1 A Dream to Reality : Pakistan s first 100MW Solar Power Plant PRESENTATION BY KAZI ZULKADER SIDDIQUI CEO, EMERGING ENERGY SYSTEMS AND SENIOR ADVISOR, TBEA CHINA

2 Quaid-e-Azam Solar Park, Bahawalpur 100MWp Solar Power plant Solar panels as far as you can see

3 Presentation Dedicated to My buddy My classmate during Matric and Intermediate at Cadet College Petaro We passed out together in 1969 He was barely over 5 feet tall when he left Petaro

4 Brig. Dr. Nasim Akhtar Khan The Dreamer An unsung hero True pioneer of solar and alternate energy in Pakistan BE from NED in Electrical in 1974 MS in Energy Resources from Univ of Pittsburgh in 1983 PhD in Solar Energy from Colorado State University in 1992 Established solar lab at NUST EME College, Pindi in 1990s Built tons of prototypes. Tested even in Siachin Founding Secretary of AEDB in 2003 Vice Chancellor of Hamdard Univ where he established a dept of energy

5 How did it happen Full marks to Govt of Punjab for the initiative We presented concept paper to Chief Minister Punjab in May 2013 to set up 1000MW solar power plant Highest quality products Lowest possible price Fastest execution time (months not years) Financing available from China Tariff would compete with other technologies and bring the basket price downwards CM sent a professional team to China to study and evaluate MOU signed with TBEA to meet the promise Solar Park was established in Bahawalpur in Cholistan International tenders were called for first 100MW plant after due pre-qualification process in which 12 international companies were pre-qualified After competitive bidding, TBEA was awarded contract being the lowest qualified bidder and meeting requirements of due diligence

6 TBEA (company selected to build the plant) Largest Solar EPC company in the world During 2014, TBEA constructed over 1,500MW of solar power plants Largest manufacturer of transformers in the world, with capacity to build the largest size transformers to highest standards Largest manufacturer of cables in China One of the two largest manufacturers of inverters in China Own manufacturing of combiner boxes, solar panels Own processing of silicon from silica sand Own design institute for solar technologies Current annual sales of over $ 8 billion

7 6.12 kwh/kw/day average at tilted flat plate Bahawalpur Bahawalpur Quaid-e- Azam Solar Park Cholistan

8 Some key features of 100MW Plant 500 acres of land for 100MW (out of 10,000 acres allotted to Solar Park of which 6,500 acres being developed for 1000 MW) Infrastructure (access roads, boundary wall, water, transmission line, auxiliary power, security) provided by Govt of Punjab Land provided on lease of 25 years at $1 per acre per year Located around 10km from Bahawalpur airport Flat land generally with some dunes Solar Park will have eventual capacity of at least 1000MW. Remaining 900MW will be installed by IPPs Connected to grid at 132kV. Transmission line running through solar park

9 100MW Plant features Design, engineering, supply, construction, testing and commissioning done by TBEA Highest quality components (virtually the Rolls Royce of solar industry) Quality control and monitoring done from pre-manufacturing, during manufacturing, upon arrival at site and after energization 392,158 solar modules of 255W each Nearly 10,000 arrays 100 inverters of 1MW each 100 transformers of 33kV 1000 kva 2 transformers of 132kV 100 MVA 1400 combiner boxes Two German consultants for design control and two independent European testing agencies employed for tests All equipment meets and exceeds IEC and other international standards NTDC requirements and standards complied 140,000 screw piles Thousands of kilometers of cables Main building Switchgear building, SVC buildings, control building Substation Performance guarantees over 25 years DCS (monitoring system) and SCADA

10 Fast track to 100MW Project Timeline Jun 2014 contract signed Oct 2014 first equipment arrives at site Nov 2014 construction and installation starts at site Jan 2015 construction and installation completed (3 months) Feb 2015 testing and commissioning Mar 2015 expected grid connection EPC cost of $ million (exclusive of taxes) Total project cost estimated at $150 million

12 Combiner Box

13 33kV Transformer and Inverter 1MW

14 Beyond the Horizon. Nearly 400 acres utilized out of the 500

15 Each block is 1MW There are 100 blocks Structure uses screw piles. There are no concrete foundations

16 Angle and space is calculated to maximize power output and minimize shadows, and leave space for maintenance

32 Cost of Electricity Latest NEPRA Tariff (January 2015) North Region US cents to US cents South Region US cents to US cents Above rates are maximum, with downwards adjustments for savings based on Power produced in excess of capacity factor of 17.5% for North and 16.78% for South Construction Period Interest Plant Insurance Loan interest rates (KIBOR / LIBOR plus) Final rates paid to IPPs could be as low as 12 cents

33 Pakistan and issues for solar technology Manufacturing Solar panels (silica processing, ingots, wafers, cells, modules) Inverters Transformers / Switchgear, Substation Equipment Structure Cables, etc Standardization and Test Laboratories Systems design and engineering Development of companies in engineering, consulting, execution, O&M and other services R&D Manpower training / Capacity building

34 Issue Quality of Products We are a cost conscious nation Do not understand meaning of quality particularly in case of Solar Technologies Most of the products entering Pakistan market are junk with claims of 25 year life or even performance. How do you ensure? How do you recognize difference in quality? Case of top Chinese manufacturer with Economy Model (made for Pakistan, India and Sri Lanka only) Standard Model and International Standard Model Role of Government in ensuring quality

35 Some conclusive thoughts IPPs will be set up under NEPRA tariff regime Set up of standards for solar? Set up of standardization and testing laboratories to ensure quality and certification? Academics and R&D capacity building Explore natural resources for raw materials Find investors who will invest into processing and manufacturing on large scale to produce quality and quantity Develop consulting houses and engineering companies for design and execution Examine how we can compete internationally without subsidies Move away from off-grid systems to on-grid systems for homes and commercial applications with net metering
