Technical directives for planning of energy internet
1 Scope
This document specifies the general requirements, energy demand and supply forecasts,
energy balance, energy internet architecture, energy internet planning and construction,
multiple interactions, technical and economic analysis, as well as other requirements,
for planning of energy internet.
This document is applicable to works related to the planning, design and construction
of energy internet.

advanced energy technology, it supports clean and low-carbon transformation of energy,
optimization of comprehensive energy utilization efficiency, and flexible and
convenient access of multiple subjects.
4.2 Energy internet planning shall give priority to the use of renewable energy
according to regional resource endowment and energy supply and demand
characteristics, and achieve the goals of improving clean energy consumption capacity,
comprehensive energy utilization rate and user energy supply quality through optimal
allocation, coordination and complementarity, and efficient utilization of various energy
sources.
4.3 Energy internet planning shall ADHERE TO the concept of system planning,
FOLLOW the principles of “source-network-load-storage collaborative interaction,
power-heating-cooling-gas multi-energy complement, and energy information deep
integration”, CARRY OUT overall optimization around key links such as energy
production, conversion, transmission, and storage, CARRY OUT overall design in
combination with key aspects such as physical architecture, information architecture,
and communication architecture, and COORDINATE the internal composition, spatial
layout, and timing arrangement of each planning element, to achieve the optimal overall
energy utilization efficiency.
4.4 Major cities and disaster-prone areas shall carry out disaster prevention construction
of key energy supply facilities, appropriately improve construction standards, and
enhance the disaster prevention and emergency support capabilities of the regional
energy internet.
4.5 The technical and economic evaluation of energy internet planning shall adhere to
the basic principle of “combining quantitative and qualitative evaluation, with
quantitative as the main and qualitative as the supplement”. Quantitative evaluation
shall be based on the data information in the reasonable assumptions of the energy
internet for quantitative and accurate evaluation; qualitative evaluation shall carry out
a comprehensive evaluation of the energy internet.
4.6 Energy internet planning shall be incorporated into local land and space planning,
with facility corridor land rationally reserved for multiple types of energy such as
electricity, heat, and gas. Energy internet facilities shall be planned simultaneously with
other urban and rural infrastructure, and the layout of facilities shall meet the
requirements of national laws and regulations on environmental protection, soil and
water conservation, and ecological environment protection.
5 Energy demand and supply forecasting
5.1 General requirements
5.1.1 Energy demand and supply forecasting, the basis of energy internet planning and
design, includes forecasts for the demand and supply of energy such as electricity, heat,
cold, and gas, as well as forecasts for the development of various energy sources such
as coal, oil, natural gas, hydropower, solar energy, wind energy, nuclear energy,
geothermal energy, biogas, and tides in the region.
5.1.2 The load development characteristic curve, which shall be determined according
to regional characteristics, social development stage and user type, shall be used as the
basis for planning.
5.1.3 The basic data for energy demand and supply forecasting shall include economic,
social and natural climate data, forecast results of the planning area by the higher-level
energy internet planning, historical annual energy load and supply data, etc., including
historical data of year, month, day and other time scales. Energy internet planning shall
accumulate and use a series of standardized historical data of energy demand and supply
as the basis for forecasting.
5.1.4 Energy demand and supply forecasting shall adopt various methods, and, after
comprehensive analysis, provide three schemes of high, medium, and low levels of
demand and supply forecasting results, and put forward a recommended scheme.
5.1.5 Energy demand and supply forecasting shall determine the total forecast results
of energy demand and supply, and should carry out forecasts by categories and regions.
The short-term forecast results shall be listed year by year, and the mid-term and long-
term results can be listed at the end of the planning.
5.1.6 The investigation and collection of data shall be done through various channels.
