You trade power??So you are to blame for the fact every year I get tapped up for ~30delta Dutch power term APO puts and they never pay up! ;)
This brings back memories!
I once did a project for the Dutch ministry of economics affairs, value exotic options embedded in renewable energy subsidies they handed out.
First, the contract was horrible, it took 3 months to get an agreement, maybe 10 versions.
Then years #2 they again had to price those options and asked me to update outlooks of markets, recalibrate the model and write a new 20 page report. They were willing to pay me 1 day. But since it was kind of important to not make any mistakes (both contractual and reputation wise) and also a lot of work it took me a week. They still paid me me just 1 day and I told them to find someone else next year.
Year #3 they asked me to instruct people from a government research organization so that they can do it. As it turns out the guy who I had to hand it over to was a former PhD student of mine. He told me they were charging the ministry *a 100 days* for the update!
All in all it wasn't a positive experience, left me with a bad taste.
And I learned my lessons, like Paul said, sometime when thing are complicated from the start then that's a strong indicator that things will continue like that, and then you should walk away.
I think it's very likely that they won't include you in the commercialization process and that you will feel bad. Maybe you should build it yourself in your own time, keep the IP, and make them a partner instead of the other way around (and try to get that agrrement before you start to build it,... Hmm more paper work..)
Giving away power puts is fine, it's the calls you have to worry about! This was a long time ago. Dutch subsidies cause a lot of troubles: I remember the time that chopping up large amounts of forests in Scandinavia and shipping it to The Netherlands was considered environmental friendly biomass, and eligible for subsidies.
