Guarantees of Origin: Ensuring 100 per cent renewable power in Europe

A Guarantee of Origin is a EU guarantee that a given amount of power is produced at a particular power plant. It is a voluntary certification scheme allowing consumers to choose a source of production, typically the choice between renewable and non-renewable electricity.

Torun Revdal heads the unit Nordic Green Products and works with Guarantees of Origin for electric power in Statkraft's Market and IT business area.

Power is produced, fed into the grid and consumed regardless of its origin; from fossil fuels or from renewable sources. But how can energy suppliers and businesses who wish to choose power from renewable sources act upon their choice?

By purchasing Guarantees of Origin alongside their power in Europe. Internationally, they can rely on I-RECs (International Renewable Energy Certificates) and market-based certificates which fulfil the same goal.

A reliable tracking mechanism

A Guarantee of Origin tracks the source of the power bought by companies and energy suppliers in the market back to the power plant that produced it, thus answering the questions: which type of plant is it and where is it located?

Since electricity cannot be packaged and labelled with this information, the tracking happens separately. It takes the form of certificates, registered through a reliable electronic mechanism for every MWh of power produced.

In the market, the electricity and the renewable energy certificates are sold separately. By buying the certificates alongside their electricity, businesses and suppliers then hold a tangible proof of renewable energy. This enables them to act upon their choice and to meet sustainability and compliance targets.

“Some power suppliers purchase Guarantees of Origin for all their customers, so if you choose them, you’re assured that you get renewable energy. This is very common in Sweden and Germany,” explains Torun Revdal, head of the Nordic Green Products unit in Statkraft’s Market and IT business area.

“Other power suppliers give the customer a choice of whether or not to purchase Guarantees of Origin,” she says.

The EU’s latest Renewable Energy Directive however requires electricity suppliers marketing their electricity contracts as renewable to document this with Guarantees of Origin, she further explains.

Facts about Guarantees of Origin

  • Certification scheme documenting that a given amount of power is produced by a specific power plant and thus stems from a renewable or non-renewable energy source.
  • Introduced with the EU's first Renewable Energy Directive in 2001.
  • One Guarantee of Origin is equivalent to 1 MWh of electricity produced.
  • Businesses or individuals wishing to document the origin of their electricity consumption and its greenhouse gas footprint may choose to buy electricity certified with a Guarantee of Origin and thus help increase the demand for renewable energy.

Consumer power

Companies that want to document their power consumption as renewable can either purchase Guarantees of Origin through their power supplier or directly in the wholesale market, often from power producers or through brokers.

The Guarantee of Origin scheme does not directly affect the sale of electricity, nor does it affect the flow in the grid. Instead it affects cash flow, by ensuring that the money the customer pays for Guarantees of Origin from a specific power plant actually goes to the power producer.

“In this way, energy customers can exercise consumer power and support certain power plants, technologies, locations and even recent construction projects and official labels such as EKOEnergy or TÜV,” explains Revdal.

They can achieve several goals:

  • Reduce their Scope 2 emissions and meet their sustainability targets.
  • Show their customers, financial partners and investors that they are climate-responsible and future-proof.
  • Remain a supplier or become a supplier to companies that have set carbon footprint limits for their suppliers.
  • Cover needs for renewable energy within a country or across several markets depending on their choice and location of business.

Increasing demand

Statkraft sells guarantees from both hydropower plants and wind farms.

“We also purchase Guarantees of Origin from other producers and resell them. Germany has been the most important market for exporting Norwegian Guarantees of Origin in recent years, but we're also experiencing increased demand in the Nordic countries,” says Revdal.

“Given the large concentration of hydropower in Northern Europe, some companies still choose to base their climate reporting on the production mix within their geographical area. However, more and more companies are choosing to use Guarantees of Origin, which is the best-practice approach in Europe,” she adds.

Demand for renewable energy is growing.

“This is linked to the growing focus on sustainability in society in general,” says Revdal.

One important driver is companies with a green agenda. RE100, a global association of more than 260 influential companies, have committed to consuming 100 per cent renewable energy by 2050. By purchasing Guarantees of Origin, they exercise their consumer power to accelerate the transition from fossil to renewable energy. Companies such as Coca Cola, NIKE, IKEA, BMW, Sony, Google, Apple, Microsoft and Facebook are all part of the RE100 initiative, and in Norway Nordea, DNB and Elopac have joined.

“The RE100 and other companies are now also setting environmental requirements for their subcontractors, which could potentially trigger an exponential growth in demand for renewable energy,” says Revdal.
