Systems and methods for solar voltaic disaggregation from metered net load is presented. A processor coupled with memory can be configured to identify, using a model trained for a site electrically coupled with an electricity distribution grid, a tilt, azimuth, and capacity factor for a photovoltaic system at the site. The processor can receive, from a data repository, irradiance data for a first time interval. The processor can determine an amount of power generated by the photovoltaic system during the first time interval based on the irradiance data, the tilt, the azimuth, and the capacity factor. The processor can execute an action related to power delivery to the site based on the amount of power generated by the photovoltaic system during the first time interval.

A renewable power system with a twin-configurable architecture is described. The system includes a renewable energy source (RES), an energy storage system (ESS), and at least one controllable load (CL) (e.g., AI training / datacenter). The system can serve as a baseload or semi-baseload plant for CL(s) and / or as a peaker or semi-peaker plant for an electric grid, or vice-versa, and optionally in parallel, can also provide ancillary services to the electric grid and / or to the CL(s). In certain embodiments, e.g. solar photovoltaic (PV) RES(es), the system can have capacity factors of at least about 60% and up to 100%, higher asset utilization, better economics for the RES-ESS, improved system performance, and lower energy costs as compared with known systems without a CL(s). By making load a variable, and integral part of the system, sophisticated resource allocation strategies, including AI algorithms, can be developed not previously possible with known systems lacking a CL(s).
