Together, Let's Electrify StrataWattblock is assisting Sydney-based apartment blocks to "electrify" with:
- solar - batteries - EV charging - heat pumps and more Click on the local council area on the right to track the electrification progress of strata schemes in that area if you are an Owner or a potential buyer looking for an eco-apartment. Click on the drop pin for each individual strata for more information on that strata and links to free online calculators and resources. If your strata has installed solar, batteries, EV charging, electricity monitoring, embedded network, EV carshare or has a NABERS rating which is not listed in the drop-pin for your strata scheme, please email us at support@wattblock.com.au

The following graphs show the total number of lots by local government area and the total number of strata schemes by local government area. City of Sydney has the highest density of overall strata lots at 112,267 (meaning the biggest strata buildings are in the City of Sydney) while Randwick has the most overall strata schemes at 2,782.
When we look at the spread of strata buildings with different numbers of lots, Randwick has the most strata schemes within the category of 6-10 lots, Inner West has the most strata schemes within the category of 11-20 lots and the City of Sydney has the most strata schemes in every category from 21-50 lots or above.
From a population of 16,680 strata schemes in high density areas of Sydney, the following are estimated take-up rates of electrification in residential apartment buildings.

For comparison, the take-up rate of solar panels on residential houses is approximately 37%, which is the highest take-up rate of rooftop solar globally. Sydney-based strata schemes are at approximately the same adoption rate for solar, that residential houses in Australia were at in 2009, so there is plenty of work to be done in electrifying Sydney-based strata buildings.
