• Scalability

• Reduce cost

Typical Project

80 MW 40 x 2.0 MW Turbines 3 x 60m masts 1 x 80 m masts

ReGenerate

So you’ve got your data…

•60 m mast: $20-40k installed/tower •80 m mast : $80-100k installed/tower •Routine maintenance: $5-10k/year/tower •Corrective maintenance: $5-10k/year/tower •Communication: $1k/year/tower •60 m decommission: $ 5-10k •80 m decommission: $10-30k

Total tower costs over 5 years: ~$425k Cost per MW=$5.3k

You can go cheaper, but you have to be lucky or good.

ReGenerate

…but what it is worth?

• Data processing • $1-2k/tower/year

• Assessments • Informative

• Verification

• 1 / year?

• $5-30k per

• Total for project: ~$130k

• Cost/MW: $ 1.6k

Don’t collect it, if you can’t maintain and analyze it!

ReGenerate

It can be scaled down effectively…

• 80 MW: $555k • 4 masts • 5 years • 5 studies

• 20 MW: $139k • 2 masts • 2 years • 1 study

• 5 MW: $35k • 1 mast • 1 year • 1 study

Must spend every penny wisely.

ReGenerate

…but it rarely is.

• Lacking expertise

• Need solid planning

• No clear goals

• Scope creep

• No budget for ongoing costs

• Bad or no advice

• Penny wise and pound foolish

It is better to do a small thing well than a big thing poorly.

…somebody has to clean up

•Two options •Carefully decommission and stored •Cut it down •Difference is ~$5k

•How many 10 m masts can you get from a 60 m tower? •20 m? •30 m? •What modifications are necessary?

ReGenerate

Challenges remain

•Late to the party •Installers want to hold towers •Installation •Shipping •Economies of scale •Gov’t funds buying used equipment? •Need cooperation from manufacturer

Is desperate too strong?

Optimize early and often

Best times to optimize?

• Define project area

• Major milestones

• “Final” layout

• Now

Because optimization is so cheap compared to the potential value, ROI is always high.

ReGenerate

weaknesses

• Just a tool

• Only as good as data

• Butterfly effect

• Potential for overestimation

• Perfect can be the enemy of good

ReGenerate

Work in progress

• $/MWh

• Calculation vs. rule of thumb

• Early and often

• ROI

• Requires expertise

ReGenerate

What’s it worth?

• Improve project

• Lower Uncertainty

• Financing

• Comfort

• Is it worth it?
