Introduction 62

The conceptual model of the smart grid includes a domain called the “Customer” domain. This 63

domain includes the industrial, commercial, and residential buildings and equipment. In order to 64

identify the energy usage information that needs to be shared between the customer domain 65

and other domains within a smart grid, a set of use cases have been defined. These use cases 66

identify the information that passes across a conceptual boundary into or out of the customer 67

domain called the Energy Services Interface (ESI). The physical instantiation of the ESI has, by 68

choice, not been identified. It may be embedded in a meter, utility equipment, or customer 69

premises equipment without changing the use cases. These use cases are contained in a 70

document entitled, “Energy Information Standards (EIS) Alliance Customer Domain Use Cases”, 71

Version 2.0, March 22, 2010. 72

This document identifies the requirements for the information that is passed between the 73

customer domain and the remainder of the smart grid. An effort was made to try to use existing 74

information standards, as applicable. In areas where there are substantial efforts underway to 75

define the definition of the information passed through the ESI, this document defers to that 76

work. The information requirements are identified without relation to the specific protocol used 77

to transfer this information. In this way, market forces can determine the appropriate 78

communications protocols used in any particular domain. 79

Glossary 81 Acronym Name Description

CIM Common Information Model

The CIM is an abstract model that represents all the major objects in an electric utility enterprise typically needed to model the operational aspects of a utility. This model includes public classes and attributes for these objects, as well as the relationships between them.

ESI Energy Services Interface

A logical or physical device typically located at the customer facility and used as a communication gateway. The EMS may or may provide the Gateway function. The Energy Services Interface (ESI) permits applications such as remote load control, monitoring and control of distributed generation, in-home display of customer usage, reading of non-energy meters, and integration with building management systems. The ESI may provide auditing/logging functions that record transactions to and from Home Area Networking Devices.

Scope 83

This specification builds upon the “Energy Information Standards (EIS) Alliance Customer Domain 84

Use Cases” document by developing the requirements of the information identified as crossing 85

the ESI boundary from the customer domain to the smart grid. This information is identified in 86

the appendix entitled “Information Exchange Table“, and is shown below: 87

4 Energy Emissions Information used to quantify the environmental burden created during the generation of the power.

5 Present Demand-Aggregated

Instantaneous energy usage of the facility or production site, as an aggregate.

6 Present Demand-Loads

Instantaneous energy usage of the sub loads being monitored.

7 Available Shed-able Load

9 State Change Interval

How quickly sub loads can respond to a shed command to reduce power demand.

10 Existing Demand Thresholds

Existing peak demand in current billing period; existing maximum demand during ratchet demand period

11 Onsite generation capabilities (and availability--spinning and non-spinning reserves)

The on-site generation capabilities, current and future status are summarized.

12 Onsite energy storage (and availability)

The on-site energy storage capacity as well as current and future status is summarized.


13 Onsite thermal storage

The capacity and availability of on-site thermal energy storage.

This specification addresses requirements for the energy information passed across the ESI in an 88

indusrial, commercial, or residential facility. This specification identifies the required information 89

to be exchanged, and uses type names from the CIM where possible. In an application or 90

standard there may be additional information (e.g. time stamps). 91

This document uses modeling techniques to identify a vendor neutral method of exchanging 92

energy information. It is based upon work performed by IEC technical committee 57: Power 93

systems management and associated information exchange. 94

In developing the information requirements, industry, government, and international standards 95

efforts were analyzed to ensure that the information being transferred was complete. This 96

includes data items defined by the American Society for Heating, Air Conditioning and 97

Refrigeration Engineers (ASHRAE), the Environmental Protection Agency (EPA), the Institute of 98

Electrical and Electronic Engineers (IEEE), the International Electrotechnical Commission (IEC), the 99

LONMark association, the National Oceanic and Atmospheric Administration (NOAA), the Utility 100

Communications Architecture International users group (UCAIug), and the ZigBee Alliance. 101

ID2 Power Quality 301

This information provides various attributes of Power Quality on both an instantaneous 302

as well as historical or scheduled (future) perspective. 303

This information is based upon power quality events defined within IEEE 1159-2009. A 304

Service Level Agreement (SLA) between a and an electrical energy provider should be 305

based on an agreed upon number of transients, sags, voltage fluctuations, voltage dips 306

and interruptions, voltage imbalances, power-frequency variations, induced low 307

frequency voltages, and CD in AC networks events defined in the IEEE 1159 standard. 308

A placeholder was added to this information to indicate Quality of Service (QOS), similar 309

to the Availability found in telephony/data systems. In the future we expect the industry 310

to create a metric that defines--"good power", power availability, or Quality of Service. 311

This data item is expected to normally be sourced external to the building by an energy 312

supplier. It may be validated against internal power quality sources. 313

The Power Quality information exchanged across the ESI is defined in Table 2.1. 314

Development of the requirements for pricing information was considered to be 395

premature by the EIS Alliance. The content of this information is current a topic of 396

discussion within the OASIS EMIX standards body and therefore was deferred. The 397

contents of this information will be addressed as an output of the NIST Priority Action 398

ID7 Available Sheddable Load 556

This information contains Individual loads that may be shed to reduce power demand. 557

There are two methods to indicate the amount of sheddable load; explicit or implicit. 558

Equipment using explicit shedding provide the amount of demand that can be shed (KW 559

or KVA) during an event. Equipment using implicit shedding indicates the percentage of 560

energy demand that can be reduced. The priority of the load gives a relative indication 561

of its criticality within the facility. The Description is intended to be a locally generated, 562

human readable, description of the load. It is intitially entered by the customer. The 563

Identifier is a unique indication of the load within the facility, generated and managed 564

locally by an energy/load management system. 565


management system. Note that since the “Identifier” in this data structure is locally-567

assigned, a “load” could actually represent a process; for example, a “load” could be the 568
