Energy Conservation and CO2 Reduction through Networked Area Energy Use

Networked Area Energy Use mutually accommodates electricity and heat among multiple buildings. This system enables efficient use of electricity and heat utilizing gas CHP, leading to energy conservation and reduction of CO2 emissions.

 

What is "Networked Area Energy Use"?


"Networked Area Energy Use" refers to the idea of mutually accommodating electricity and heat among multiple buildings. In conventional systems, each building uses electricity and heat individually. But in an energy system based on Networked Area Energy Use, electricity and heat are distributed among multiple buildings in order to level out usage patterns of electric energy and thermal energy such as hot-water supply and heating.

Energy conservation and CO2 reduction by electric and heat use in Networked Area Energy Use


『Load Leveling of electricity and heat by the aggregation of multiple customers』
With Networked Area Energy Use, however, intensive consumption of electricity and heat energy differs among buildings depending on the time of day, thus allowing the pattern of energy use to be leveled by mutually accommodating energy sources.
 
『Effect of load leveling』
Compact facility
The capacity of the facility for air conditioning or electricity is designed to match the maximum demand. Load leveling by the aggregation of multiple customers decreases the maximum load, which makes the facility compact.
 
Efficient operation at high load
Load leveling by the aggregation of customers increases the minimum demand and enables a high load factor. In other words, the facility installed is likely to be operated at high efficiency due to the high load factor compared to a system that does not use aggregation.
This increase in minimum demand also increases the capacity of the system installed.
Generally, the efficiency of CHP is improved with an increase in capacity, especially in CHP utilizing a gas engine. This means an additional efficiency improvement can be expected.
