ion in graphical form assists in determining any trends and anomalies. Annual and monthly electricity consumption (kWh) and cost total and for each process unit/functional area Annual and monthly electric demand (kW) and cost Rolling average electricity consumption Where data is available also plot average daily and hourly consumption Collect Additional data Most data collected at WWTPs is focussed on compliance monitoring and not energy use assessment. It is therefore necessary to collect additional data fo energy auditing purposes. Some of the additional data that might need to be collected includes: Actual energy consumption and efficiencies of large equipment .. blowers, aerators, diffusers, pumps Seasonal diurnal flow and load patterns to dete rmine peak influent flows and loads and process performance 7 As an example refer to Sections 3 and 4 for the different tariffs for Zeekoegat (owned and operated by the City of Tshwane). he tariff for the plant is an ESKOM time of use tariff) and JP Marais (owned by Ekurhuleni Municipality and operated by ERWAT). The tariff for th plant is not time of use and structured as an ESKOM tariff. 3-1 Wastewater characteristics for application in advanced process modelling to evaluate aeration energy conservation strategies Benchmark and Compare Energy Use The objective of this step is to use the data from the above steps to convert energy use into useful benchmarks that can be used to compare with sim ilar treatment plants and identify energy saving opportunities. The following is required: Identify useful performance measures and calculate energy use intensity8. Calculate total and aeration energy intensities Calculate GHG emissions (carbon equivalent) to generate baseline electricity used Compare total and aeration energy use intensities with both local and international values for similar wastewater treatment plan
