1 Finding Reliable Power Supply for the Erongo Region
Arandis Investment Conference PI Shilamba MD: NamPower 4 November 2011

2 Supply and Demand in Namibia Challenges Update on Projects
Content Supply and Demand in Namibia Challenges Update on Projects Successfully Concluded Under Construction In Feasibility NamPower’s focus

3 Supply & Demand Situation
Installed generation capacity of 414 MW (Including Anixas) increase with 92 MW by March 2012 (Ruacana Unit 4) Transmission Network connected to Botswana and RSA Zambia connected via Caprivi Link and providing alternative route to Zimbabwe, DRC and Mozambique Maximum Demand of 511 MW (incl. Skorpion 580 MW) – Jun 2011 Imports up to 80% of energy requirements in some periods Demand growth 2011 Energy (MWh) = 3.7% (forecast 2012 : 4.4%) Peak demand (MW) = 3.5% (forecast 2012 : 4.6%)

4 SAPP Trading Partners Utility Agreements Duration Capacity ESKOM
Supplementary Power Supply Agreement Year on year Varies according to requirements Bilateral PS Agreement 15 yrs (signed 2006) Varies according to availability EDM (Mozambique) Power Supply Agreement Renewable (non-firm) 40 MW ZESA (Zimbabwe) 5 years (commencing 2008) 150 MW (firm) ZESCO (Zambia) Power Purchase Agreement 10 years (signed 2009) 100 MW (50 MW firm) SNEL (DRC) (Head of Terms signed) 5 years (signed 2008) 50 MW To add an additional slide go to “insert”, “duplicate slide” 4


6 Challenges for the next 5-7 years
Same as SAPP Challenges General energy shortage High Demand growth & step loads Rural Electrification (New connections) Shortage of resources (HR and Financial) Struggle to agree electricity pricing path to reflect cost of new build requirements Little private investment into the Power Sector The process of ensuring security of supply has been getting steadily harder for several years, but it has not been obvious because NamPower has been effective in dealing with it up to now. Approaches used successfully to date must now be augmented by new activities

7 Short Term Critical Supply Project (STCS)
Any base load power station for commissioning only by 2015/2016 Power supply deficit of 80 MW as from the 2012 winter, increasing to 300 MW by 2015. Worsened by expiry of ZESA agreement in 2013 A dedicated team appointed to the project Solutions will include one or a combination of the following: New power purchase agreements with SAPP trading partners New renewable and PPA with renewable IPP’s Increased DSM programs Upgrading of existing plants PPA’s with other IPP (Arandis Power) Final project plan expected by Dec 2011

8 Critical to implement base load power plant
Capacity constraint due to absence of any new base-load plant A base-load power station is essential by January 2016 Not many indigenous large plant option available Guidelines: Energy White Paper => Serve 75% of energy and 100% peak All base-load plants have Forex components that need to be accounted for Electricity Tariffs Recent average tariffs increase of 18.28% Upcoming capital investment of up to N$14 billion over the next 4 to 5 years It is estimated that the cost of supply to NamPower in 2015/16 can double to N$1,00/kwh compared to the current levels of 45c/kwh Need for GRN, ECB and NamPower to agree on a smooth upward pricing path with the view to avoid future price shocks, especially when a base-load power station will be commissioned by 2016

9 Hwange, DSM, Caprivi Link, Anixas
Conceptualization: Nuclear, Municipal Waste, CSP F U N E L Investigation: Wave Energy P R O J E C T Feasibility: LOHEPS, Recycled fuel, Erongo Coal, Baynes, Kudu Gas, Wind, Solar PV, Zizabona, Biomass, Van Eck Rehabilitation Implementation: 4th Unit Ruacana Operation: Hwange, DSM, Caprivi Link, Anixas

10 Hwange Investment PPA (150 MW) effective as from 2008
A good example of regional cooperation Project declared “Power Deal of the Year“ Africa Investors: Infrastructure Investment Awards

11 Caprivi Link Interconnector
Second largest investment in Namibia (NAD 3,2 billion) Project completed below budget 300 MW transfer capacity: completed June 2010 with official commissioning on 12 November 2010 Opportunity to implement phase 2 (additional 300 MW) Africa Energy Award for “Best Fast Track Energy Project”

12 Anixas 22.5 MW Diesel Generators at Walvis Bay
Project cost N$ 375 million NAD 250 million grant from GRN NAD 125 million from NamPower balance sheet Additional land adjacent to Paratus to build Anixas and new Transmission Station Design Philosophy to allow for future extensions COD July 2011 Official inauguration 03 November 2011

13 4th Unit Ruacana Installation of a 4th unit at Ruacana Hydro Power Station Increase capacity with 92 MW Project Cost NAD 750 million Project Dates: Commencement date was 27 March 2009 Work on site commenced during July 2010 Commercial operation is expected first quarter of 2012

14 Erongo Coal Power Station
01/2008 Establishment of a coal fired power station in the Erongo region has been identified as part of NamPower’s Security of Supply plan NamPower seriously in consideration of this option as it can be fast tracked Medium sized capacity (150 to 300) MW) Modular development allowing phased developments up to 800 MW NamPower ESIA

15 Progress and timelines required
01/2008 Progress and timelines required Project definition to be confirmed by Jan 2012 EIA Scoping to be concluded and Technical concept confirmed (including environmental mitigation requirements) Coal options confirmed and Coal value chain optimised Land procurement started Water supply solution determined Indicative costing (+- 25%) of complete project (power station, transmission, other infrastructure) Indicative project schedule to implement complete project Ready to start Tender/procurement process – April 2012 Final investment decision - June 2012 With good governance support Commercial Operation possible by 2015 NamPower ESIA

16 Critical Considerations
Fast track options Clean Coal Technology selection to allow fuel flexibility Coal sourcing options and cost Coal handling capacity at Walvis Bay port Land Availability and timing to procure Water availability and supply options Proximity to existing infrastructure necessary to keep cost down Infrastructure (road, rail, transmission grid, water supply etc) Economic environment (incl. tourism and sustainable development plans of region/towns) Environmental issues such as protected areas and biodiversity NamPower 16

17 Environment and Site Selection
01/2008 ESEIA study completed in June 2009, now update of study required: Sites considered and evaluated through a comparative Multi Decision Making Criteria Model considering technical, biophysical and socio- economic issues: Close to Walvis behind Dune 7 North of Swakop Site East of Arandis Site West of Arandis Outcome of evaluation: Site East of Arandis ranked as most preferred NamPower ESIA

18 Other Generation Projects
