Economic analysis
Economic analysis in the SpeicherCampus context: needs real data and several benefit streams. Technically, the term is usually described as the assessment of costs, savings and benefits.
What does economic analysis mean?
A storage system’s economic analysis weighs investment and operating costs against earnings over the term. Its particularity: the earnings rarely come from one source — only the combination of self-consumption savings, demand-charge reduction, avoided curtailment and future options yields the true picture.
The calculation becomes credible only with real data: the 15-minute load profile, PV generation, grid fees and tariffs of the specific site. Blanket payback promises are not serious.
What matters in practice
- quantify every benefit stream separately, don’t hide them in one number
- count losses, degradation and maintenance as costs
- show sensitivities: vary electricity price, demand charge, PV yield
- no guaranteed payback periods — make assumptions transparent
Practical example
A project pays off across three pillars: 55 % of earnings from self-consumption, 30 % from peak shaving, 15 % from avoided curtailment. Each pillar alone would be too weak — the documented combination also convinced the financing bank.
The SpeicherCampus perspective
SpeicherCampus builds economic analyses from real site data and discloses every assumption — robust rather than impressive.
