Solar Energy Generating Systems
Solar Energy Generating Systems (SEGS) er verdens største anlæg for solenergi. SEGS består af ni solkraft- værker i Mojave-ørkenen i Californien, hvor solstrålingen er størst i USA. NextEra Energy Resources opererer og er delejer i kraftværkerne.[1]
- SEGS I–II (44 MW) ved Daggett, byggeår 1984 – 1985,
- SEGS III–VII (150 MW) ligger ved Kramer Junction, byggeår 1986 – 1988,
- SEGS VIII–IX (160 MW) ved Harper Lake, byggeår 1989 – 1990.
Anlægget har totalt 354 MW installeret kapasitet. Dette gør det til verdens største solenergianlæg.[1] Gennemsnitlig energieffekt for alle ni kraftværker ved SEGS er 75 MWe — en virkningsgrad på 21%. Desuden kan turbinerne udnyttes om natten ved afbrænding af naturgas.
NextEra hævder at solkraftværkerne betjener 232 500 husstande og erstatter 3800 tonn forurenning per år.[2]
