A regional grid operator manages its energy generation assets along a Production Possibility Frontier (PPF) as shown below, representing the maximum potential capacities of Offshore Wind (WWW) and Solar PV (SSS) using its current resource endowment (such as engineering personnel, specialized vessels, and grid connection hubs).

If the grid operator decides to reallocate resources to increase Offshore Wind capacity, moving along the PPF from point P P\,P in the direction of the arrow, this will:
shift the entire frontier outward because wind technology is inherently more productive than solar.
increase the overall joint capacity of both technologies due to economies of scale.
require a reduction in Solar PV capacity due to the scarcity of fully employed resources.
eliminate the opportunity cost of wind generation because the resources are already specialized.
