Cost Allocation: New Approaches for a New Era

By Jim Lazar, Paul Chernick, William Marcus, Mark LeBel
Setting electric utility rates has traditionally been a three-step process: first, determining the revenue requirement; second, determining how to equitably divide costs among classes of ratepayers; and third, designing the rates themselves. That second step, cost allocation, is a process that has been around for decades, and many jurisdictions have created de... Read More

A Hearty Bowl of Texas Soup: How ERCOT Keeps the Lights On

By Michael Hogan
ERCOT (or the Electricity Reliability Council of Texas, the independent system operator of that state’s stand-alone wholesale market) has confounded the doomsayers once again. Despite dire predictions that ERCOT lacked sufficient generation capacity, it came through the peak summer season of 2019 without any firm load curtailments, despite a hotter-than-normal ...

UK capacity market déjà vu: A solution that’s still in search of a problem

By Philip Baker, Michael Hogan
In November 2018, the EU General Court ruled in favour of a legal challenge mounted by Tempus Energy to the Directorate General for Competition’s (DG COMP) approval of the capacity market in Great Britain. In its challenge, Tempus successfully argued that, due to serious flaws in the design of the capacity market, DG COMP should have had doubts over its compati... Read More

Stuck in the past: Energy performance certificates hold back heat decarbonisation

By Jan Rosenow
In 2014, we bought an old Victorian house in Oxford, UK, well aware it needed major renovation work. Our energy performance certificate (EPC), which shows the energy performance of a building, was a poor grade “E” on a scale of A to G, with A being the highest performing category. We have since carried out a major refurbishment programme, installing underfloo... Read More
