• How much kerosene was burned to get me from Europe to the US (4000 mile)?

Energy Q&A: how important is it?

63 gallons per person in the plane

• How long does a luggage handler have to load an unload bags before he has spent 1 kWh of physical energy?

5 to 8 hours, as he is likely to use/produce between 125 Watt and 200 Watt

• How many labor hours does a gallon of Kerosene represent if we assume a 50% efficiency?

100 to 160 hours, or up to 4 working weeks of physical labor

• How many hours of energy “life support” does the average American get per year?

Every American has the equivalent 275 “employees” continuously working for him/her.

< 2%• What is the average energy efficiency we reach in modern society?

Transition is in full swing

• Global invesmtents in renewable energy

– 2007: $ 104 B

– 2008: $ 120 B (Coal and gas powerplants combined attracted $ 110 B in 2008)

– 2009: $ 162 B (China $35 B, US $19 B)

– 2010: $ 200 B (?)

• Reasons why this trend will continue

– “Clean Energy Race”, it became strategic

– Business case comes towards us

• Renewable technology improves and its prices decline

• Demand for energy increaeses

• Alternative options increasingly expensive, damaging, cumbersome


Energy Returned On Energy Invested

• Medieval Europe 1,2

• Texas 1900 100, or more

• A good new oil field in 1980’s 30-50

• A good oil field now 10-30

• Clean coal 10-15

• Oil Sands Canada 1,5-7

• Wind Energy 30-50 and improving

• PV Solar power 30-50 and improving

EROI of renewables is guarantee for success

Renewables are good option.....

• Companies are swimming in cash. Due to poor investment climate, cost cutting and lack of good investments.

• US alone $943 B excluding banks, Europe no figures, but same trend

– ICT $ 207 B of which Cisco $40, Microsoft $37B, Google $30B and Oracle $23B,

– Pharmaceuticals: $ 124B

– Energy: $ 105B

– Ford, $22B

• Pressure on mgt increases to look for new opportunities, take overs, share buy back, increase of dividents etc. But good investments are hard to find.

Head out to sea

• US DOE

• Islands: Bonaire


US offshore wind ambitions

• DOE/NREL published excellent new reports

• DOE targets:

– 2020: 10 GW, $0,13/kWh

– 2030: 54 GW, $0,07-$0,09 / kWh

– NREL resources > 4000 GW

• Extremely challenging:

– Current ppa’s: 20-24 cts / kWh

– Regulatory framework is complex

– US energy prices are (still) low

• But Industry is gaining momentum


Offshore Wind Resources (NREL)


Case: Ecopower Bonaire

Stand alone wind-diesel system for the electricity supply of the island of Bonaire


Maximise the wind share in an island grid with very little additional costs

• By using the right wind turbines

• By using the right power management system (PMS) software


The Bonaire Case – 4 years ago

• Inhabitants: 15.000

• Size: 250 km2

• Electricity consumption 75.000 MWh/year

• Peak demand: 12 MW

• Up to 2010: 100% Diesel generation

Broken since 1997Burned down in 2005

Stopped operation in 2006Running…..


The Bonaire Case – now

• New wind-(bio)diesel system developed, financed, installed

• In operation since August

• 40-45% wind share

• Potentially 100% renewable

Broken since 1997Burned down in 2005

Running…..


History

• 2005: Main power plant burned down

• Kema and Ecofys performed study for energy sector.

Conclusion wind-diesel is best option

• Spring 2006: Tender for wind-diesel system

May 2006: consortium of Econcern, MAN and Enercon submitted winning bid

September 2006: MoU signed with Bonaire Utility “WEB”

November 2007: PPA signed


Project concept


The project concept

Why is it so special?

• PMS maximises wind share

– Up to 80% instantaneous wind share possible

– Target Bonaire is 40-45% on average

• Only possible with “smooth electrical behaviour” of

Enercon wind turbines

• Battery of 3 MW added to:

– improve grid quality

– reduce spinning reserve

• Extra costs are limited to 0.5 - 1.0% of capex!

Wind Turbine Sorobon

Broken since 1997 In operation, since July 2007:

Replaced by Ecopower 4600 FLH, 99% available


Wind Farm Morotin

Visual of wind farm with 12 windturbines

Most reliable and low maintenance WTs

Deliberate choice for smaller WTs

Fuel save warrantee


Wind Speed Measurements


Power House Karpata

Reliable and (relatively) efficientRuns on heavy fuel oil (cheaper But higher Sox, dust emissions)Space for 6th engineReady to use bio-fuels


Bonaire has potential for algae oil

• Yield = 25 – 100 ton/ha/yr (required is 10.000 ton/yr)

• Price = 50 – 100 euro/bbl (oil price is now 75 $/bbl)


Present situation

• System is supplying Bonaire since August 2010

• First experiences:

– Power plant is running stable

– Wind farm is performing well

– 1st year of operation will be for fine tuning PMS, battery system to optimize wind share

– Demand on Bonaire is growing fast so first extension is being planned

– In November 2010 we’ll present to Bonaire Utility WEB on the benefits of adding solar energy to the system


Lessons learned

• Grid study is essential:

– Dynamic system behavior at various scenarios

– Demonstrated the need for the battery

• Mismatch in requirements permitting procedures

• Complicating factors:

– Contracting was at all-time high in the market (high EPC prices, weak dollar)

– Econcern (our mother company) went bankrupt

– Bonaire was / is going through a political transition phase


Show-case for the region

• First WD-project of this scale (25 MW)

• 40-45% renewable from day 1

• 100% renewable is possible

Suitable for many islands

in the world

The solution to maximise

the wind share without

high extra costs

Project was noticed in the US: http://www.edinenergy.org/bonaire.html


We can do a lot back home!

• Check out the options DC offers:

– The new DC Climate plan

– The arriving DC Green Utility

– Solar PV support plan for residents

– Energy Efficiency support for residents

– IMBY, an on-line NREL tool that helps to assess your personal business case

• Depending on what your influence is:

– Smaller things like replacing light bulbs at home do matter!

– Bigger things like choosing for Green Buildings make good business sense.
