Building on models that represent inter-temporal constraints in the optimal production decisions for electricity generation, the paper analysis the resulting costs and their impact on prices during the day. We linearise the unit commitment problem to facilitate the interpretation of shadow...

The Great East Japan earthquake and tsunami on March 11th 2011 caused mass destruction, significant loss-of-life and a large displacement of people. It also placed significant strain of Japan’s electricity-generating infrastructure. There was a significant reduction in capacity due to the...

We present a dynamic model of the indigenous natural gas industry in the UK. The model has been built using a system dynamics approach. Using the model several scenarios have been analysed. We found that management of the supply-side policy alone cannot substantially postpone the discovery,...

This paper explores demand side management (DSM) strategies, including both demand response and energy efficiency policies. The aim is to uncover what features might strengthen DSM effectiveness. We first look at key features of residential energy demand and the limits to energy indicators. We...

In recent years smart metering of electricity demand has attracted attention around the world. A number of countries and regions have started deploying new metering systems; and many others have set targets for deployment or are undertaking trials. Across the board advances in technology and...

The six Persian Gulf monarchies are home to some of the world’s largest hydrocarbon reserves, and also some of the cheapest energy prices and highest per-capita consumption. Government subsidies based on socio-political objectives have contributed to regime longevity, but they have also...

In the midst of a shortage of natural gas, Abu Dhabi has launched an investment into renewable energy. Why? Will renewables allow the Persian Gulf sheikhdom to meet rising electricity demand without simultaneous increases in conventional power? No. Even in one of the world’s sunniest places...

The Earth's climate is changing and the release of carbon dioxide (CO2) is recognised as the principal cause. To meet legally binding targets, UK GHG emissions need to be cut by at least 80% of the 1990 levels by 2050. With an increase in future fossil fuel use, Carbon Capture and Storage (CCS)...

The traditional measure of market power is the HHI, which gives implausible results given the low elasticity of demand in electricity spot markets, unless it is adapted to take account of contracting. In its place the Residual Supply Index has been proposed as a more suitable index to measure...

We study the effect of price cap regulation on investment in new capacity in an oligopolistic (Cournot) industry, using a continuous time model with stochastic demand. A price cap has two mutually competing effects on investment under demand uncertainty: it makes the option of deferring...
