Lately when the price in the day-ahead market is negative we shut-down our parks, with which type of PPA do we benefit the most?
Pay-as-produced
Baseload
Being fully merchant
With a purely mercedes model
Match park with off-taker
(Arla, Google, Toms)
(Ebberup, Hoby, Næstved)
Næstved-Google, Ebberup-Arla, Hoby-Toms

Næstved-Arla, Ebberup-Toms, Hoby-Google
What are the main risks, if any, associated with a Baseload PPA and which one is shared with a Pay-as-produced?
Profile risk - No risk shared
Capture risk – Capture risk is shared
Profile and capture risk – both shared
Profile and capture risk – no risk shared
When is the CSRD (Corporate Sustainability Reporting Directive) expected to be effective in DK from
on reporting from 2024
on reporting from 2025
on reporting from 2026
on reporting from 2027
What are the main risks associated with a monthly baseload (BLM) compared to baseload annual (BLA) and which one is shared?
Profile risk - No risk shared
Profile and capture risk – profile shared
Capture risk – capture shared
Viggo mitigates all of them 😊
Which of the following statement is true for a 1MW / 2MWh battery
Can discharge at 1MW for 2 hours
Can discharge at 2 MW for 1 hour
It is ideal for ancillary services
None
Highest PPA price signed ? (also volume and type)
1500 DKK/MWh – 1,72 GWh/y – BLA
1000 DKK/MWh – 0,5 GWh/y – PAP
2000 DKK/MWh – 4,53 GWh/y – BLA
Just 550 DKK/MWh - PPA team CMON!
Who is financially responsible for imbalances and deviations between planned and actual energy production?
BRP, Energinet
BRP, Producer
BRP is solely responsible
BRP is solely responsible, but gets partially remunerated by Energinet
Given the same solar generation profile, in which of the two bidding zones will the PV capture in (%) be higher and what characteristics will it have (positive i.e. >100% or negative i.e. <100%)?
DK1 – above 100%
DK2 – above 100%
DK1 – below 100%
DK2 – below 100%
In 2022 in Denmark, when were we more likely to experience negative (below 100%) and positive (above 100%) PV capture?
Always positive
Negative – winter, Positive - summer
Positive – winter, Negative – summer
Always negative
Can EVs contribute to consumption flexibility?
No, they don’t have a significant energy consumption
Maybe, but there will never be enough EVs
Yes, only if they charge during the day
Yes, if they time it correctly
Which of these measures is NOT likely to help improve PV capture?
