Sustainable Energy Future |
Even with a local sustainable community energy system grid connection (in practice the local distribution system, not the national grid) would be required to provide standby and top up supplies to guarantee energy supply to customers 24 hours a day all year round and to export surplus power over public wires to other customers.
This concept is also important to the future development of sustainable energy stations in the licensed distribution area since energy stations can be configured to supply standby and top up to each other under an enabling agreement for exempt supplier operation. With the development of further sustainable energy stations in the future it would be possible for such island networks to be completely independent of the national grid relying only on the interconnection between sustainable energy stations via the local licensed distribution system which would enable the CHP units to be replaced by renewable cogeneration systems (most likely fuel cells because of the renewable fuel flexibility) in the future when the cost of such systems will be economically viable by the time the generation prime movers require replacing.
In this way, substantial reductions in CO2 emissions and full independence of the national grid with local communities trading surplus power with each other on local lower voltage public wire distribution systems can be achieved with any shortfall in the residential/SME sectors being achieved by domestic CHP and/or renewable energy systems. |
