2. For on 8Q.MW SEGS plant, 40 technical ond operating personnel ore required plus 600 person-hours per week ore required for low-skill mirror washing and skilled system
maintenance.
3. The levelized energy costs (lE() vory depending on the assumptions used in the calculations. The low volue was token from Kearney, D. et al. lt is based on 1 990 dollars and
3[}year levelized costs, and colculoted on the basis of SEGS financing by private investor partnerships. Notional Renewob Energy lnboratory cakuted the LEC at $0.13.
4. This value is bosed on the SEGS VIII plant. The plant generates power 8.64 hours per doy, of which sor mdioffon provides 75% of annual output.
