At some point the turbines may have to be treated as part of the infrastructure, rather than part of the production.

If you produce energy, you get paid for it, but also pay a levy depending on how well your supply fits the demand. The levy goes to whoever fills in the gaps.

Some deregulated markets are already paying for the turbines as infrastructure.

For example, the PJM interconnection holds an annual capacity auction. This essentially pays for the capital costs of keeping gas turbines around, at idle. The cost of actually running the turbines is covered by a separate daily auction for actual electricity production.
