Community Solar Farm And Smart Metering Projects Community Solar Farm And Smart Metering Projects

1.Partnership between DEEDI and WBWC to build first community solar farm in Queensland. 2.Hoped to have had it constructed by this conference but some delays in tendering. 3.Successful technical partner announced last week - Ingenero. Community Solar Farm

1.2.7Mill project funded by the State Government under clean energy initiatives 2.Construction to be completed by March KW individual solar panels 5.Area of the farm – 2600 meters square 6.Generation Capacity – 630 megawatt hours annually 7.Power for 100 homes 8.Annual income returned to the community via WBWC. Technical Details

1.Greenhouse gas emission offsett – 600 tonnes 2.Part of Corporate Strategy to be carbon neutral. 3.Potentially to be expanded through community investment in the future. 4.Based on models from Europe – Spain 5.Potential to move to a more cost effective – Feed In Tarriff Technical Details

1.Government also investing $1.3M in solar for the Hervey Bay Hospital 2.Construction to be completed by March Potentially to be expanded through community investment in the future. 4.Based on models from Europe – Spain 5.Potential to move to a more cost effective – Feed In Tarriff 6.The current policy environment sees risky household systems heavily subsidised this can potentially be a way to enhance well managed solar that the community can invest in. Technical Details

Smart Metering in Hervey Bay Automated Meter Reading Logging hourly water use Radio transmitter mounted on water meters Vehicle-mounted or hand-held data receivers Meter readings sent by radio signal from meter to receiver The logger can record a meter reading every minute or every hour of the day.

Key Objectives 1.Disaggregate annual peak demand into average usage volumes per hour 2.Determine the percentage of hourly usage that is most price responsive 3.Given that there is significant proportion of price responsive water use, construct a suitable TOUT that would target that usage.

Key Outcomes Literature Review 1.Indoor use is predominately price in-elastic 2.Outdoor water use is discretionary and affected by pricing and other interventions.

Key Messages The Annual Maximum Peak Hour annual peak hour consumption is per cent higher than the average daily (morning) peak consumption % of total annual peak hour consumption is single residential consumption greater than 300 litres per hour only 105 out of 2884 single residential connections registered consumption more than 600 litres during the annual peak hour; per cent of total annual peak hour consumption is single residential consumption greater than 600 litres per hour

The Annual Maximum Peak Hour And Its Impact on Infrastructure 10 year capital program has the following allocations: $35M Trunk/Mains Infrastructure – Peak Hour $1.4M Pumping to Distribution – Consumption volume $38M Headworks (Source and Treatment) – Weekly, Month, Peak Hour, Overall demand Unless you translate the reduction in peak demand by a peak demand tariff into changes in infrastructure design standards you will not realize the capital savings available. Also it is strongly possible that that the industry has not leveraged the benefit of all the existing demand management work. (i.e leakage, drought, changing stock of products) This is a leadership action which NWC should take forward. Table 39: Annual maximum peak hour consumption by property type and volume range

Core Message If the Water Industry can develop programs To target Peak Demand then significant capital savings are possible
