Together, Let's Electrify StrataWattblock is assisting Sydney-based apartment blocks to "electrify" with:
- solar - batteries - EV charging - heat pumps and more. A short video on "What is Electrify Strata" can be found here. Join the Electrify Strata community on Whatsapp here. 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. Electrify Strata now covers a total of 49,223 strata schemes across 29 local council areas in Greater Sydney, which is equivalent to 57% of the total strata schemes in New South Wales. The coverage is below.
If your strata has installed:
- solar - batteries - EV charging - heat pump for domestic hot water - electricity monitoring - embedded network - has an EV on carshare or an eMobility station for e-Bikes - has completed a NABERS for apartment buildings energy rating which is not listed in the drop-pin for your strata scheme, please email us at support@wattblock.com.au. |

A more in depth article on Sydney's higher density urbanisation driving the need for electrification is here.
From a population of 49,223 strata schemes in 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 2011. Strata buildings in Sydney are twelve times less likely to have solar than standalone residences across Australia in 2024. Now that over 250,000 home batteries have been installed in Australia, strata buildings in Sydney are over 100 times less likely to have batteries than standalone houses across Australia. However, Sydney apartment buildings are ahead of U.S. based apartment buildings as can be seen on this video "What can U.S. cities learn from Sydney on electrification of apartment buildings" available here.

Appendix A
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 Sutherland has the most strata schemes at 3,800 (ahead of Canterbury Bankstown at 3,691.)

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.
