Reliability Standard MOD-031-1

MOD-031-1 — Demand and Energy Data

A. Introduction
1.

Title: Demand and Energy Data

2.

Number:

3.

Purpose: To provide authority for applicable entities to collect Demand, energy
and related data to support reliability studies and assessments and to enumerate the
responsibilities and obligations of requestors and respondents of that data.

4.

Applicability:

MOD-031-1

4.1. Functional Entities:
4.1.1 Planning Authority and Planning Coordinator (hereafter collectively
referred to as the “Planning Coordinator”)
This proposed standard combines “Planning Authority” with “Planning
Coordinator” in the list of applicable functional entities. The NERC
Functional Model lists “Planning Coordinator” while the registration
criteria list “Planning Authority,” and they are not yet synchronized. Until
that occurs, the proposed standard applies to both “Planning Authority”
and “Planning Coordinator.”
4.1.2 Transmission Planner
4.1.3 Balancing Authority
4.1.4 Resource Planner
4.1.5 Load-Serving Entity
4.1.6 Distribution Provider
5.

Effective Date
5.1. MOD-031-1 shall become effective on the first day of the first calendar quarter
that is twelve months after the date that this standard is approved by applicable
regulatory authorities or as otherwise provided for in a jurisdiction where
approval by an applicable governmental authority is required for a standard to
go into effect. Where approval by an applicable governmental authority is not
required, the standard shall become effective on the first day of the first
calendar quarter that is twelve months after the date the standard is adopted by
the NERC Board of Trustees or as otherwise provided for in that jurisdiction.

6.

Background:
To ensure that various forms of historical and forecast Demand and energy data and
information is available to the parties that perform reliability studies and
assessments, authority is needed to collect the applicable data.
The collection of Demand, Net Energy for Load and Demand Side Management data
requires coordination and collaboration between Planning Authorities (Planning
Coordinators), Transmission and Resource Planners, Load-Serving Entities and

Page 1 of 10

MOD-031-1 — Demand and Energy Data

Distribution Providers. Ensuring that planners and operators have access to complete
and accurate load forecasts – as well as the supporting methods and assumptions
used to develop these forecasts – enhances the reliability of the Bulk Electric System.
Consistent documenting and information sharing activities will also improve efficient
planning practices and support the identification of needed system reinforcements.
Furthermore, collection of actual Demand and Demand Side Management
performance during the prior year will allow for comparison to prior forecasts and
further contribute to enhanced accuracy of load forecasting practices.
B. Requirements and Measures
R1.

Each Planning Coordinator or Balancing Authority that identifies a need for the
collection of Total Internal Demand, Net Energy for Load, and Demand Side
Management data shall develop and issue a data request to the applicable entities in
its area. The data request shall include: [Violation Risk Factor: Medium] [Time
Horizon: Long-term Planning]
1.1. A list of Transmission Planners, Balancing Authorities, Load Serving Entities, and
Distribution Providers that are required to provide the data (“Applicable
Entities”).
1.2. A timetable for providing the data. (A minimum of 30 calendar days must be
allowed for responding to the request).
1.3. A request to provide any or all of the following actual data, as necessary:
1.3.1. Integrated hourly Demands in megawatts for the prior calendar year.
1.3.2. Monthly and annual integrated peak hour Demands in megawatts for the
prior calendar year.
1.3.2.1.

If the annual peak hour actual Demand varies due to weatherrelated conditions (e.g., temperature, humidity or wind
speed), the Applicable Entity shall also provide the weather
normalized annual peak hour actual Demand for the prior
calendar year.

calendar year.
1.3.4. Monthly and annual peak hour controllable and dispatchable Demand
Side Management under the control or supervision of the System
Operator in megawatts for the prior calendar year. Three values shall be
reported for each hour: 1) the committed megawatts (the amount under
control or supervision), 2) the dispatched megawatts (the amount, if any,
activated for use by the System Operator), and 3) the realized megawatts
(the amount of actual demand reduction).
1.4. A request to provide any or all of the following forecast data, as necessary:

forecast compares to actual controllable and dispatchable Demand Side
Management for the prior calendar year and, if applicable, how the
assumptions and methods for future forecasts were adjusted.
1.5.5. How the peak Demand forecast compares to actual Demand for the prior
calendar year with due regard to any relevant weather-related variations
(e.g., temperature, humidity, or wind speed) and, if applicable, how the
assumptions and methods for future forecasts were adjusted.
M1. The Planning Coordinator or Balancing Authority shall have a dated data request,
either in hardcopy or electronic format, in accordance with Requirement R1.

Application Guidelines
Rationale

During development of this standard, text boxes were embedded within the standard to explain
the rationale for various parts of the standard. Upon BOT approval, the text from the rationale
text boxes was moved to this section.
Rationale for R1:
Rationale for R1: To ensure that when Planning Coordinators (PCs) or Balancing Authorities
(BAs) request data (R1), they identify the entities that must provide the data (Applicable Entity
in part 1.1), the data to be provided (parts 1.3 – 1.5) and the due dates (part 1.2) for the
requested data.
For Requirement R1 part 1.3.2.1, if the Demand does not vary due to weather-related
conditions (e.g., temperature, humidity or wind speed), or the weather assumed in the forecast
was the same as the actual weather, the weather normalized actual Demand will be the same
as the actual demand reported for Requirement R1 part 1.3.2. Otherwise the annual peak hour
weather normalized actual Demand will be different from the actual demand reported for
Requirement R1 part 1.3.2.
Balancing Authorities are included here to reflect a practice in the WECC Region where BAs are
the entity that perform this requirement in lieu of the PC.
Rationale for R2:
This requirement will ensure that entities identified in Requirement R1, as responsible for
providing data, provide the data in accordance with the details described in the data request
developed in accordance with Requirement R1. In no event shall the Applicable Entity be
required to provide data under this requirement that is outside the scope of parts 1.3 - 1.5 of
Requirement R1.
Rationale for R3:
This requirement will ensure that the Planning Coordinator or when applicable, the Balancing
Authority, provides the data requested by the Regional Entity.
Rationale for R4:
This requirement will ensure that the Applicable Entity will make the data requested by the
Planning Coordinator or Balancing Authority in Requirement R1 available to other applicable
entities (Planning Coordinator, Balancing Authority, Transmission Planner or Resource Planner)
unless providing the data would conflict with the provisions outlined in Requirement R4 below.
The sharing of documentation of the supporting methods and assumptions used to develop
forecasts as well as information-sharing activities will improve the efficiency of planning
practices and support the identification of needed system reinforcements.
