Renewable energy


Energy is political. Renewable energy projects are often marked by conflict and competing interests. They intersect with a wide range of policy areas—climate, environment and biodiversity, business development, infrastructure and land use, energy security, local government autonomy, and international obligations under the EEA Agreement. Project development is complex and capital-intensive, carrying significant risk for developers and other stakeholders alike.

There is broad consensus that we need more renewable energy—but much less consensus on what kind, where projects should be located, and how they should be operated.

Where politics is complex, so too is the law. Arntzen is a leading legal advisor in renewable energy and infrastructure. We support clients throughout the value chain—from early-stage development to navigating the full spectrum of regulatory frameworks. We understand the industry, we understand the regulatory landscape, and we deliver strategic legal advice to help energy companies safeguard their commercial interests within shifting political and regulatory environments.

Good diversity and cross-functional service which makes this law firm a one-stop shop. Good ability to appoint relevant lawyers for therelevant topic.
