Navigare necesse est: Rerouting network companies toward decarbonisation

By Zsuzsanna Pató
Changing the course of a sailboat requires coordinated action. The skipper announces the manoeuvre to the crew, turns the rudder and works with the crew to readjust the sails. To achieve the maximum cruising speed with the prevailing winds and currents, all sails need to be swiftly positioned at just the right angle. The need for fluid coordination also applie...

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

Emissionspreise sind nicht alles

By Louise Sunderland, Andreas Jahn
Preise für Emissionen sind nicht alles, vielmehr ist die sinnvolle Verwendung der Einnahmen entscheidend. Schlüssig belegt ist, dass Energieeffizienzprogramme gut abschneiden. Auch das Ordnungsrecht – zum Beispiel Mindeststandards – helfe bei der Einhaltung der Klimaziele. Das Klimapaket der Bundesregierung ist derzeit in aller Munde. Wie auch die darin ... Read More

In 2013, RAP released a pathbreaking publication, Recognizing the Full Value of Energy Efficiency. We refer to the main concept of this paper as "the layer cake," after its centerpiece concept analogizing the multiple benefits of energy efficiency as layers in a cake. Health benefits, both for individual participants in an efficiency program and for society as a ... Read More
