The Princeton Municipal Light Department (PMLD) has been providing electrical service
to residents and businesses in Princeton for over 100 years (est. 1912).

THE MISSION of the PMLD is to provide a safe, reliable, and economical source of
electric power for our customers, to acknowledge and implement the need for renewable
energy from within the diversity of available energy sources, and to enhance the benefits
of municipal utility ownership for our customers.  PMLD has its own elected Board of
Commissioners, General Manager, and staff that operate separate and autonomously
from the Board of Selectmen,Town Administrator, and other Town Boards & Committees.

Are you considering an Electric or Plug-In Hybrid Electric Vehicle Purchase in the near future?  
Would you be willing to participate in a Scheduled Charging Program for that Vehicle?  
If you said "Yes" to one or both questions, then please go to 'Additional Links' above and click on the documents
(Chevy Bolt 2019, Leaf 2019, Leaf Plus 2019, EV Smart Charging Flyer & PHEV charger rebate) for more information.

The Princeton Municipal Light Department (PMLD) is still part of three ongoing promotions that local
participating Nissan and Chevrolet dealerships are still offering.  There are up to $14,250.00 worth of
rebates and incentives Princeton Residents could take advantage of to reduce the cost on the purchase
of a Nissan Leaf, Nissan Leaf Plus and Chevy Bolt Electric Vehicles.  Now that the Town of Princeton has
access to reliable WI-FI, PMLD is excited to offer, in conjunction with the purchase of an Electric Vehicle,
two additional incentives for a ChargePoint Charger when you enroll in PMLD’s Scheduled Charging Program
for an Electric or Plug-In Hybrid Electric Vehicle purchased.  Validation of purchase and contract commitments
will apply.  If you have any additional questions, please call the office at 978-464-2815 during regular business hours.  
These promotions and incentives are a collaborated effort between PMLD and the Massachusetts Municipal
Wholesale Energy Company (MMWEC) as part of the Municipal HELPS Energy Conservation Program

January 2019
For the 3rd year in a row, PMLD Commissioners have voted to maintain the current electric rates.
Currently PMLD rates are LOWER than rates charged by Unitil, National Grid and Eversource.  This is possible due
to the strict management of cost control, monthly review of expenses, the long-term contract with our energy supplier,
and five-year strategic planning by the Board of Light Commissioners, General Manager and Staff. PMLD's current rate
includes a charge of $0.05/kwh to pay for the wind farm debt, maintenance and operation expenses.  The wind farm
debt is expected to retire in the 1st quarter of 2027.  Today's base energy rate ($0.1975/kwh for residential) is just slightly
higher than the 2008 energy rate 10 years ago of $0.1923/kwh before the wind farm debt was incurred.  Princeton residents
can be reassured that the Department is committed in keeping the energy rates affordable while still focused on
maximizing efforts to consume and generate green renewable energy sources.  Residents are encouraged
to participate in a greener environment by taking advantage of the HELPS energy audit and various rebates towards
the purchase of more energy efficient appliances, heating and cooling systems for their homes.  
Click on the links listed above for more information.   HELPS is the same type of energy efficient program as MASSAVE
but is sponsored by the Massachusetts Municipal Wholesale Electric Company for non-profit Municipal Light Plants.

In May 2002 an Article on the annual town meeting warrant asked voters for permission to seek financing for $3.75M
to replace the 8 old decommissioned turbines with two new larger wind turbines.  The Article did not pass.  
On February 11, 2003 the town held a Special Town Vote asking voters via Ballot Vote to vote on a Non-Binding
Question "Do you favor the Board of Light Commissioners' plan to replace the eight (8) existing wind turbines with
two (2) new larger wind turbines mounted on towers 213-230 feet high?".  The voters voted 74% in favor
(605 out of 818 votes). In June 2007 the Princeton Municipal Light Department (PMLD) in cooperation with
Massachusetts Municipal Wholesale Electric Company (MMWEC) formed the Massachusetts Municipal Light
Department Wind Energy Cooperative Corporation(MMLDWECC) to finance, own & operate the turbines. The
MMLDWECC owned and operated the two Fuhrlaender 1500 kW wind turbines located in Princeton until March
2015. In March 2015, the ownership of the turbines was transferred to the PMLD and the Wind Farm Debt was
refinanced through MMWEC 3 times to restructure the loan into short-term, long-term and bond payment schedules
to levelize payments and reduce the interest rate. 24/7 SCADA monitoring of equipment and operations are in place.  
Business Insurance policies were purchased to protect PMLD's investment. All maintenance and repairs are performed
by PMLD staff who are trained as Wind Turbine Technicians and contracts are in place with industry corporations
to provide advanced monitoring and techincal support. Weekly, Monthly and Annual inspections of both turbine are
performed and documented.  A healthy stock of invetory replacement parts and pieces are stored at PMLD. PMLD
continues to actively pursue Non-Profit Entities and offer the Sale of Wind Power the turbines generate to offset the
Debt Obligation. The Wind Farm Debt will be paid off in 2026.  Annually on average, the Wind Farm Debt is $0.05/kwh
of the $0.2475/kwh rate customers pay monthly. Visitors are welcome to walk the trail off Westminister Rd up to and
around the wind turbines to get an up-close view from the ground of these machines.         

Project History:
  • Planning, Permitting & Litigation took place for over 7 years (2002-2008) and the Costs and Partners changed Significantly
  • Construction began in 2009 just after the December 2008 Ice Storm
  • Commercial operation Commenced in May 2010
  • 1 Gearbox failure in August 2011 on the South turbine due to manufacturing defect was replaced in June 2012
  • 3 Converters have been replaced in 2015 & 2017 on the South turbine and 2018 on North turbine  
Wind Power Generation is currently sold to:
  • 8.333% is Sold to the Sterling Municipal Light Department under 10 year Purchase Power Agreement
  • 16.666% is Sold to the West Boylston Municipal Light Plant under 10 year Purchase Power Agreement
  • the Remaining 75.001% is Sold through the Real Time Energy Market for Revenue to offset the Debt Obligation

  • The Fuhrlaender 1500 kW turbines are based on the design of American Superconductor (AMSC) in Asutria.
  • There are approximately 6 of these units in the United States.
  • Each Tower height is 215 feet or 65 meters above ground level.
  • Each Tower was delivered and installed in three pieces.
  • The Tower sections were manufactured in Minnesota.
  • The maximum height of turbine structure with blade straight up is approximately 360 feet or 108.6 meters above
  • ground level (AGL).
  • The Wind Farm Site is approximately 1,450’ above sea level.
  • Length of each blade is approximately 125 feet or 37.5 meters and each blade weighs 6 tons.
  • The Blades were manufactured in South Dakota.
  • The turbine speed is 17-20 rpm’s.
  • The maximum blade tip speed is approximately 204 mph.
  • The Power Output of each turbine is 1,500 kilowatts (kW).
  • The Generator on top of each tower weights approximately 60 tons.
  • The Annual Energy Output of the two turbines is approximately 4,000,000 kWh’s.
  • Both turbines generate the equivalent annual energy consumption of 330 homes.
  • The wind turbine manufacturer is Fuhrlaender from Germany.
  • The purchase and installation cost for the two turbines was approximately $7,300,000.
  • The minimum wind speed to start producing energy is 7 MPH or 3 meters per second.
  • The maximum wind to produced rated power output is 27 MPH or 12 meters per second.
  • The Cutout wind speed or wind speed too great for a turbine is 45 MPH or 20 meters per second.
  • The Survival wind speed is 133 MPH or 59.5 meters per second.
  • The expected lifespan of the wind turbine is 20-25 years.
  • Durng a power outage the turbines will not operate to prevent back-feeding into the electrical distribution system.
  • The wind turbines use an anemometer and wind vane to sense wind speed and direction.  
  • This data tells the wind turbines what direction to point towards and when to start or stop.
  • The blades act just like airplane blades and are lifted by the wind to turn the generator shaft.  
  • The pitch of each blade is controlled to optimize energy production at various wind speeds.
  • The electricity generator feeds the electrical grid and feeds the customer load or demand for energy in the area it is connected to.
  • You cannot physically send the electricity generated from our turbines to someone else, that is handled by financial contracts.
