1. Ramea Island

Island of Newfoundland

World class wind resource

Potential for many 100s of MW

Ramea Island

Not connected to Island grid Ferry access only ~ 350 customers 1,078 kW peak load (winter)

+12 months of successful operation: CF = 0.33 Wind production ~ 1 million kWh electricity / yr Diesel fuel savings ~ 10% ~ 750 tonnes / yr GHG emissions reductions Improved air quality

2. Background

Commissioning of first Wind-Dieseldemonstration project in Canada in

2004 NRCans unique control

system integrates wind

with existing diesel generation

Windmatic 65 kWTurbine

Town of Ramea

Current Situation on Ramea

Installed wind capacity: 6 x 65 kW = 390 kW

Real wind capacity: 390 kW x 0.33 = 129 kW

Total energy produced = 4,201 MWh in 2005 Diesel / Wind (90% / 10%)

Wind-Diesel System in Ramea,Newfoundland

Installed diesel capacity:3 x 925 kW = 2,775 kW

Often one only diesel generator running at 300 kW

Excess wind energy is dumped,therefore, storage would increasewind penetration

Potential for Commercialization

Existing NL Hydro isolated diesel systems:

Significant potential for deployment in remote communitiesin Canada and around the world

A. Feasibility study Modelling and feasibility study done by NRCan

Goals: Establish potential for hydrogen storage andcontribute to equipment sizing

B. Implementation on Ramea Led by Newfoundland and Labrador Hydro Other Canadian Federal Government funding:

$3M CAD confirmed, $1.7M CAD pending

Preliminary Estimate Work backwards from genset

requirement to determine howlarge storage needs to be

Genset H 2 consumption: 250 Nm 3/hr

Hydrogen Storage / Compression

Min genset autonomy: 8 hours8 hr x 250 Nm 3/hr 2000 Nm 3 required storage

At 6700 psi (typical steel storage), require6837 L H 20 equivalent volume

Preliminary Estimate

Work backwards from storage requirement todetermine minimum electrolyzer H 2 production

Maximum time to fill H 2 storage: 24 hrs2000 Nm 3 / 24 hrs = 79 Nm 3/hr

Control System

Control system must work with eachcomponents control system and with the

existing wind-diesel control system

Enercon E33 Turbine

Must optimize each components

production so that overall windpenetration is maximized
