PMLD'S MISSION STATEMENT:

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.

WIND FARM NEWS:

08/29/2017 The North Turbine has been repaired and is back up and running.  PMLD performed the
repair in-house and the turbine was just offline for approximately 7 days.  Both turbines are operational at this time.


SUMMARY:

Princeton Municipal Light Department (PMLD) in cooperation with Massachusetts Municipal Wholesale Electric Corporation
(MMWEC) formed the Massachusetts Municipal Light Department Wind Energy Cooperative Corporation (MMLDWECC)
which owned the turbines. The Massachusetts Municipal Light Department Wind Energy Cooperative Corporation 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.

The Fuhrlaender 1500 kW turbines are based on the design of American Superconductor (AMSC) located in Woerthersee,
Austria. There are approximately 6 of these units in the United States.

Project History:
Planning & Permitting 2003-2008 Construction 2009
Commercial operation commenced January 2010.
Gearbox failure in south turbine August 2011 due to manufacturing defect has been replaced June 2012. Both turbines are
now operating smoothly. Please refer to production charts for production history.

Wind generation production is sold to:
Sterling Municipal Light Department under 10 year PPA (8.333% total output and capacity)
West Boylston Municipal Light Plant under 10 year PPA (16.666% total output and capacity)
Remaining 75.001% is sold on the Real Time Market through MMWEC

All operations and maintenance are by the PMLD department staff. In association with AMSC the PMLD operates and maintains
the SCADA system software. 24/7 monitoring and technical support is also supplied through contract with AMSC. A contract is
also in place for additional gear box monitoring through Bachmann Electronic Corporation.

The Wind Farm Debt Obligation was refinanced through MMWEC Pool Financing into a Long Term Bond to be paid off in 2026.

FUN FACTS:

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.

When the town experiences a power outage, the turbines will not operate to prevent back-feeding into the electrical distribution
system as the lineworker’s work to restore power.

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 generally 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.

IMPORTANT NEWS AND UPDATES:

October 1, 2017 - PMLD has reformatted the monthly invoice to provide ratepayers with a cost
breakdown that defines the rate as it relates to energy purchases, department operations and windfarm operations
as a clarification of information similar to what National Grid provides.  Your rate is still $0.1975 + $0.05 = $0.2475
If you need further explaination please call PMLD.
