What is “Reserve”?

• Energy Source used when

Wind is Unavailable

• Generated from mainly

imported fuels – oil, gas,

electricity

• Petrol, Diesel used in the

case of a Plugin Hybrid EV

• (Kerosene for Heat)

• Power Station

• Diesel

Conclusions of Study

• Conclusion:

– There is sufficient Wind & Wave resource accessible to supply ~70% of Electricity, Heat & Transport.....but intelligent energy storage technology is required

– Irish Government Target is 16% Renewable Supply by 2020

3MW Cable

Gaotha go Rothaí Project Rationale

• Develop an Intelligent Autonomous Control System which

– Maximises Wind in Transport Usage

– Minimises Energy Costs

– Meets Customers consumption

requirements reliably

– Provide Blue Print for a National

System

• Demonstrate benefits of EVs

– Low fuel cost

– High reliability and low maintenance costs

– Increases future sustainability of

life on our islands

The Components

• Smart Charger Unit

– Smart Meter

– Timer Switch

– GSM Transmitter

– 3hr Charge Over-Ride Button

• Remote Receiver – Dublin

– 24hr electricity monitoring

– Programming of Timers

• Optimiser Algorithm – Remote Server

– Data from Wind Turbines & Market

– Consumption Profile for Trial User

– Daily Instructions to each Smart Unit

The Car – Mega ECity

• 220mpg or 1.3Litres/100km

• Annual Elect = 90-180 Euro

• Up to 80% fuel cost saving

• Range = 60km (max length of Inis

Mór = 15km, speed limit 50kph)

• Max speed = 60kph

• Aluminium Chassis and ABS

Panels – low corrosion

• Regenerative Brakes – reduced brake wear, high efficiency

• Minimum parts count

• Charging at home - not

dependent on boat supplies

Irish Project Contractors

1. Charge Point Manufacturers =

2. Electric Vehicle Suppliers =

3. Vehicle Owners and Trial = Managers
