Asts-less block redundant electrical topology with variable ups walk-ins

A method for power distribution, the method comprising:

• supplying power from a utility to a critical load via a primary power system comprising a primary UPS coupled to a primary power source via a primary input, a critical load via a primary output, and a reserve power system via an automatic bypass input;
• detecting an outage of the utility by monitoring the power received via the primary input of the primary UPS;
• supplying power to the critical load using a stored energy device in response to detecting an outage of the utility;
• monitoring the capacity of the stored energy device while supplying power to the critical load using a stored energy device;
• transmitting an on bypass request to the reserve power system upon determining that the capacity of the stored energy device has reached a pre-determined threshold, wherein the on bypass request is transmitted from the primary UPS to a switchboard of the reserve power system;
• determining that the reserve power system is able to support the critical load;
• and
• transferring the critical load to the reserve power system if the reserve system is able to support the critical load, wherein transferring the critical load to the reserve power system comprises coupling the critical load to the switchboard via an automatic bypass input of the primary UPS.
