Methods and systems for controlling supply of power generated by a weather dependent power generator

A method of controlling supply of power generated by a weather dependent power generator at a plurality of pressure sewer installations, the method operable by a pressure sewer control system comprising a server in communication with the plurality of pressure sewer installations across a communications network, each of the plurality of pressure sewer installations comprising a controller and one or more sewerage tanks, the method comprising:

• determining weather data for a region associated with each pressure sewer installation;
• estimating power generating capability of the weather-dependent power generator of each pressure sewer installation for a time period based on the weather data;
• receiving fluid level data indicative of a fluid level in the one or more sewerage tanks from the controller;
• determining whether a pump action should be instigated by the controller to pump fluid, at a certain time, from the one or more sewerage tanks based on the estimated power generating capability of the weather-dependent power generator and on a predicted use of the pump action based on the fluid level data and historical use data of the one or more sewerage tanks so as to smooth peak demands of a network of the pressure sewer installations without causing an overflow of the one or more sewerage tanks;
• and
• transmitting a pump control instruction to the controller to cause the controller to activate the pump in response to determining that a pump action should be instigated by the controller, wherein the controller is configured to control supply of power generated by the weather-dependent power generator to the pump.
