Sustainable energy Nuon 2001
• Sustainable energy4.275 million kWh being 15,5% of the whole sale
• “Green Power” for business market12,6 million kWh of which 1,1 from the WAC
• “Natural Power” for retail534 million kWhgenerated out of sun, wind and water
• As from 2002: “Green Power” for retailgenerated out of biomass, wind and water

Reasons for better results
Different mode of operation: Operate on power unbalance market, lower base load.
Note: every 4 seconds new setpoint!
Clear purpose.Power unbalance prices are high! Focus on reliability
Nuon buys coal on Buggenum specification.
