  1. Waste heat water heated greenhouses Using hot water from Kakanj coal power plant to heat greenhouses for off season vegetable production

  2. Idea is not new • Niederau, Germany, from 1987 • ROCA 3, Netherlands • Many other in development • Numerous studies Edin Pašić, Waste heat water heated greenhouses

  3. Major competitive advantages • Heating is 28% of total costs in heated greenhouses. • It can be obtained virtually for free from waste water tanks in the power plant. • Location is within 20 minutes from two largest cities in BiH (Sarajevo and Zenica) with aprox. 1 million potential consumers. Edin Pašić, Waste heat water heated greenhouses

  4. Business opportunities • Bosnia imports 25 million EUR of off season vegetables per year (very conservative estimation) • No large scale off season producers in Bosnia • Government subsidies up to 50.000 EUR for greenhouse building • Business expansion (hydrophonics, volume expansion...) Edin Pašić, Waste heat water heated greenhouses

  5. Investment • 6 ha arable land • 5 ha greenhouse • Hot water pipeline and heat exchangers • Office and warehouse: 1000 m2 Edin Pašić, Waste heat water heated greenhouses

  6. Possible location within 500m • Power Plant • Greenhouse location Edin Pašić, Waste heat water heated greenhouses

  7. Basic metrics • Initial investment: 1.500.000 EUR • Net income/year: 270.000 EUR • 10 year IRR: 12% with no subsidies included • 30 years NPV at 8% discount rate: 1.5 million Edin Pašić, Waste heat water heated greenhouses

  8. Basic metrics • All calculations are based on single crop production (tomato) • Netherland standard cost structure of 64% is used in calculation. Edin Pašić, Waste heat water heated greenhouses
