INTRODUCTION

The effort to substantially modernize and transform the national electric grid and create what has become known as
a "smart grid" is an enormous undertaking that reflects both the size and importance of the electric grid. Viewed in
its entirety, it is an international effort involving hundreds of organizations and companies, and it will impact
billions of people. The standards infrastructure that will be needed to support this transformation may include over
one hundred standards by the time that it is fully in place. This standard is one part of that infrastructure.
Almost all electricity is consumed in a building of some kind – homes, retail establishments, offices, schools,
factories, hospitals – the list goes on. This standard attempts to capture the breadth and diversity of these consumers
by using the term "facility." A facility is any kind of building or collection of buildings, and all of the electrical loads
or local generation sources contained within them or controlled by the facility owner.
Historically, electricity consumption has been viewed as a collection of dumb loads at the end of a distribution
system. There has been almost no interaction between the "loads" and those responsible for electricity generations
and distribution. The vision of the smart grid changes this picture radically. In a smart grid world, facilities become
full partners in supporting and managing the electric grid. Facilities become generators using local renewable or
other generation capacity. Facilities moderate electrical demand in response to fluctuations in the price or availably
of electricity. Facilities communicate and negotiate with energy providers, sharing information about the facility's
projected electrical demand or ability to respond to the energy provider's needs for maintaining grid stability and
reliability.
In some respects all facilities have common characteristics and needs with respect to interactions with a smart grid,
regardless of whether the facility is a commercial, institutional, or industrial building, or a private home. The
Facility Smart Grid Information Model (FSGIM) standard attempts to capture this commonality and standardize the
content of the information that a facility manager needs to have, or, in some cases, needs to exchange with the
energy provider, in order to manage the facility. Energy providers benefit from the FSGIM standard because it
enables interaction with all different types of facilities in a common way. Facility owners benefit because products
can be designed for use in multiple facility types and products designed primarily for one type of facility, a home for
example, can more easily be used in another, say a commercial building.
An information model is an abstraction, not an implementation. This abstract representation is a way to account for
the reality that the technology used to manage a facility may be quite different depending on the type of facility. It is
intended that the FSGIM will be used to develop or enhance other standards that define technology and
communication protocol specific implementations of the model for particular markets.
The FSGIM was developed in the context of a much larger framework of smart grid standards. It builds on some of
those standards in a way that is intended to maintain consistency and harmony with established and developing
standards that impact the information needed to managing the facility, while at the same time capturing all of the
key information needed in one place.
If the smart grid is to become a reality there must be smart facilities of all types that interact with it. The
considerable time and talent that went into developing the FSGIM was invested in order to lay a solid foundation
upon which to fulfill this vision.

1. PURPOSE
The purpose of this standard is to define an abstract, object-oriented information model to enable appliances and control
systems in homes, buildings, and industrial facilities to manage electrical loads and generation sources in response to
communication with a “smart” electrical grid and to communicate information about those electrical loads to utility and
other electrical service providers.

2. SCOPE
This model provides the basis for common information exchange between control systems and end use devices
found in single - and multi-family homes, commercial and institutional buildings, and industrial facilities that is
independent of the communication protocol in use. It provides a common basis for electrical energy consumers to
describe, manage, and communicate about electrical energy consumption and forecasts.
The model defines a comprehensive set of data objects and actions that support a wide range of energy management
applications and electrical service provider interactions including:
a) on-site generation,
b) demand response,
c) electrical storage,
d) peak demand management,
e) forward power usage estimation,
f) load shedding capability estimation,
g) end load monitoring (sub metering),
h) power quality of service monitoring,
i) utilization of historical energy consumption data, and
j) direct load control.

3. DEFINITIONS
See Clause 8 for external standards that are referenced by this standard.
3.1. Terms Adopted from External Sources
The following terms used in this standard are drawn from other standards or published reference sources. The
definitions are repeated here and a reference to the appropriate standard or document is provided. Words or phrases
in italics refer to terms defined elsewhere in this clause.

asset
A logical entity with measurable and reportable consumption, e.g., an asset may be a physical device with its own
meter, or the main meter at the service delivery point of a service location.
(NAESB 2010a).

baseline
A method of estimating the electricity that would have been consumed by a customer or demand resource in the
absence of a demand response event. It may be calculated using interval metering and/or statistical sampling
techniques.
(NAESB 2010a).

combined heat and power
Combined heat and power (CHP), also known as cogeneration, is the simultaneous production of electricity and heat
from a single fuel source, such as: natural gas, biomass, biogas, coal, waste heat, or oil.
(http://www.epa.gov/chp/basic/index.html).

electrical coupling point
Point of electrical connection between the DER source of energy (generation or storage) and any electric power
system (EPS). Each DER (generation or storage) unit has an ECP connecting it to its local power system; groups of
DER units have an ECP where they interconnect to the power system at a specific site or plant; a group of DER units
plus local loads have an ECP where they are interconnected to the utility power system.
(IEC 61850 Part 7-420).

energy management system
A system used to monitor and control the energy consuming devices in a building. Within this standard, "energy
management system" always refers to a customer/facility energy management system and not a utility energy
management system.
(EIS Alliance Use-Cases).

(NEMA glossary (http://www.nema.org/gov/energy/glossary/)).

power quality
Characteristics of the electricity at a given point on an electrical system, evaluated against a set of reference
technical parameters.
NOTE: These parameters might, in some cases, relate to the compatibility between electricity supplied on a network
and the loads connected to that network.
(IEC 61000-4-30 (2008)).

pricing node (Pnode)
A single network Node or subset of networked Nodes where a physical injection or withdrawal is modeled and for
which a Locational Marginal Price is calculated and used for financial settlements.
(CAISO Tariff).
