VTANA
A battery energy storage site in the corner of a working freight yard at sunset, the sun on the horizon: louvered enclosures on a fenced gravel pad, a pad-mount transformer and metering, the pad lights just switched on, and a utility pole carrying the line out to the road.

We carry the evening.

Six o'clock.

Wires move power through space.We move it through time.

Overnight, while the neighborhood sleeps and power is plentiful, we fill.

At six, when the air conditioning surges, the kitchens fire up, and the city comes on all at once — we give it back.

We carry the evening.

STATE OF CHARGE
One day from midnight to midnight, drawn as a machined metal plate. A raised line traces demand on the wire: low overnight, climbing through the day, cresting in the evening. Two copper inlays show what we do — a hatched block filling the overnight trough where we charge, and a solid block cut off the top of the evening crest where we discharge. Two short arcs mark where the wire would have run without us.
One day, midnight to midnight. A line traces what the wire carries: low overnight, climbing through the day, cresting in the evening. Overnight we fill, adding load the wire can easily take. In the evening we give it back, cutting the top off the peak. The dashed line is where the wire would have run without us, and the two shaded areas are equal. 12 AM 6 AM NOON 6 PM 12 AM WE FILL WE GIVE IT BACK NOW

Power is the only commodity sold the second it’s made.

Grain got elevators. Water got towers.

Electricity never got its building.

We give it a shelf.

A working freight yard: semi trailers and tractors parked on the apron, a fenced pad of battery storage and associated equipment in the far corner, a utility pole and distribution line at the road.
