Hello Nicolas, thank you again for the constructive meeting. As discussed, it is perfectly fine for us to structure the contract via Blueray Services. We have also adjusted our proposal accordingly: the medium-voltage scope has been revised, as the monthly component was not required in this case, which allowed us to significantly reduce the costs. In addition, we have optimized the pricing for the structure maintenance. I will visit the site next week. Should any questions arise from our side, I will get back to you. Likewise, if you have any questions regarding our proposal, please feel free to reach out at any time. We would be pleased if this process leads to a successful collaboration.
