All the loads in the school buildings are turned off when there are no occupants in the room, except for equipment that is required to operate round–the-clock, such as refrigerators. For the teachers’ quarters, a load limiter device is installed to manage the extra load that may be used. The electricity cuts off automatically when the maximum allowable electricity power and/or daily energy use reaches the allocated quota. The adaptation of the system design concepts has led CKE to be awarded the ASEAN Energy Award 2016 under the Renewable Energy: Best Practice Off-Grid Power category as shown in Figure 11. Figure 8.
