Three primary solutions are currently employed, and now, with the cost of utility-scale batteries significantly dropping, a new alternative solution has emerged. And with this comes additional revenue opportunities for CRE Developers.
To recap on existing Secondary Power Source solutions for AUTOParkit, AUTODockit, and AUTOStorit systems, Dasher Lawless would recommend at least one of the following to be adopted:
- At a minimum, include a Generator Port in the switchgear to allow a portable generator to be connected. Helms Bakery.
- Install an on-site generator connected to the switchgear with an Automatic Transfer Switch (ATS). The on-site generator is powered by another power source (e.g., natural gas or diesel). INclave.
- Provide multiple circuits supplied by the same or different electric utility companies. PRESS/321 Building.
A fourth option would be a BESS (Battery Energy Storage System) that allows for the battery to be charged from a renewable energy source (e.g., solar or wind), an on-site generator, or low-demand periods from an electric utility company. There are cases when an electric utility company will give the energy away.
A BESS, when paired with an AUTOParkit System, is used to allow the System to run in a low-power mode or retrieve-only mode until the primary power source is restored. Another alternative with a secondary power source is to provide power for charging EVs. This allows the Developer to increase margins on the sale of electricity since energy is purchased at a rate lower than normal. What is also converging is a virtual BESS, which a utility company can locate battery containers in different sites but virtually link them to act as a single larger BESS to provide backup to a garage and also discharge to the Electrical Grid, providing the Developer another revenue stream.
An AUTOParkit System is categorized as a continuous automation application, but unlike its counterparts has a relatively low duty cycle (10% or less per day). Capitalizing on these two characteristics creates an ideal fit for BESS technology to integrate as a secondary power source.
