NOVELTY - The method involves entering into a master power purchase agreement with a utility company to sell power generated by a power generation facility to the company for a negotiated price. Rights in individual power generation units are transferred to individual investors. The investors are entered into subsidiary power purchase agreements to purchase the power for another negotiated price. The power is supplied to a public power grid, where the supplied power is individually measured by the units to allow accounting to the investors for the power contributed by the respective units.    USE - Method for operating a renewable energy park e.g. large scale solar farm and wind farm, which is used for generation of power from renewable energy sources e.g. wind and sun.    ADVANTAGE - The method allows the individual investors to enter into the subsidiary power purchase agreements to purchase the power generated by the individual power generation units for the negotiated price at the end of the lease term, so that the lease term is set to enable the operating company to fully realize depreciation and other tax benefits and the purchase price in the lease is set to provide an acceptable return on investment to the investors, thus enabling the ordinary consumers to invest in renewable energy and the investors to benefit from the economies of scale of the large-scale power generation facility and from the cost savings due to tax credits and depreciation that is to be passed to the investors through the sub- power purchase agreements. The investors can hence purchase as many individual power generation units to provide all or part of the energy needs of the units, and the investors cannot be burdened with engineering and maintenance of the energy generating assets, so that the cost of electricity produced by the renewable energy park is reduced in an effective manner.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a power generation facility having power generation units, individual power meters and a computer.    DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a method for operating a renewable power generation facility by an operating company.
