Plant requirements

4-

To determine how this demand might be met, CLP produced a detailed "generation plan" of the additions to plant that would be necessary and the date by which such plant would need to be commissioned in order to maintain the supply of electricity at the lowest possible cost.

The necessary increase in capacity is shown below and an outline of the assumptions behind the generation plan is at Annex E;

A final decision on "dual-firing" (that is coal and fuel oil) has not yet been taken.

Cost of capital expansion

9

Assuming that the 4 x 350 mw sets will be dual-fired (were CLP to decide against dual-firing capital costs would be reduced by approximately $700 million), CLP estimate the capital cost of the expansion to their generating and transmission system over the next ten years at $7, 453 million on plant, equipment, land (at full market value) and taking 8% per annum to cover inflation and currency variations:
