The Power Generators
Looking at the various technologies MODEC currently operates and the mission of producing clean Power with the highest thermal efficiency and lowest carbon foot-print, we initially developed the Power solution using a 30 MW Aero-derivative generator which we developed with a major USA supplier in 2008 (see Table 1 for efficiency comparison of different technologies).

Turbo-Charged Engine | 48.7% | 0.448 |

It seemed a natural fit as we currently own & operate 42 such generators which can produce roughly 43 MW (each) in combined-cycle mode. After sense-checking the market however, we concluded that we needed to develop larger “Base-Load” generators using Industrial Turbines while using our existing Aero-Derivative design for small-scale power-plants and “Peak-Shaving” applications. To this end, we have worked with major suppliers from Europe, Japan, and the USA to develop the following additional offshore “Base-Load” and “Peak-Shaving” solutions.
