ABOUT US

Law, Energy, Decisions That Deliver Results.

For over 15 years, we have been combining legal practice with the realities of RES investments — from concept, through financing and construction, to concessions, operation, and PPA/cPPA contracts.

Why JESMAN

We operate in accordance with the law, professional ethics, and best industry practices.
We transparently communicate risks and propose implementable solutions.

Practice > Theory

Decisions based on experience from hundreds of real project steps, not on slides.

Business Outcome

We integrate law, regulations, and risks into one goal: a bankable, operational project.

Pace and Predictability

We plan the entire investment lifecycle — with foresight that saves months.

Confidentiality and Relationships

We work discreetly. The most important agreements are made in conversation, not in an online meeting.

Who am I?

Grzegorz Jeśman

My name is Grzegorz (Greg) Jeśman, and for over 15 years, I have combined legal experience with business practice in the renewable energy sector. I am a legal advisor and a manager with many years of experience.

For 8 years, I served as Vice President of the Management Board for companies implementing Poland’s largest onshore wind farm – the Potęgowo project, which is among the largest in this part of Europe. This allowed me to gain unique experience at the intersection of law, business, and technology.

Today, I support investors and entrepreneurs at every stage of RES project implementation.

In my work, I focus on practical solutions and partnership-based cooperation. I surround myself with a team of experts who – like me – believe that every investment can be conducted effectively, securely, and in compliance with applicable regulations.
