LCOE values

[xavier]

I am interested in getting the LCOE values as opposed to the marginal electricity prices for my five scenarios. I have activated the levelised costs function in the case manager but I do not know how to activate it in VEDA-BE, and in case it is already active, I don't know which variable in the results represent it. 

Further, I ran an RPS scenario with 100% renewable constraint in 2050, but no storage. I realised that in all the timeslices except the night, the transmission marginal electricity prices are zero or negative in 2050. My assumption is that the zeros and negative values indicate that it is ecconomically infeasible (unprofitable) to generate electricity in those time slices. I am not sure if this is the right intepretation? 

Any guidance will be appreciated.

Thanks, Akanudia. I just got it running.
