ENERCON Service Concept

• Service is as important to ENERCON as producing and selling wind turbines.

• High performance, reliable turbine operation is the cornerstone of ENERCON’s culture.

• Responsibility for long term operation = vested interest in quality

• Affects all aspects of the company

• Quality engineering

• Control over manufacturing

• Careful client and site selection

• Secure replacement parts supply

• Service � Parts Refurbishment � Manufacturing � Engineering feedback loop

• No “sell-and-run“ attitude! We look for an excellent 20-year relationship with the customers and their

turbines.

The Issue

• After planning, finance and building – the work is not over

– Upkeep of wind turbines is a crucial issue

• Choice between OEMs and ISP after the initial warranty period

– ISPs sometime require a certain volume of work to ensure ready availability and

comparable service levels

– OEMs seem reluctant to share information

• Projects have not properly factored in the ongoing O&M costs to keep a plant running efficiently

– Low plant availability accounts for half of an approximate 10% gap between pre-

construction estimates of power production and actual production

• The Goal: cost competitive Availability (and happy customers, too!)

10


Spare Parts

• Many plant owners are struggling with underperforming wind projects and higher service costs due to poor spare part availability

• OEMs:

– Have better access to spare parts because of their volume and standing

agreements

– Enercon is vertically integrated (manufactures up to 85% of it’s own components)

� Not subject to third party supplier’s part availability

– Need to keep an inventory (for ISPs, inventory can represent money lying

around)

• ISPs:

– Disappearance of some companies whose machines continue to turn over the

years

• Owners need to implement a spare part strategy early on (e.g. allocate money for delivery of some spares

– Useful hedge against a gearbox failure and potential downtime (6 months)

11


Experience

• “The wind industry’s rapid growth appears to have outpaced it’s ability to recruit and

train staff” – WindPower Monthly Magazine, January 2011

• The growing range of machines is causing problems

• “Cost-effective maintenance is having an experienced staff who know all the

particulars of specific turbine models and are able to turn a mass of data into usable

and actionable information. Raw data is useless unless it is understood and applied”

• OEMs have access to all the information they need to properly service and adapt if

required

– Many opportunities for improvements and retrofits

12


Integration

• Vertical integration leads to alignment of incentives

• The basics:

– Build it properly and you’ll save costs on O&M

– Operate and Maintain your turbines properly and you’ll sell more turbines

• Being involved in various stages of the process leads to

– More comprehensive warranties

� Lower insurance premiums, easier access to project funding, reduced long

term investment-risk profile

– Closed-loop feedback with other departments (e.g. R&D, Construction)

• Better maintenance can be a net serving rather than a net cost

13


Estimated Turbine Availability

Third party estimates:

Taking into consideration routine maintenance, fault downtime, minor component failures and

major component failures

14


Availability

• The best measure of profitability is the availability factor

– i.e wind turbine is fully online and able to capture available winds

Arguments are nice, but numbers are better:

CS-66: 99.02% over last 5 years 30,438,639 hours

CS-70: 99.41% over last 5 years 126,637 000 hours

CS-82: 98.62% over last 3 years 52,850,000 hours

As of 10/01/2010

Year of introduction:

E-66: 1995

E-70: 2003

E-82: 2005
