In this paper, we describe the development and current status of anti-manipulation rules as they apply to wholesale electricity and natural gas markets in the United States and the European Union, including the institutions that are responsible for overseeing these rules. We then compare and...

In this paper, we present a straightforward economic model that explains the incentives to manipulate nodal energy prices in a “Day 2” RTO market. The model distinguishes between legitimate market participation that increases overall market efficiency and manipulative behavior that distorts...

In this paper we employ a fundamental principle of classical mechanics known as the Least Action Principle to model the complex relationship between expected load and expected price in electricity spot markets. We consider here markets that feature a centralised electricity dispatch system that...

To capture mean reversion and sharp seasonal spikes observed in electricity prices, this paper develops a new stochastic model for electricity spot prices by time changing the Jump Cox-Ingersoll-Ross (JCIR) process with a random clock that is a composite of a Gamma subordinator and a...

It is crucial to model, quantify and understand the variables and dynamics that underlie the well-known extreme behaviour of spot electricity prices in wholesale markets. We explicitly model the conditional volatility and skewness of electricity prices. A GARCH-type model allowing for...

Polynomial processes have the property that expectations of polynomial functions (of degree n, say) of the future state of the process conditional on the current state are given by polynomials (of degree n) of the current state. Here we explore the application of polynomial processes in the...

Energy companies with commitments to meet customers' daily electricity demands face the problem of hedging load and price risk. We propose a joint model for load and price dynamics, which is motivated by the goal of facilitating optimal hedging decisions, while also intuitively capturing the key...

We model the impact of supply and demand on risk premiums in electricity futures, using daily data for 2003-2014. The model provides a satisfactory fit and allows for unspanned economic risk not embedded in the futures price. The spot risk premium and forward bias implied by the model are on...
