We recently switched our electric bill from National Grid to Renaissance. When we first reach out to them, their customer service was awesome. They answered my questions quickly and even followed up with me on my questions. I was happily surprised when I received an email from them asking us how we were enjoying our first month with them. It seemed like they really were invested! We just received our first bill with them as a provider and we happily saved over $100 in one month! We would highly recommend this company as a great alternative source as well as a company with great customer service!
