| Introduction of Multi-energy Operation System |
|
|
|
At the Kagoshima Kokubu Plant, a multi-energy operation system was established with optimum operation designed in combination of an existing absorption type refrigerator with a cogeneration system and a high-efficiency turbo chiller newly introduced. Its operation started in June, 2005.
The "multi-energy operation system" supplies the plant power demands with electricity purchased from electric power companies and electricity generated by a cogeneration system and also supplies HVAC demands for air conditioning with an absorption-type chiller and turbo chiller.
This system allows us to reduce CO2 emission and minimize the energy cost by selecting operational mode—using or stopping co-generation, changing chiller operated and/or adjusting operation temperature of each type of chiller—depend on the operation status of the plant, season, time zone and energy cost required. |
| Annual purchasing electricity reduction |
2,300MWh |
| Annual fuel (town gas) reduction |
900,000m³ |
| Annual CO2 reduction 2,851 |
2,851ton-CO2 |
|
| Introduction of Turbo Chillers |
|
|
|
| High efficient turbo chillers can reduce CO2 emissions greatly because it has the higher refrigeration efficiency / primary energy than present absorption type chillers. |
