Peer-to-peer trade for surplus on-site generation (local flexibility market)

Hi OpenStudio/EnergyPlus developers and users,

I hope this message finds you well.

I would like to ask a question regarding the potential for simulating a local energy flexibility market using OpenStudio/EnergyPlus.

Specifically, consider a scenario involving two buildings simulated within OpenStudio/EnergyPlus: one equipped with on-site generation (e.g., PV systems), and the other without. During certain hours, the building with on-site generation produces surplus electricity. I am wondering whether it is possible, instead of exporting this excess energy to the grid, to simulate the transfer of this energy directly to the other building.

In essence, this would require modeling two distinct electricity purchasing mechanisms: one from the main utility grid and another from neighboring buildings within a local energy network.

I am not sure whether OpenStudio/EnergyPlus currently supports such a capability and would greatly appreciate your insights or any possible workarounds to model this functionality.

Thank you very much for your time and support.

Sincerely,

The issue names no source files, tests, or entry points. Start by checking current OpenStudio and EnergyPlus support for multiple buildings, surplus generation, and inter-building electricity flows; define the required modeling behavior and a validation scenario before estimating implementation work.
