MMLD Rates


MMLD Residential Electric Rates contain two major components:

  • Fixed Base Rates — these fees recover a portion of our fixed costs including the expense of maintaining our local distribution system lines, transformers and meters, MMLD employee wages, pension obligations, ongoing vendor expenses to maintain our townwide meter infrastructure, customer billing system, IT systems and support, and vendor expenses for engineering, system testing, regulatory filings and vegetation management
  • Variable KWH-based Electric Energy Rates — these fees directly recover our Wholesale Energy Costs. These costs vary monthly in volume and unit price, and represent a changing mix of power suppliers
