Table 5, Summary of the energy costs of double-basin schemes at Fundys Shepody Bay and Cumberland Basin. Costs as shown are based on the use of fish-friendly turbine generators and sluices, equpped with automatic flap gates.

At Fundy, with its specific environmental concerns, only paired-basins Types Z & Z would meet the adopted environmental sustainability standards. |

The 7,200 m long dam required to create the enlarged Cumberland Basin raises the cost of energy for the linked-basins scheme to above that of paired-basins Types X & Y. With a shorter dam at Cumberland basin, the energy cost of the linked-basins could have been 2.9&icent;/kWh. |
