In the present invention, a power monitoring unit (330) estimates the integral power consumption on the basis of an obtained actual value or amount of change of power consumption. When the estimated value for the integral power consumption as estimated by the power monitoring unit (330) reaches a prescribed amount of power, a presentation unit (204) presents a warning, on the basis of the power values obtained by a load power meter (340), indicating a list of loads for which the power consumption should be controlled.

According to some embodiments, data about a plurality of remote water devices may be received, and each water device is associated with one of plurality of customers of an enterprise and includes a wireless communication device. Based on data indicative of water usage by a first customer, a first water savings amount may be determined for the first customer in connection with a pre-determined period of time. An allocation of the first water savings amount between the first customer and the enterprise may be dynamically calculated, and an indication of the allocation between the first customer and the enterprise may be transmitted.
