Tools

Tool	What it answers
grid_context	Everything around one site: county, likely serving utility, 3 nearest substations, transmission lines, ERCOT queue projects and planned transmission upgrades within 25 miles.
nearest_substation	Closest substations to an address or coordinate, with voltage, owner and distance in miles. Filter by minimum kV.
find_powered_land	Parcels near a qualifying substation, by county or point and radius, with acreage and distance to the substation.
ercot_queue	ERCOT generation and storage interconnection projects near a site or in a county: fuel, MW, study status.
upgrade_to_pro	Pro checkout link. Muse and other agents can buy Pro for a user with Link after the user approves.

Inputs take a street address, a Texas city or county name, or lat + lng. Distances are in miles. Texas only.
