# The money behind transit trade

Public teaching edition · 15 September 2026

Six teaching editions based on the supplied author materials. They retain the reasoning and methodology, with anonymised participant examples.

## What the host receives

The model provides operating light and an agreed income for the host. A supplier or investor funds equipment; ownership, commission and the sale event are agreed beforehand.

## Teaching scenario scale

At 180 million m², 12 W/m² and 4,800 hours, consumption is 10.368 TWh a year. At RUB 9/kWh this costs RUB 93.312bn. An assumed 25% reduction produces RUB 23.328bn in gross savings. The area and parameters are scenario assumptions.

## Savings may cover only part

The original full-unit rotation model, with an 18-month cycle, has annual costs of about RUB 119.4bn and secondary sales of RUB 17.3bn. A target residual of 20% of revenue requires about RUB 132bn more in annual external payments. Host savings do not automatically become operator revenue.

## Conditions for viability

Confirm buyers, installation costs, demand for used units, initial funding and capital costs. Compare full replacement, module replacement and software adjustment. Frequent rotation needs its own economic rationale.
