It helps by:


Managing collective swimming pool, energy demand in such a way as to off-load the Grid and the Electricity Generating Fleet during peak events.

 

Peak demand events place significant strain on the Grid.  Some 20%-45% of the Grid’s infrastructure is built to handle the last 1% of demand (often just a few hours a year).  In Australia, demand peaks typically occur on a hot summer night when everyone switches on the air-conditioning, all the pools are running, and there is no solar panel generation. 


Pooled Energy anticipates such peak demand events via the weather forecast and prepares the pool by managing the chemistry to store extra sanitiser and ‘cleanliness’ in the water. This is typically done the preceding off-peak periods and keeps the pool sanitized with minimal energy consumption through a peak Grid event or Power Generation failure event. Pool power demand can be effectively “switched-off” during peak events and shifted in time to both before and after the peak.


Where there are many pools under management in an area, this reduces the local power consumption and stress on the Grid. Both peak load and load variation are reduced. Peak load reduction reduces the peak cost of electricity on the wholesale market, which ultimately flows through to the consumer.  The ultimate outcome is reduced operating costs for the pool owner.

 

Modulating collective swimming pool energy demand. 


Modulating power demand means varying the aggregate demand of pool pumps and chlorinators, up and down over periods of minutes.  This makes no practical difference to the operation of the pool, but it can make a big difference to the Grid. 


The introduction of solar panels and wind farms has imposed large stresses on the Grid which was not designed with them in mind.   Power at your house comes via a transmission line from the power station and the voltage on it varies quite a lot during the day as demand goes up and down.  The nominal 240 volts can exceed 260V when demand is low in the middle of the night, and sag to under 220V in the evenings when demand is high.  With many solar panels in some suburbs, the voltage can surge to over 300V during strong sunlight, and sag to under 200V when clouds go by or wind drops.  The higher voltage tends to burn out appliances, and the lower to brown out the supply.


Pooled Energy can help the Grid by using its central computer to collectively run the pools in an electricity region opposite to the effect caused by the solar panels and wind farms.  When Grid voltage is high, the collective pools run harder.  When Grid voltage is low, the collective pools run slower.  This damps out the intermittent effects of solar and wind generation at a fraction of the cost of other ways of doing this using conventional methods within the Grid itself.  We expect the Grid to pay for this service and we plan to share some of this revenue with you via a rebate, once we have sufficient pools in your area to be effective in this way.


Overall, the aggregate pool demand of Pooled Energy pools can therefore appear to the Grid like a vast distributed battery. Pools are not batteries, of course, but, to the Electricity Grid, they appear just that way when modulated as described.
