There’s a lot of talk in California these days about imposing fixed monthly charges on residential electricity bills. The large investor-owned utilities in California have small or no fixed charges,instead collecting all of their revenue from households through usage-based charges, called volumetric pricing.
No EU policy can be perfect – it will inevitably be a compromise between a good cause and a due cause. However, we are now at a critical turning point, as several pillars of former Barroso’s EU energy policy have already collapsed, prompting an update or an entire overhaul.
EU policies to integrate energy markets, promote renewable energy, and diversify supply are aiming at a competitive and sustainable European power sector. The resulting dynamics should largely affect the systems of electricity generation, transportation and storage in Europe: With increasing market integration come new new competitors; coal and gas power plants face new renewable challengers domestically and abroad; and diversification towards new suppliers will bring new trade routes and infrastructure. All in all, EU policies to integrate power markets, promote renewables, and diversify supply will thus profoundly reshuffle national energy assets. The impact of the three EU policies is thus likely to have considerable ‘geopolitical’ implications for individual member states and affect their capability to negotiate, agree on, and/or implement further measures. We conduct a thought experiment which explores potential benefits and losses for individual member states implicit to Europe’s ‘energy transition’, and the political concerns which may be expected to arise as a consequence.

European power markets are being confronted with an unprecedented transition process toward a low-carbon power system. The speed and complexity of this shift are raising serious challenges and operational difficulties. The successful increase in the deployment of variable renewable electricity technologies is bringing the EU objective of raising the share of these technologies in its energy mix to 20% by 2020 closer to an attainable reality. But there are deep concerns about the continuing impacts of this transition, especially as it is further expanded to include a substantially larger share of renewables by 2050.
In order to better integrate their electricity markets, regions must first have confidence that when push comes to shove during times of capacity scarcity, their neighbours will continue work with them, and not against them. That means paying more attention to the rules for security of electricity supply. If you can’t count on your neighbours in times of need, you want to make sure that you have enough steel on the ground in your own jurisdiction. But with this kind of mindset, markets can’t just function properly.
A brief post concerning electricity restructuring that looks back over the last 20 years. Around that time I started giving a talk titled “If electricity restructuring is so great, why does everybody hate it?” Back then, several states like Illinois and Maryland were actively pursuing options to “re-regulate” markets that they had at least partially restructured.

Traditionally, the distribution charge paid by consumers of electricity connected to a grid is based on the capacity for which they subscribe and the number of kWh withdrawn during a given period. Energy consumption is however actually a poor approximation of the willingness to pay for being connected. Additionally, except for thermal losses, the cost incurred by distribution system operators (DSO) does not depend on the quantity transported. The main raison d’être of the kWh index is that it is indispensable for producers and suppliers. Since it is an existing gauge provided by installed meters, why not use it for distribution?

Changing the rules by which nuclear power stations are judged to be safe or not may sound unpalatable to some, even outright dangerous. But this is what the Office of Nuclear Regulation is considering in order to extend the life of Britain’s ageing reactor fleet. Rest assured, however, such things are done carefully.

Since the beginning of electricity grids, demand has fluctuated and supply has been made to follow along. But for decades, economists and some grid engineers have dreamed of having demand play a more active role in balancing the system. With increasing use of intermittent renewable energy resources, now is the time to make that demand-response dream come true. But we can only get there if we clear up a common misconception in the world of electricity policy.

“European consumers’ electricity and gas prices have risen and are still rising,” is a good summary of a recent report, Energy Costs & Prices in Europe, released by the European Commission in Brussels. Moreover, whilst almost all Member States have seen a consistent rise in consumer prices of electricity and gas, the differences between national prices remain large: consumers in the highest priced Member States are paying 2.5 to 4 times as much as those in the lowest priced Member States.
