The New Zealand Gas Market - an Overview Presentation to the NZ Petroleum Conference March 2004
Today’s talk • Industry’s key challenge • Supply and demand outlook • What is at stake for gas industry • Customer implications • Petrochemicals • Power generation • Industrial • Residential & commercial • Possible solutions • Conclusions

Suppliers and customers both lose from uncertainty • Vicious circle can develop: • limited upstream investment creates supply uncertainty • downstream users switch away from gas due to supply uncertainty • dwindling market opportunity limits upstream investment Supply uncertainty Demand uncertainty
Entire industry has large direct stake in the outcome Indicative estimate ? ?
Petrochemical sector • Petrochemical sector was 42% of usage in 2002 - large demand source has been important: • baseload revenue can anchor new developments • some ability to swing (due to traded nature of final product) • But: • final product prices can be very volatile • NZ has moved from being a low cost producer to being a relatively high cost producer • NZ capacity is being replaced/displaced by new low cost capacity in Chile and Trinidad (source : Methanex) • Likely that NZ will become marginal producer, dependent on local gas price and world prices for product • Until it is retired, sunk cost plant could provide a market for a future large gas discovery
Power generation sector • Power generation accounted for 33% of usage in 2002 • Gas fired plant has been fastest growing source of new generation - 15% p.a., compared with 2.5% p.a. for all generation • Gas also plays an important role as a swing fuel to meet seasonal and inter-year variations
Power generation - future investment • Gas is still a good option for new electricity generation but needs to be price competitive • Carbon charge has major impact on relative costs of different generation sources Sources : Infratil Update - September 2003
Power generation - flexibility requirements Budgeted Gas Use for Thermal Generation PJ/month Some flexibility is important :- • Contracts with rigid “take” obligations at times of high hydro flows are costly to generators and could result in gas being burned while hydro spills
Industrial sector • Industrial usage accounted for 10% of demand in 2002 • For many industrial customers the economics of gas usage are now becoming marginal *Contact Energy estimates for typical Hawkes Bay customer
Industrial sector - future trends • Industrial market requires:- • assurance about future fuel supplies for future investment • competitive pricing compared to other fuels • some flexibility of take in contracts • There are already signs that some industrials are weighing up price and security of supply issues and contemplating a move away from gas eg Fonterra announcement about building a coal fired energy centre at Whareroa.
Residential sector • Total of 220,000 customers • Using over 6PJ of gas per year • Large number of retailers given number of customers *As detailed in Wanganui Gas, Genesis and Contact latest annual reports
Residential sector - untapped potential • Limited penetration, large number of houses on streets that contain gas mains though not connected to gas • Economics should favour gas for water and space heating due to thermal efficiency gains
Residential sector - why such limited penetration? • Connection process is not customer friendly • no defined service for time to connect (can wait 3 months) • no defined price • Historically appliances have been expensive • Limited marketing • Retailers have little incentive to connect new customers; low margins and customers can switch • Network companies appear more interested in returns from existing customers than investing in growth • Poor economics for customer • Gas no longer provides significant cost savings over electricity, especially given the high cost for connection. • LPG solutions are increasingly competing against reticulated gas • Residential sector has unrealised potential but it will require changes to access full growth
Future effort • Upstream • ensure existing sources of gas are brought to market swiftly • provide flexibility where customers value it • Pipelines • consider present revenue vs future revenue tradeoffs • ensure least cost operation • Power generation • provide revenue underpinning to encourage development of new gas sources • be prepared with alternative fuel sources where appropriate
Future effort • Industrial sector • clearly define the value/reliability requirements • forward contract where possible to manage risk and underpin development • Residential sector • be aware that long term gas supply for this sector has very high level of assurance • Policy makers • remove impediments to new development (e.g. carbon tax uncertainty) • foster upstream competition (e.g. open access regime for transmission)
Conclusions • NZ has a large market for gas provided it is priced competitively • Continued presence of Methanex ensures that there is always a ready outlet for a large gas discovery • Electricity generation will continue to offer an attractive market for gas but some flexibility in contract terms is required • Networks will need to reconsider pricing issues if residential market is to reach full potential • Industrial market is likely to be relatively fragile and will be focussed on security of supply and price issues
