There remain barriers to scaling up off-grid barriers, and the placemat below identifies some of the practical strategies that companies can implement to help drive the growth of the new business models that they develop.  … Read More


The importance of cost reflectivity has been central to economic regulation.  Price signals that reflect the true underlying cost of an action are important when trying to incentivise the right behaviours through the whole value chain.  In the power sector, this is true whether we are referring to decisions made by end consumers, or decisions… Read More


Since the deregulation of utilities in the 1990s, a conventional wisdom has been established whereby some utility functions have been subject to revenue regulation, and other utility functions have instead operated in a competitive marketplace.  As a general rule, in Europe as least, power generation and upstream activities are subject to competition, while network activities… Read More
