No, signing up with Meltek will not change your electricity supply source.
The supply company you have ( for example ConEd) will remain your deliverer, supplier (unless you previously had a different supply company), and biller for your electrical service.
Meltek is not a supply company (often referred to as an "energy service company, or "ESCO"), and so we do not replace your electrical supply source or change anything about your electric supply relationship with ConEd.
Instead, we are an approved aggregator of ConEd that brings together electric customers who are willing to get paid to save energy at high electric demand times. Doing so saves the utility company money, saves you money, and also benefits the environment by reducing air pollution and greenhouse gas emissions. So, with confidence, you can sign up today (link to https://meltek.page.link/join-meltek) with Meltek and not affect where your electric supply comes from.
