It is the top trader of liquefied natural gas LNG , buys and sells power, biofuels, chemicals and carbon credits, and now aims to use its pole position to snare a large chunk of the fast-growing low-carbon power market. Trading has been key for oil majors for decades, allowing them to use their global operations to quickly take advantage of changes in supply and demand. At the same time, Shell plans to boost its consumer base by expanding its electricity supply business for homes and its network of electric vehicle charging points, as well as signing long-term corporate power purchase agreements PPA.
Shell already has 45, retail outlets worldwide, far more than its European rivals, and it is planning to add another 10, by As a major biofuel producer, Shell wants to ramp up its production of fuel made from plants and waste as an alternative source of energy for transportation, the sources said. While still a niche market, hydrogen has attracted huge interest in recent months as a clean alternative to natural gas for heavy industry and transportation.
Hydrogen, and so-called green hydrogen which is made solely with renewable power, comes with high costs and infrastructure challenges though Shell is already investing. Its push will centre initially on Europe, where it is developing a hydrogen hub in Hamburg, Germany, and it is one of several firms developing a hub in Rotterdam in the Netherlands.

It is also looking to expand into the United States and Asia. The U. Shell will still expand its renewable capacity, especially in offshore wind farms where it believes it has an advantage after years of operating offshore oilfields, but the business will centre on profitability rather than size, the sources said. We first empirically test whether the California Independent System Operator's CAISO existing two-settlement electricity markets are efficient, and if not, to what extent CB improves market efficiency.
We examine the theoretical and empirical tools intended for other financial markets to help us understand the efficacy of CB in the forward and spot electricity markets.
In the light of the efficient market hypothesis, Jensen uses the zero-profit competitive equilibrium to describe the condition for market efficiency. This definition of market efficiency directly converts the test of market efficiency into the assessment of return behavior. Following this methodology, we empirically test for market efficiency by evaluating the performance of trading strategies based on market data in the CAISO electric power markets.

Our backtest results show that profitable trading opportunities continue to exist in the post-CB period, but the profitability decreases substantially. The decrease in profitability in the post-CB period indicates the improvement of market efficiency, and demonstrates the benefit of CB.
The profitability in the post-CB period, however, conveys empirical implications that can be interpreted differently, depending on the level of competition and the level of risk aversion of virtual traders. We further examine the use of DLMP to improve system efficiency in future power systems. The distribution system operator DSO determines distribution locational marginal prices DLMPs by solving the social welfare optimization for both the conventional household demand and the EV demand with marginal costs exogenously set to LMPs.
We show mathematically that the socially optimal charging schedule can be implemented through a decentralized mechanism where retailers and EV aggregators respond autonomously to the posted DLMPs by maximizing their individual net surplus in the perfectly competitive local DSO market. We further investigate the problem of designing pricing mechanism when LMPs are uncertain. Skip to main content.
