UK Gas Supply/Demand Outlook UK/Ireland Gas Supply/ Demand 16 Demand 14 Billion Cubic Feet per day 12 ~7 10 ~10 8 6 4 UK Production+ Discoveries 2 0 2000 2005 2010 2015 • UK : supply gap opened in 2005 as production declines – Demand growth expected to slow to 2-3%/year to 2010, then levels off – First Qatar LNG imports available starting in Winter 2007/08

Project Scope Gas LNG LNG Gas to Pipeline Gas Gas Treating & LNG LNG Production Liquefaction Shipping Regasification $ 13 billion dollar mega-project employing full value chain integration, step-out technologies, and economies of scale to offset distance to market. • Gas from world’s largest gas field; 2.8 billion cubic feet per day • Two 7.8 million MTA trains will be the largest ever constructed; 60% larger than any to date • A fleet of 14 large LNG ships; at 210 – 265 km3, 70% larger than any ever built • Receiving terminal in the U.K. to re-gasify and deliver 2.1 billion cubic feet per day - 15- 20% of UK demand

South Hook Terminal Development Plan Description • Upgrade and refurbishment of existing jetty • Five 155 km 3 full containment LNG storage tanks • Two berths • Submerged Combustion Vaporizers (SCVs) • 2.1 BDFD export • Pipeline extension ( ∼ 128 km) to national gas grid to be built and operated by others (NGG) • PL grid reinforcement by NGG • EPC by Chicago Bridge & Iron • Total capex of $1.4 B spent over 2003 – 2009 • Status • Phase 1 currently 65% complete; Phase II 40% complete • First gas early 2008

The Environment & South Hook LNG: Jetty Gas Pipeline • Maximise use of existing structure to minimise impact on marine environment • Close consultation with DEFRA, EA, CCW, MHPA on management of redundant structures • Careful management of jack-up rig/anchor positioning to minimise impact on eel grass, red maerl • Highly efficient new-build ships to be deployed • Efforts to minimise impact on public use of coastal path, small boat passage

The Environment & South Hook LNG – Tanks Gas • Full containment (tank within a tank) structure for maximum integrity • Gas kept liquid through effective insulation; no refrigeration requirement • 2 million tonnes spoil moved; screening bunds created • minimise visual intrusiveness of facility • Tanks, though large, were specifically designed to be wider and squatter than normal to minimise visual impact

The Environment & South Hook LNG – Vapourisers Gas • Two competing technologies: open rack, submerged combustion • Open rack • Use large quantities of sea-water; impact on marine organisms • Pumps/lines require anti-foulants • Return water significantly colder • Submerged combustion • Small quantities of LNG boiled off • Used to heat water bath; some CO2 emissions; very high efficiency (98%) • Technology choice made in conjunction with key stakeholders • Designed to minimise impact of emissions from vapourisers

The Environment & South Hook LNG – Water Management Pipeline • Topography of site presents water drainage challenges • Exacerbated by soil disturbance during construction • Complex system of hold up ponds developed • Existing settlement pond by-passed • ‘Silt Buster’ installed • Regular monitoring of effluent quality; daily sampling, multiple visual inspections • Achieving 30 mg/litre sediment levels (c.f. permitted level of 75 mg/litre) • System proved robust even during recent heavy rains

The Environment & South Hook LNG – Conservation Area Gas to Pipeline • Unique eco-system • Legally binding Section 106 Agreement with PCC/PCNPA • 110 acres of site made over for nature conservation • Management plan under development • Steered by site manager + representatives from interest groups • Access to area will be controlled • Artificial badger sett created • Kestrel nesting boxes to be installed shortly

South Hook LNG – Community Gas Gas to Pipeline • Public consultation a key element of advocacy strategy • Visitor Centre • Website • Leaflets • Public/stakeholder meetings • Significant engagement with the Media • Rolled out Community Funding Initiative in 2006 • ‘shallow and wide’ strategy • Focus on education, health, environment • Not a substitute for public funding • Focus for 2007 is to develop more self-sustaining initiatives
