One way to do it is to leave the existing turbine and to add a system that condenses the steam at the turbine's outlet, recovers the latent heat, and generates electricity with it.
Organioc Rankine Cycle (ORC) systems can serve for this, but there's a system called WOWGen that's a dual-cycle (combined cycle) ORC that generates more power. Happy coincidence, I sell those systems. Feel free to contact me at: stratos@spp-consultants.com (I'm in Canada). With some basic information, the power-generation potential and the estimated cost can be determined.
Otherwise, see the website of the WOWGen system manufacturer, WOW Energy: www.wowenergies.com
