Regulated and merchant interconnectors in Australia: SNI and Murraylink revisited
This paper examines the history of the various actual and proposed interconnectors between New South Wales and Victoria into South Australia. It covers the period from the earliest proposal for a regulated interconnector to the recent Victoria Supreme Court review and the latest ministerial proposals. It finds, inter alia, that the Supreme Court decision is likely to have strengthened, in a beneficial way, the regulatory regime for dealing with merchant interconnectors and the obligations on incumbent transmission companies. It finds that none of the proposals for regulated interconnectors did or would have passed the regulatory tests as formulated in terms of aggregate benefits to all market participants. It finds that neither of the merchant interconnectors (into South Australia and Queensland) are likely to have been profitable. It sees a possible explanation for the construction of regulated interconnectors in terms of the benefits to customers, or in terms of bringing about a single competitive market. Above all, it illustrates the political context in which decisions on interconnectors have been made, and the need to take account of such motivations when comparing the likely effects of regulated interconnectors versus merchant interconnectorsmerchant investment, interconnectors, electricity, regulation, transmission
Regulatory Uncertainty and Inefficiency for the Development of Merchant Lines in Europe
This paper evaluates regulatory uncertainty and inefficiency that may prevent merchant transmission investors from committing in Europe, in particular when they are dominant generators. We argue that market players may perceive regulatory uncertainty to acquire exemption on merchant line mainly because of the discretion given for the application of Art. 7 of the Regulation 1228/2003 on cross-border exchanges. However we show that an emerging strategy of the European Commission for granting exemption on merchant transmission line can be eventually derived from recent legal and regulatory proceedings. It mainly consists in relying on TSOs to build merchant lines. We demonstrate that this strategy is neither a first best nor a second best given imperfect unbundling and the current flows in the allocation of regulatory powers. Indeed, it prevents merchant line investment by dominant generators with low generation cost while they have currently more incentive than TSOs to build merchant lines. Since unregulated merchant transmission investment by generators would be problematic, we show eventually that the current strategy of the application of Regulation can easily be fine-tuned to reach this second-best optimum.Regulatory Uncertainty and Inefficiency for the Development of Merchant Lines in Europe

Merchant and Regulated Transmission: Theory, Evidence and Policy
Economists acknowledge the problems of regulated transmission but
take different views about the likely efficiency of merchant transmission.
This paper examines the evidence on alleged market failure and
regulatory failure as experienced in practice in Australia and Argentina.
In these examples, merchant transmission (broadly defined to include
private initiatives) has generally not exhibited the standard examples of
market failure but regulated transmission generally has exhibited the
standard examples of regulatory failure. Imperfect information – more
specifically, in the form of lack of coordination – has often been a
challenge whatever the approach. Policy should therefore seek to
improve the regulatory framework and to remove barriers to merchant
transmission and private initiatives. An important role for regulation is to
facilitate coordination between potential providers and users of
transmission lines
Merchant Electricity Transmission Expansion: A European Case Study
We apply a merchant transmission model to the trilateral market coupling (TLC) arrangement among the Netherlands, Belgium and France as a generic example, and note that it can be applied to any general market splitting or coupling of Europe's different national power markets. In this merchant framework; the system operator allocates financial transmission rights (FTRs) to investors in transmission expansion based upon their preferences, and revenue adequacy. The independent system operator (ISO) preserves some proxy FTRs to deal with potential negative externalities due to an expansion project. This scheme proves to be capable in providing incentives for investment in transmission expansion projects within TLC areas.transmission expansion, trilateral market coupling, Europe, financial transmission rights, congestion management
Merchant interconnector projects by generators in the EU: Effects on profitability and allocation of capacity
When building a cross-border transmission line (a so-called interconnector) as a for-profit (merchant) project, where the regulator has required that capacity allocation be done non-discriminatorily by explicit auction, the identity of the investor can affect the profitability of the interconnector project and, once operational, the resulting allocation of its capacity. Specifically, when the investor is a generator (hereafter the integrated generator) who also can use the interconnector to export its electricity to a distant location, then, once operational, the integrated generator will bid more aggressively in the allocation auctions to increase the auction revenue and thus its profits. As a result, the integrated generator is more likely to win the auction and the capacity is sold for a higher price. This lowers the allocative efficiency of the auction, but it increases the expected ex-ante profitability of the merchant interconnector project. Unaffiliated, independent generators, however, are less likely to win the auction and, in any case, pay a higher price, which dramatically lowers their revenues from exporting electricity over this interconnector.electricity markets; regulation; cross-border electricity transmissions; vertical integration; asymmetric auctions; bidding behavior
Possible biases in wind speed measurements from merchant ships
Wind speed measurements obtained from ship-mounted anemometers are biased by the presence of the ship which distorts the airflow to the anemometer. Until recently this bias had only been quantified for a few well-exposed anemometer sites on individual research ships, whereas the magnitude and even the sign of the bias was unknown for anemometers on merchant ships. Three-dimensional numerical simulations of the airflow over a typical tanker/bulk carrier have been performed to quantify the pattern of the airflow above the ship’s bridge. The accuracy of the numerical simulations has been verified by comparison to wind tunnel studies. Typically, the flow is accelerated by up to 18±6 % or decelerated by 100% depending on position. In practice, an anemometer located above the bridge should be mounted as high and as far forwards as possible
Payment Card Network Pricing - A Theoretical Approach Analyzing the Relationship between Downstream Market Characteristics and the Merchant Usage Fee
In this thesis the model of a payment card network is constructed to explore the impact of downstream market characteristics (i.e., the market where merchants and consumers interact) on the merchant and the interchange fee, thereby extending the literature’s observations of payment systems. To accomplish this, three scenarios are analyzed: firstly, a unitary payment card network with merchants under Cournot quantity competition and, secondly, under Bertrand price competition respectively, as well as, thirdly, a multi-party payment card network with merchants under Cournot quantity competition. This study yields two significant results. Firstly, the merchant and the interchange fee are found decreasing in the consumer price elasticity, the level of product substitutability and the relative frequency of card usage. Secondly, regulating the interchange fee and the merchant fee respectively is found particularly useful since, in markets with less competition where consumers already face inefficiently high prices, the payment card fees will also tend to be higher. --Two-sided markets,Payment card networks,Platform pricing,Bertrand competition,Industrial Organization,Cournot competition
