1. A computer implemented method for determining an optimal firm sales volume for power provided by a renewable energy generation site into a power grid arrangement within a designated time period, the method including:
- 1. Providing a generation output forecast for the renewable energy generation site in the form of at least one distribution forecast,b. Providing a market forecast in the form of at least one distribution forecast,c. Combining each of the market and wind distribution forecasts to provide an array of possible earnings per energy output from the renewable energy generation site,d. Determining from within the array, an appropriate proportion of energy output to sell for maximizing the earnings within that settlement period, and providing that proportion of energy output value as an output value for contribution by the renewable energy generation site into the power grid.

Abstract
A system and methodology for determining optimal sales strategy for power from a wind farm to a power grid for a number of different conditions is disclosed. By defining distributions for the forecast for the output of the wind farm and combining that with a forecast for market conditions it is possible to evaluate optimum values for the volume of power that can be contributed by the wind farm for specific time periods.

12. A computer system configured to provide as an output an estimate of the optimal quantity of energy generated by a renewable energy generation site that should be sold firm for a plurality of intervals within a nominated time period, the system including:
-
a. A datastore having a plurality of data feeds; i. A first feed coupled to a renewable energy generation site and configured to receive data pertaining to climatic conditions at that renewable energy generation site, ii. A second feed coupled to a renewable energy generation site forecast engine, the renewable energy generation site forecast engine configured to receive from the datastore date from the first feed and provide as an output to the datastore a forecast distribution for estimated power output from the renewable energy generation site for specific intervals within a nominated time period, iii. A third feed coupled to a market forecast engine, the market forecast engine configured to provide as an output to the datastore a forecast distribution for estimated prices within the power grid, b. An optimization engine coupled to the data store and configured to use data from each of the first, second and third data feeds to; i. Combine the data from the second and third feeds to provide an array of values for each interval, the array providing a relationship between power output sold from the renewable energy generation site and expected net earnings, ii. Assess the array of value to determine an optimal value of power output for that time period for a specific set of conditions, and iii. Output that optimal value as an output from the wind farm to the power grid for that interval. - View Dependent Claims (13, 14)

- 15. A computer implemented method to optimize the firmly sold contribution of energy from a renewable generation asset to a power grid, the method including the combining each of market and wind distribution forecasts to provide an array of possible earnings per energy output from the renewable energy generation site, and determining from within the array, an appropriate proportion of energy output to sell for maximizing the earnings within that settlement period, and providing that proportion of energy output value as an output value for contribution by the renewable energy generation site into the power grid.
