E.1
PROJECT DESCRIPTION
Purpose
Gas demand forecasts shall contain two parts: Part I -Gas Demand Forecasts for Eastern and Southern Australia
and Part II -Gas Demand Forecasts for Victorian Declared Transmission System
E.2
Description of Project
Part I
Gas Demand Forecasts for Eastern and South Eastern Australia
The consultant will be required to provide forecasts and reports on gas demand of the eastern and south eastern
Australia each year from 2011 to 2013, satisfying the following requirements.
E.2.1.
Forecast period, demand groups and demand areas

Annual demand for 21 calendar years from the base year; the first base year starts from 2011,
the annual demand forecasts will be from 2011 to 2031 inclusive.

Annual summer and winter peak day demand for 11 calendar years from the base year; the
first base year starts from 2011, the peak demand forecasts will be from 2011 to 2021
inclusive.

Demand is to be forecasted and aggregated by demand areas – MEL, LMP, SWP, TGP,
EGP, MAP, MSP, SEA, ADL, ACT, SYD, RBP, QGP, SWQP, CGP, NQGP, BAL; and

by demand group - Tasmania, Victoria, New South Wales (including Australian Capital
Territory), Queensland and South Australia.
E.2.2.
Forecast categories
The detailed projections should be broken down by categories or sectors from which the consultant could
derive the best quality of forecasts. An example of the possible category breakdown is tabulated as set out
below:
 Residential;
 Commercial;
 Small Industrial;
 Large Industrial Demand, including large feedstock and mineral processing demand, excluding
LNG exports.
The gas demand projections should include gas demand from co-generation and tri-generation facilities.
E.2.3.
Forecast Scenarios
The demand forecasts for the base year 2011 are required for three scenarios Scenario A –Fast Rate of
Change, Scenario C – Moderate Rate of Change and Scenario E – Slow Rate of Change, as set out as
below.
Scenario A
Scenario B
Scenario C

The full detailed description of the five above mentioned scenarios can be found in the section 2.3 of the
‘2011 National Transmission Network Development Plan - Consultation Paper7’ published on the AEMO
website.
The service provided is requested to provide the cost of developing forecasts for extra two scenarios
Scenario B–Uncertain World and Scenario D–Independent Climate Action, identifying differences in
assumptions, and an approach for developing additional scenario forecasts.
AEMO may provide different forecast scenarios on a yearly basis when necessary.
E.2.4.

Annual and peak day demand scenarios forecasts
Annual demand scenarios forecasts
Annual demand forecasts for each demand group, and for each demand area individually are
required for each forecast category and for each year for 21 calendar years from the base year
and for each demand scenario.

Annual peak day demand scenarios forecasts
Forecast system maximum daily (i.e. peak day) gas demands are required for each forecast
category and for 11 years from the base year for both winter and summer peaks by demand area
and by demand group for each demand scenario; and based on:


E.2.5.
1 in 2 winter peak day and 1 in 20 winter peak day weather conditions; and
1 in 2 summer peak day and 1 in 20 summer peak day weather conditions.
Diversity information (optional)
With peak gas demand forecasts for large industrial demand, core demand and GPG, each being
developed separately via different processes, combining these forecasts into peak “total demand”
forecasts presents a challenge due to the natural diversity of these consumer groups.
The consultant is requested to undertake the following with respect to this problem of peak gas demand
diversity:



describe this diversity issue; and
present assumptions and methodology to address the diversity issue; and
present options for progressing the diversity issue going forward
The diversity issues between demand groups and between demand areas within a demand group are also
encouraged to be discussed when appropriate.
E.2.6.
Forecast Methodology
The consultant will be required to provide detailed information on the assumptions, methodologies,
forecasting models, limitations and the analysis of forecasting results.
The following should also be noted:


7
forecast methodologies should be able to reflect gas prices-demand elasticity;
consistency with AEMO’s scenario assumptions is essential in relation to economic, climate
change policy forecasts and carbon policy forecasts;
‘2011 National Transmission Network Development Plan - Consultation Paper’ under 2011 National Transmission Network Development
Plan Consultation at the AEMO website http://www.aemo.com.au/planning/ntndp2011consult.html.
