1,5 Advokatfirma AS

Independent boutique firm 1,5 Advokatfirma AS focuses on regulatory and contractual advice within the Norwegian renewable energy sector, using its experience within the industry to help climate-conscious clients with their decarbonisation strategies.

Jens Naas-Bibow served as the sole lawyer appointed by the Norwegian Ministry of Petroleum and Energy to participate in an expert commission which sought to improve the transmission of renewable electricity, discussing the licensing process for power grid facilities, potential improvements to the grid connection process, and ways to optimise the development of the power grid.

The firm advised regional power company Sunnhordland Kraftlag on regulatory matters regarding the grid connection process for a new hydropower plant. Another client in the renewable sector is developer Nordisk Vindkraft Norge, which sought the firm’s advice on contractual and regulatory matters, and negotiations with landowners, regarding the Vardafjellet Vindkraftverk wind farm.

In a project which received state aid through the Enova fund (which supports emerging green energy technologies), the firm also advised power company Glitre Energi Produksjon on regulatory questions related to the development of an innovative emergency power supply facility utilising renewable energy at a new hospital.

The firm furthermore provides electricity retail business Fortum Consumer Solutions advice across electricity retail and consumer market issues, including recently handling litigation on the legality of retail contracts for the consumer electricity market 

The firm’s two lawyers, Naas-Bibow and Frode Støle, regularly impart their knowledge on the legal regime of Europe’s electricity market. They co-authored the Norway case-study chapter in Oxford University Press’ Capacity Mechanisms in the EU Energy Markets. 

Consciously minimising its internal climate footprint, the firm runs an entirely paperless operation, with most client meetings conducted virtually.

The firm also advised the municipality of Oslo regarding its investment in the carbon capture project at the largest waste-to-energy plant in Norway; with the plant being Oslo’s largest point source of CO2 emissions, the project is a vital decarbonisation goal for the municipality.

In an ongoing matter, Emanuel Feinberg is advising Föreningen Greenpeace Norden against the Norwegian Government, with the client claiming that the award of oil and gas production licences in the Barents Sea violates the constitutional right to the environment, due to the licences’ environmental and emissions impact. The case, now brought before the ECHR, was the first to try the Norwegian constitutional right to the environment before the courts, and the first trying the legality of petroleum production licences.

For the WWF, the firm has reviewed the legality of the Norwegian government’s proposal to open a quarter of the Norwegian Continental Shelf for the extraction of mineral deposits, assessing whether this complies with existing environmental law and whether there was an erroneous procedure due to the lack of an environmental impact assessment.

A key client is rights-based rainforest protection organisation Rainforest Foundation Norway, which sought the firm’s pro bono advice on various matters; recent work for the client has focused on contract reviews.
