Valuing European LNG regas capacity
European regas capacity is back & flashing on the commercial radar screen. The obvious explanation for this is a jump in terminal utilisation over the last 12 months as Europe absorbs surplus LNG.
There are however other structural drivers behind a renewed interest in regas capacity. Liquid hub access is becoming more important as a means for portfolio players to optimise & hedge increasingly complex LNG portfolios. At the same time cargo diversion flexibility is increasing, supported by a wave of new US export capacity coming online across 2019-21.
This renewed focus on regas has been reflected in our client work across the last year. We have been engaged by several LNG portfolio players to analyse the valuation of regas capacity & its portfolio impact. We have also been engaged by terminal owners to look at valuation from a capacity monetisation perspective.
As a result of this work we have developed a framework for regas capacity valuation which we summarise in today’s article. We focus on NW Europe regas with liquid hub access (e.g. UK, NL, FR, BE, DE), but the principles apply more broadly to less liquid access points.

Regas value 101
Regas capacity is an option to regasify an LNG cargo and deliver it into a liquid hub.
Take a simple example of a LNG portfolio that owns a NWE LNG spot cargo off the coast of NW Europe. In the absence of regas capacity access, this cargo can only be monetised via sale of the spot cargo (at a relatively illiquid NWE spot price). If the cargo owner has regas capacity, the cargo can alternatively be monetised at a liquid hub (TTF or NBP).
If you want to get technical, regas capacity is essentially a strip of options on the spread between TTF and NWE LNG spot prices.
Regas capacity does not just support the monetisation of spot cargoes, but also the hedging of forward exposures. Take a US export supply contract as an example. This represents a strip of forward cargo exposures with diversion flexibility (e.g. to Europe or Asia). Regas capacity access allows these exposures to be hedged on a forward basis against the liquid TTF (or NBP) forward curve and then optimised or re-hedged over time against the less liquid JKM curve.
4 building blocks of regas value
In order to value regas capacity it is useful to deconstruct value into components. Diagram 1 summarises four building blocks of value.

1.Merchant slot value
First we consider the merchant or standalone value of regas capacity, in the absence of any other portfolio components. Merchant slot value is currently limited by the fact that there are no structural constraints around NW European regas capacity access. Across UK, Netherlands, France & Belgium there are plenty of spare regas slots under normal market conditions.
Merchant slot value is a function of the expected probability of slot utilisation multiped by the price (or value) of regas capacity when it is utilised. For regulated terminals this price is the regulated tariff. For TPA exempt terminals, regas slot pricing is also driven by regulated tariff levels as these represent the opportunity cost of alternative terminal access (in the absence of any NW European regas constraints).
Temporary regas capacity constraints can occur. For example, supply outages caused some UK regas capacity constraints in 2018 (during the ‘beast from the east’ cold weather pattern). High import volumes have also seen GATE constrained during periods in 2019. These constraints can cause merchant slot value to rise above regulated tariff levels. However limited secondary trading of regas slots, means this incremental value typically accrues to LNG portfolios with the flexibility to bring FOB cargoes into constrained terminals (see 2. Portfolio slot value below).
Over the next decade, the volume growth of flexible LNG is set to substantially outstrip planned investment in new European regas capacity. That means the probability of European regas constraints is likely to rise as (i) terminal utilisation increases with import volumes and (ii) regas capacity headroom declines. This structural tightening is an important driver of recovery in regas capacity value in the 2020s.
2.Portfolio slot value
The primary driver of a company’s willingness to pay for regas slots is the incremental value that regas creates when added to an LNG portfolio. Regas capacity can add optionality (e.g. facilitating diversion) or unlock constraints (e.g. access to liquid hub prices). These sources of value can be substantial given the limited liquidity & complex supply chain logistics of the LNG market.
Lets consider a practical example of portfolio value. A number of Asian buyers have US export contract volumes (e.g. JERA, Osaka Gas, GAIL, Sumitomo). These companies place significant portfolio value on physical access to TTF or NBP liquidity. This value is driven by the ability to manage supply contract risk and mark to market forward cargo exposures against a liquid curve. But it also allows value creation from forward hedging of diversion flexibility based on fluctuations in TTF vs JKM price spreads.
The challenge in quantifying portfolio value is that it is heavily dependent on the bespoke components of an individual portfolio. There is added complexity as to whether the value created by adding regas actually accrues to the regas slots or to other existing components of the portfolio e.g. flexible supply contracts.
However one thing is clear. A portfolio modelling capability is required to effectively quantify the incremental value of adding regas capacity. This capability allows the analysis of the interaction between evolution of pricing dynamics and portfolio exposures. We provide a simple illustration in the blue box below.
- Send out optimisation value
Value can be created by optimising the profile of send out from tanks at regas terminals against market prices. Send-out is effectively a single direction storage option (with no injection rights) and can be valued as such with stochastic storage modelling techniques.
However there are practical limitations on the value of send out optionality. It is typically limited by operational constraints e.g. requirement to retain inventory to keep tanks cool during periods of low utilisation or to empty tanks quickly to free up capacity for incoming cargos during periods of high utilisation.
It is not so often that tanks are in ‘sweet spot’ inventory levels e.g. 40-60%, and the value of holding high levels of inventory is also usually eroded by boil off gas (BOG) losses. Terminals with the capability to re-liquify BOG can have higher send-out value as this removes the requirement to manage low inventory levels and loss of BOG.
Some terminals have the capability to reload cargoes. This can allow capacity holders to circumvent destination clause restrictions in supply contracts. It can also create value via alleviating logistics constraints e.g. the reload of cargoes from Yamal icebreakers at NW European terminals allows more efficient deployment of these vessels on artic routes.
Both these sources of value are driven by contractual or logistical dynamics within specific portfolios. This again points to a LNG portfolio model to effectively value reload optionality.
Enabling reload in regas terminals typically involves low capex. There are also relatively low barriers to entry. These factors effectively cap the amount of value that can be assigned to reload optionality in the longer term.
Pulling component values together
Regas slots suffer from a lack of price transparency, given there is no liquid secondary market for capacity. The valuation of regas capacity is further complicated by the fact that it needs to be quantified as part of a company’s broader portfolio strategy. The value that slots create for an Asian buyer may be very different in size and nature to that for a commodity trader.
However the analytical approach to valuing regas capacity is becoming more consistent. And this focuses on using a portfolio valuation modelling framework to practically analyse how regas slots create value via adding portfolio optionality and unlocking constraints.
