One new, larger Higher Efficiencies power plant will be more efficient than two, smaller, ol der power plants Teller Brevig Mission Less fuel — consumed Reduced — maintenance and operating costs
• Lower Fuel Costs • Wind and Tidal Energies may be – Renewable Available resources can produce energy – An intertie opens without diesel fuel up possibilities for locations of – Less diesel fuel renewable energy consumed = lower fuel cost charges resources
The main power plant can be built to power multiple villages A modular standby power plant in a connected village can power both villages during outages, if necessary New power plants are typically up to 35% more fuel efficient than most current plants
Fewer Fuel Deliveries Lower Fuel Costs Larger tank farms = Deliveries made to lower storage cost one location instead of per gallon two Lower maintenance Safer Environment and operating costs — Fewer opportunities per gallon for fuel spills
Other benefits may include: — Telephone service could be more easily extended to individuals along the route by attachment to the poles — Availability of electric service along the route could increase the land value

We must connect communities We must improve efficiencies We must harness renewables We must train local people We must use less diesel fuel We must each use less energy
