Khi Solar One (50 MW), located in South Africa, is Abengoa´s third commercial solar tower and its first outside of Spain. This plant represents important technological advances in efficiency as it uses higher temperatures during the generation process.

1. ABENGOA
Khi Solar One is a 50 MW utility-scale concentrating solar power (CSP) plant being built by Abengoa near the town of Upington in the Northern Cape Province.
Tower is 205 meters tall and uses more than 4,000 latest generation heliostats (ASUP 140), and covers 300 hectares.
Khi Solar One uses super-heated steam, dry cooling technology, and a two-hour steam storage system. Technological advances incorporated in the design of this plant will increase efficiency and availability, as well as, reduce water consumption when compared to previous tower plants.
This project is a partnership between Industrial Development Corporation (29 %), Black Economic Empowerment Program via the Khi Community Trust (20%) and Abengoa (51 %). The construction of this plant is creating a local supply chain that brings economic development to the region.
Khi Solar One will benefit the entire country by:
Making over 4 Billion ZAR direct and indirect investment.
3 Billion ZAR tax payable in 20 year period.
Creating a supply chain with 2.6 Billion ZAR in component and services, 45% local content.
Local jobs : 80 % South Africans, 50 % local communities.
Creating over 36 full-time, high-paying jobs for plant operation.
Providing clean, sustainable power for approximately 65,000 homes in South Africa.
Increasing South Africa’s electricity generation reliability by energy source diversification.

2. Project details
Plant size: 50 MW output.
Abengoa has a signed an agreement with ESKOM to purchase all electricity produced.
Solar field covers 300 hectares with approximately 4.000 latest generation heliostats (ASUP 140).
Heliostats reflect sunlight onto the receiver. This tecnology prevents 183,000 tons of CO2
Electricity is generated with conventional steam turbines.
Saturated steam storage will provide up to 2 hours of dispatchable energy to be used after sunset or if cloudy.
Approximately 1/3 of water consumption because of natural draft dry cooling versus other wet cooling system.
Operation is scheduled to begin in 2014.
