Have Questions?
The most important answers before your first PPA.
How long does it take to sign a PPA through Otark?
From first inquiry to a negotiated term sheet in 2 weeks, to a signed PPA in as little as 3 weeks. The industry average is 6 to 12 months. Your own time investment: max 8 hours, everything else runs through the platform and our experts.
What does Otark cost buyers?
Nothing. The PPA Marketplace is free for buyers: registration, publishing your demand, and comparing offers are all included. You take no financial risk by looking at your options.
Do we need PPA experience?
No. Otark guides you through every step, from load profile analysis and tendering to signing. On request, Otark connects you with specialized energy lawyers. L'Osteria, for example, went from zero PPA experience to a signed contract in under 3 months, covering 30%+ of its consumption.
What minimum volume do we need?
Far less than the traditional market demands: 1-Click PPAs start at 0.5 MW, while the traditional market typically requires 10+ MW. Individual PPAs via the marketplace are sized together with you, based on your load profile.
How does the power physically reach us?
Through your existing or a new energy supplier: the PPA volumes are integrated directly into your power delivery (sleeving). Physical delivery, balancing, and schedule management run through the partners and Otark, so you do not need your own energy trading desk.
How are sellers vetted?
Every seller on the marketplace is pre-qualified before you ever see an offer. You compare offers exclusively from 200+ vetted project developers and energy companies, including names like RWE, Statkraft, and TotalEnergies.
Does our consumption data stay confidential?
Yes. Your load profiles and tender details are treated strictly confidentially and GDPR-compliant. On request, we sign an NDA upfront, digitally, in 2 minutes.
Do we have to cover our entire demand with a PPA?
No. You decide the coverage yourself. Many companies start with part of their consumption: L'Osteria, for example, covers 30%+ via PPAs and sources the rest through its existing supply contract, gaining price security without losing flexibility.
