Risk Management Tools
Most countries manage their SoS combining : Network sizing based on long term
planning Storage Diversification of supplies Interruptible contracts and virtual
storage Booking of additional transportation
capacities. Fewer countries (can) rely presently on:
Utilisation of LNG terminals Excess of production capacity Purchase on the Spot Market Buy back mechanisms of firm capacity

Non firm supply contracts : market survey in Belgium in
2001Supply contracts in 2000 (% of industrial customers) :
52% non firm21% firm27% firm and non firm
For non firm supply contracts :76% the supplier has the right to interrupt24% the customer has the right to interrupt
Why do customers choose a non firm supply contract :
62% ‘bi-fuel’ equipment this investment is in 56% of the cases not only made for hedging against the interruption risk but also for arbitrage

Non firm supply contracts : market survey in Belgium in
2001Modal frequency of interruptions:
once per yearNotice (modal period) :
1/3rd 1 hour1/3rd 1 day1/3rd 1 week
Price reduction compared to firm supply :the price reduction required by the ‘modal’ customer is lower than 25%.

Fixing security of supply ( SoS) levels in an open
market Collective level of SoS
=
sum of individual levels of SoS + corrective PSO (e.g. PSOs for PLR services)
Individual level of SoS = PSO (e.g. 1 in 20)
Individual level of SoS = negotiated
households large consumers

Top-up
In a liberalized market there is a real risk that suppliers take a chance on weather conditions and do not book enough storage.
“Top-up” refers to public service obligations guaranteeing that enough physical storage capacity and/or gas in storage will be available.

Top-upComplex system : monitoring both the available infrastructure and the
inventory levels throughout the year calculation of the amount of top-up storage: taking into
account the benefits of virtual storage, the legitimate trade-off between additional transport capacity and storage, etc
who is in charge of top-up storage: centralizing the responsibility in one supplier of last resort (TSO, storage operator or a specific body?) or imposing a level of storage to every supplier or combining both methods ;
targeting the costs: the costs incurred by the centralized body should be covered by a legal fund, preferably fed by those who are responsible for a lack of storage.

Financing new infrastructure
World Energy Investment Outlook 2003, published by IEA: to be taken with caveats!
distinguish regulated business (network activity) from competitive activities (production)
in regulated business: fundamental difference between cost-plus tariffs and price-cap regulation
in production: no need for industry-specific incentives for investment, besides the acceptance of long term take-or-pay contracts
