With its package of measures against the energy crisis, the European Union also wants to alleviate the liquidity stress that suppliers are suffering from because of so-called margin calls and security requirements on the energy exchanges.

To this end, Brussels is seeking talks with the supervisory authorities, according to a document from the EU Commission.

The move is part of a program unveiled by European Commission President Ursula von der Leyen on Wednesday, which also includes expected measures to cut electricity consumption and cap electricity prices, all designed to curb soaring energy costs.

In addition, the EU will take action to alleviate the crisis in energy exchanges caused by the increasing need for security.

"The Commission will work with relevant securities and banking regulators to identify ways to allow market participants to find collateral to meet margin calls," the document reads.

It is also about a price cap for electricity from sources other than gas and consumer support.

A tax on fossil fuel producers, a price cap for Russian gas and a binding target for reducing electricity consumption are also part of the package.

Time is of the essence as the heating season draws inexorably closer.

"We see sometimes astronomical electricity prices for households and companies and enormous volatility on the markets," said von der Leyen to journalists in Brussels on Wednesday.

"We will therefore propose a number of immediate measures that can protect particularly affected consumers and companies and help them adapt." According to a draft regulation available to Bloomberg News, the electricity price cap could be EUR 200 per megawatt hour and would be off for electricity generation Wind, solar and geothermal, hydroelectric power, biomass, landfill gas, sewage gas, biogas, nuclear power, lignite and crude oil apply.

As a result, the shares of large electricity producers rose sharply yesterday.

The Austrian Verbund AG, which uses almost exclusively hydropower, closed 13 percent higher, RWE AG 7.2 percent, the Danish Ørsted A/S 4 percent.

Jens Zimmermann, senior analyst at Credit Suisse, welcomed that the EU's proposed price cap "is high enough not to discourage future investment in non-gas-producing technologies."

Emergency meeting of EU energy ministers

The Commission's proposal will be discussed with member countries' energy ministers at an emergency meeting on Friday.

Once politically sanctioned, the commission will present draft legislation with more details.

"The Commission's approach is good because it tries to lower the price of electricity for consumers while focusing on energy savings and reducing peak demand," said Ville Niinsito, Green MEP and former Finnish environment minister.

"Investments in cheap renewable energy and energy efficiency must be maintained as a sustainable way out of the energy crisis."

The EU also proposes two targets to reduce demand.

The first calls for measures to reduce the total electricity consumption of all consumers by 10 percent to 15 percent.

The second targets the most expensive hours of production and mandates a mandatory reduction in net power consumption of at least 5 percent during peak periods.
