Abstract
Mazkur maqolada sanoat korxonalarida energiya tejamkor texnologiyalarni joriy etishning iqtisodiy samaradorligini baholashning nazariy, uslubiy va amaliy jihatlari tadqiq etilgan. Sanoat ishlab chiqarishida elektr energiyasi, tabiiy gaz, issiqlik energiyasi, siqilgan havo va boshqa yoqilg‘i-energetika resurslaridan foydalanish xarajatlari mahsulot tannarxining muhim tarkibiy qismlaridan biri ekanligi asoslangan. Energiya samaradorligini oshirish faqat energiya sarfini kamaytirish vositasi sifatida emas, balki ishlab chiqarish xarajatlarini optimallashtirish, mehnat unumdorligini oshirish, texnologik uskunalarning ishonchliligini yaxshilash, mahsulot sifatini barqarorlashtirish, ekologik to‘lovlar va avariya xavfini kamaytirish hamda korxonaning bozor raqobatbardoshligini mustahkamlashga xizmat qiluvchi kompleks investitsiya yo‘nalishi sifatida ko‘rib chiqilgan. Tadqiqotda tizimli tahlil, qiyosiy tahlil, energiya balansi, investitsion tahlil, diskontlangan pul oqimlari, sezgirlik tahlili va hisobiy modellashtirish usullaridan foydalanilgan. Shartli o‘rta quvvatli sanoat korxonasi misolida yuqori samarali elektr dvigatellari va chastota o‘zgartirgichlar, siqilgan havo tizimini optimallashtirish, ikkilamchi issiqlikdan foydalanish, qozonxona va bug‘-kondensat tizimini modernizatsiya qilish, energiya tejamkor yoritish hamda avtomatlashtirilgan energiya monitoringi tizimini joriy etishdan iborat investitsiya paketi shakllantirilgan. Hisob-kitoblar natijasida umumiy investitsiya miqdori 10,8 mlrd so‘m, yillik sof iqtisodiy samara 3,668 mlrd so‘m, oddiy qoplash muddati 2,94 yil, diskontlangan qoplash muddati 4,58 yil, sof joriy qiymat 3,306 mlrd so‘m, ichki rentabellik me’yori 28,17 foiz va investitsiyalar rentabellik indeksi 1,306 birlikni tashkil etishi aniqlangan. Sezgirlik tahlili energiya tejalishidan olinadigan yillik naf 20 foizga kamaygan taqdirda ham loyiha sof joriy qiymatining musbat bo‘lib qolishini ko‘rsatgan. Tadqiqot natijalari sanoat korxonalarida energiya tejamkor loyihalarni tanlashda faqat oddiy qoplash muddatiga emas, balki loyihaning butun hayotiy sikli davomida shakllanadigan energiyaviy, iqtisodiy, ishlab chiqarish va tashkiliy samaralarni birgalikda hisobga olish zarurligini ko‘rsatadi.References
