1 · Effective €/kWh. Total installed cost per usable kWh, including augmentation assumptions — the only number that compares two tenders honestly.

2 · Cycle-life warranty substance. Cycles, years, throughput and state-of-health clauses — and which cap arrives first at your duty cycle.

3 · Availability guarantee. Percentage, measurement basis, liquidated damages — or the absence of all three.

4 · LTSA terms. Scope, response times, exclusions, price escalators, and who carries augmentation cost.

5 · Augmentation & end-of-life. Who pays for capacity top-up, and who owns the decommissioning liability.

6 · Grid & compliance. Documentation for your DSO, fire-safety positioning, and insurance-relevant siting terms.
