When examining and judging energy prepay unit issuance you have to have regard to the rate, and the likelihood, of a flow of energy over time.

This implies what I have heard described as 'confidence accounting'. ie the probability that a particular flow will be achieved.

Over its design life, a wind turbine will produce a 'pool' of energy production, and part of that will be shared with landlords/communities/maintenance contractors.

The balance is then available to be 'unitised' into prepay electricity units which may - if the electricity sale price is adequate - be sold forward to fund the turbine.

The process of project assessment will be similar to that which Jerome probably makes every day of the week using conventional finance capital.
