  3. 2a. Planning – wind conditions • Estimation of wind conditions: WAsP wind site assessment oder measurement? • Period of measurement: 1, 2 or 3 years – what expects the financing institut? • Measurement - crucial points: vertical wind profil correlation with suitable long term annual datas • ·Initial estimates of installed capacity and energy yield ADVISING DEVELOPING OPERATING hb@generalwind.com

  16. 2a. Financing of wind energy projects in Germany • -30 % equity; 70 % public loans by governmental KfW at 5%, to be payed back within a 10 – 15 years period of time • -due dilligance on all necessary documents: (land rental contracts, 2 – 3 independent wind data studies, investment contracts, building and operating permission, power purchase agreement PPA on >10 years, insurance and operation/maintenance contracts, dismantling provisions, …) • -financing contract to be signed with competiting private bancs, which have to secure (margins …) and administrate the KfW - loan ADVISING DEVELOPING OPERATING hb@generalwind.com
