning decisions.
The Biomass Submodule passes to the EMM cost and performance
characteristics by EMM regions and years. The fuel component of the cost
characteristics is determined from the regional biomass supply schedules
and then converted to a variable O&M cost.
The purpose of the Geothermal Electric Submodule (GES)

Residential Sector Demand Module (RSDM)
Description
The NEMS Residential Sector Demand Module is an integrated dynamic modeling
system that projects residential energy demand by service, fuel, and Census
Division. The modeling methodology is based on accounting principles and
considers important issues related to consumer behavior. Housing and equipment
stocks are tracked over the forecast period for ten major services. The
major services considered are space heating, space cooling, clothes washing,
dish washing, water heating, cooking, clothes drying, lighting, refrigeration,
and freezers. A logit function is used to estimate market shares of each
equipment technology within each major service based on either the installed
capital and operating costs or the life-cycle cost. Miscellaneous appliance
consumption is calculated as a function of Unit Energy Consumption (UEC),
a measure of energy intensity developed from the Residential Energy Consumption
Survey (RECS) database.
