  23. First Hydro Company Reliability and availability • Mode changes per annum c.35,000 • Overall mode changes reliability c.99% • Overall technical availability c. 95%

  24. Plant focus • Safety first (no compromise) • Operate and maintain plant to achieve competitive flexibility and reliability • working expertise in Electrical, C&I, Mechanical, Civil and IT • experienced, broad based and flexible teams • balance of quality in-house maintenance and specialist contract work • Close working relationship between Plant and Commercial Teams • Shift Trading and plant control room • daily and weekly operational strategy • long term operational and maintenance programme

  25. Commercial overviewDavid Alcock, TradingKevin Dibble, Marketing

  26. Commercial efficiency • Buy electricity overnight - pump water to top reservoir • Release water to generate at times of peak price Marchlyn Pumping Generation Peris Export ~.75 MWh Import 1 MWh • Overall cycle efficiency approximately 75% • Additional costs include transmission losses and Balancing System charges

  27. Markets • First Hydro operates in three markets • Has competitive advantage • Proportion of revenues from each market changes year on year Market Competitive Advantage Ancillary Services Frequency response and fast reserve capabilities Plant Reliability Balancing Mechanism Premium dynamics Trading Ability to deliver almost any contract shape and despatch plant right up to gate closure

  28. Maximising asset value People • Solid understanding of physical market drivers (real-time and long term) • Strong commercial and plant integration Systems • Robust trading and despatch systems • Customised real time information and decision support systems Processes • Strong focus on understanding and managing business opportunities • Traders discretion on price/product • strict risk management limits • daily (half-hourly) benchmarking of trading performance

  29. Capacity allocation • Capacity/energy allocated according to value 2,088 MW10.5GWh/day Ancillary Services Balancing Mechanism Trading

  30. Ancillary services overview • Physical services to facilitate system security and power quality • wholesale markets operate on half-hourly basis • ancillary services enable system balancing on a second-by-second basis • Procured by National Grid Company (NGC) • GB System Operator • NGC obliged to operate the system in an ‘efficient, economic and co-ordinated’ manner • costs managed via a regulated annual incentive scheme

  31. Forward procurement options Standing Reserve (20 mins. notice) annual or seasonal tender hydro, OCGT, demand-side approximately 2000 MW procured annually Fast Reserve (2 mins. notice) monthly tender, few eligible providers, small volumes Short term procurement Inherent level of reserve delivered by the market Residual reserve purchased by NGC via the Balancing Mechanism Require ~3500 MW of reserve in total Key ancillary servicesReserve MW Source: NGC

  32. Key ancillary servicesFrequency response • NGC manage system frequency in line with statutory obligations (within 1% of 50Hz) and operational requirements • Dynamic Frequency Response • units operate at part-load with output varying in response to frequency deviations - provides “second-by-second energy balancing” • basic level of capability is mandatory for all generators - utilised as required, mainly from steam plant • Static Frequency Response • automatically triggered by low frequency events - pumped storage, demand-side providers have capability • NGC currently forward contracts for enhanced services through negotiation

  33. Balancing Mechanism (BM) • Deals with residual energy balancing once traded markets have closed • Generators have sold half-hourly energy, and scheduled plant to meet contract position • System operator matches generation to actual demand by adjusting generation (or demand) via offers or bids in the BM • All parties required to bid into the BM, but due to flexible nature of assets, FHC is well-placed Example: BM offersrequired Scheduledenergy Required Demand

  34. Fast-acting plant in the BM System Demand and Fast Response BOAs Morning run-up • Gas/coal unit synchronisation risk • High rate of change of demand = greater risk Plant trip • Unpredictable events that require fast-acting plant held in reserve Evening TV pickups • Domestic load swings driven by TV events • Largely predictable • NGC able to plan using combination of fast and slow plant (25 May 2005) Fast Response BOAs Demand 45 GW 800 MW 700 MW 40 GW 600 MW 500 MW 35 GW 400 MW 300 MW 30 GW 200 MW 100 MW 25 GW 0 MW 20 GW -100 MW 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 Half-hourly Settlement Period BOAs = Bid-Offer Acceptances

  37. Wholesale markets (trading) Trading considerations • Capacity and energy dedicated to ancillary services • Margin (net of pumping) available in traded markets • Probability of being used in balancing mechanism • Reservoir management Key advantages • Asset physical ability to deliver any shape close to real time • Experienced traders in APX/short term markets • Proprietary live market information and decision support tools • Systems facilitate trading up to gate closure

  47. UK recovery signals England & Wales Reserve Marginabove Peak Demand (2004-10) • Tightening reserve margin • 2.4 GW nuclear plant (Magnox) expected to retire before 2010 • limited new-build anticipated before 2010 • 2.6 GW interconnector links to Netherlands and Norway unlikely to proceed before 2010 • renewable growth largely from intermittent wind power - requirement for firm power during peaks • environmental legislation will restrict 10-12 GW non-FGD output • Increasing development and acquisition activity 25% Notional Target Reserve 20% ForecastReserve Margin 15% Notional New-Entrant Point 10% 5% 2004 2005 2006 2007 2008 2009 2010 Source – National Grid January 2005 Update. Forecast includes all generation projects under construction and all planned closures of generation.

  48. Spreads - recent history UK Historic BaseloadGas & Coal Spreads • Over the past 12 months, gas prices have increased on the back of rising oil price • current oil prices remain close to all time high • Coal prices (delivered ARA) have declined since Jan 05 from ~$80/t to ~$65/t • EU ETS commenced January 05 • CO2 credit prices have increased since Jan 05 • Baseload power prices increased end 04/early 05 driven by rising gas price and CO2 cost £/MWh 20 Coal Spread pre CO2 15 Gas Spreadpre-CO2 10 5 0 M J J A S O N D J F M A M 2004 2005

  49. UK market - forward view Forward Baseload Gas Spreads, • Forward spreads indicate recovery • gas prices are expected to decline • coal prices expected to remain steady • As environmental constraints tighten Rugeley will shift to a more peaking role • From Jan 2005, cost of emitting CO2 has been treated as an additional marginal cost: • will be offset by NAP allocation • market liquidity increasing • early clarity on Phase 2 allocations important £/MWh 14 Gas Spreads post-CO2, no allocation 12 Gas Spreads pre-CO2 10 8 6 4 2 0 2005 2006 2007 2008 Forward prices sourced from Argus

  50. Legislation EU Emissions Trading Scheme commenced Jan 05 CO2 credits trading at €20-€23/t in June 05 for Phase 1 Large Combustion Plant Directive (2008) reduces emissions of SOx, NOx and dust from coal/oil plant Targets for renewable generation EU policy to reduce long term dependence on fossil fuels current HMG target of 10% generation by 2010 under pressure IPR strategy Actively trade emissions to support plant operations and maximise asset value May 05 allocations imply load factors of 44% for Rugeley, 55% for Deeside, 64% for Saltend Rugeley final decision, likely December 2005 focus on low sulphur coals to maximise value under LCPD constraints Renewables biomass co-firing at Rugeley Environment - implications for IPR
