How NHH Researchers Influence Energy Policy
Congestion management and regulation of the electricity market are challenging but essential tasks. At the forefront of addressing these issues were Endre Bjørndal and Mette Bjørndal.

What happens when academic research moves from theory to actionable policy?
In Norway’s electricity market, it has led to fairer pricing, smarter regulation, and greater efficiency, partly due to the long-standing contributions of Professors Endre Bjørndal (1966-1924) and Mette Bjørndal, both at the Department of Business and Management Science.
A pivotal question in the electricity market has been how to handle congestion in networks.
Earlier studies by the two NHH Professors compared the Nordic zonal pricing method with nodal pricing benchmarks. This research used conceptual and simplified models to highlight the differences, trade-offs, and potential inefficiencies inherent in these two pricing methods.
The OptFlow model
In 2012, the Bjørndals played a leading role in developing and applying the OptFlow model - a computational tool used to analyze and optimize electricity network flows, particularly in the context of congestion management and market design in wholesale electricity markets.

It was developed as part of research commissioned by NVE. The model made it possible to compare different congestion management methods in a more realistic network, using historical real data from Nord Pool.
Further, this model informed discussions on wholesale pricing and congestion management, directly contributing to expert committees and guiding the Ministry of Energy[1].
Transforming Regulation of Network Companies
Since the Norwegian electricity market reform in 1991, the regulation of network companies has been an ongoing focus. The Bjørndals’ research supported NVE in choosing and refining a DEA-based yardstick regulation model introduced in 2007[2].
Their work addressed implementation challenges like data calibration, adjusting for efficiency biases, and compensating for reporting lags—solutions that were later implemented by NVE.

These improvements ensured fair revenue caps and maintained profitability in the capital-intensive electricity distribution industry.
Long-Lasting Industry Collaboration
Through commissioned reports, industry collaborations, and the Elbench project (launched in 2015), the researchers provided continuous input on productivity, innovation, and market design.
Their work on marginal loss pricing, documented in a 2010 SNF report, was followed by changes implemented by Statnett in 2015, improving pricing practices.
By bridging theory and practice, NHH researchers have shaped both regulatory frameworks and operational strategies, helping regulators like NVE and industry players like Energy Norway navigate complex market challenges.
The legacy of this work continues to resonate - in Norway and internationally, offering tools and perspectives that help electricity markets function more efficiently and fairly.
