Is the landlord required to fix electrical issues?

I am currently leasing an office space for my uniform business. This is the second time that the electricity has cut out at the office. The landlord doesn't want to fix the issue and wants to charge me to upgrade the electrical system for the office. The landlord knew we were operating a uniform business with equipment and blamed the electricity on our equipment. My lease ends on April 1, 2025. Can I get out of the lease early due to the landlord not willing to fix the issues?
