2. Global Offshore Update
A $ Multi-B industry over the next 10 years.
Remarkable growth 15 – 20 % CAGR
Can be sited closer to urban populations
Proximity of local grid connection to urban centers.
Less turbulence and WTG Fatigue
Higher capacity factors – 50%
Cost of electricity approaching 6¢/kWh
Favourable regulatory support.

3. GE Wind Energy – Arklow Project Site Specifics
8.5 m/s wind speed at 73,5 m
10 km from shore
3.5 – 6.4 m water depth
Breaking waves & high currents
Dense sand & gravel
Co-Development project of Airtricity & GE Wind Energy

4. Arklow Background
25.2 MW Demonstration project of GE Wind Energy’s 3.6 MW Offshore Wind Turbine Generator
Project located 10 kms off the coast of Arklow, Ireland in the Irish Sea
7 x 3.6 MW WTGs constructed by GEWE in 2003
GEWE co-developed project with Irish Green energy company, Airtricity
GEWE has built and will own and operate turbines for approximately 2 years, then transfer (BOOT)
45 miles south of Dublin
During Ownership period GEWE will ensure acceptance of:
Basic reliability of design
Necessary operating hours to prove new technology
Warranty provisions and weather exclusions adequate for financing
Optimization of O&M – Cost effective and safe

5. Arklow Update All 7 Wind turbines Pre-Commissioned
3 Wind turbines commissioned & under final testing - expect to generate electricity by 8th March 2004
Remaining turbines 50% commissioned
All undersea cabling connected & tested
Land-based switch house commissioned
Meteorological mast foundation and tower fully installed, monitoring & measurement equipment being installed
Asset Management team in place
Develop World class O&M
Document lessons learned and implement solutions
Completing evaluation of how to optimize access
Completing comprehensive maintenance plan with major EHS focus
Validating plan to jump to 4 MW Wind Turbine

6. Arklow Lessons Learned
Construction
Complete detailed logistics planning early in execution phase
Complete geo-technical analysis early
Develop design sufficiently to minimize changes
Coordinate order placement w/ legal, accounting & tax constraints
Acknowledge EHS risk & convert to competitive advantage
Access…access…access
Contractual
Partner with offshore contractors having skills to take installation risk
Engineering & Supply Chain must be completed ahead of construction window
Manage undersea cable like a separate project
New major components should be managed in a similar fashion to product NPI

7. Arklow EHS Grid Connection Environment & Safety Management Systems
GEWE personnel closely liased with ESB to ensure Arklow Safety Management system interfaced with local Electricity Grid safety boundary documents.
Leverage GE Safe Systems of Work from other GE Energy businesses to suite local legislative requirements
Environment & Safety Management Systems
GE’s global EHS systems recognized as world leaders.
Risk management approach from Corporate level through to a Site’s business plan.
Developing access systems to maximise availability and to suite local conditions.
All offshore personnel are required to attend the BOSIET course(Basic Offshore Survival).

8. Arklow – Objectives and Plans
Environment, Health & Safety
GEWE will be a leader in the Offshore Wind Industry for EHS programs
Active involvement and assessment of all activities from construction to access to O&M
Established environmental monitoring and reporting program
Operations & Maintenance (O&M)
Using 2 year ownership period to develop expertise
Asset Management, Services & Engineering organizations working closely to optimize

9. Arklow – Objectives and Plans
Availability Tiger Team
Multi-discipline team formed to drive reliability
Manage Arklow turbines with high availability objective
Establishing remote monitoring of Arklow turbines through monitoring center in Germany
Assess design and develop redundancy to allow long maintenance intervals. Long term goal is once per year
Access
Evaluating options to optimize access methods considering EHS, availability impact and cost
Recognize EHS risks and looking to set standards
Looking to leverage best practices from other offshore industries
