Regular Meeting Sep 19, 2016

The regularly scheduled Board of Commissioners (BOC) meeting began at 1:00 p.m. on Monday, September 19, 2016 in the Littleton Water and Light (LWL) conference room. Present were Commissioner Eddy Moore, Commissioner Perry Goodell, Commissioner Ralph Ross, Financial Director Cheryl Wilkins, Operation Manager Richard Herrington and Superintendent Thomas Considine.

MINUTES REVIEW:

The minutes of the September 6, 2016 regularly scheduled Commissioners meeting were reviewed. Commissioner Goodell made a motion to accept the minutes as presented, seconded by Commissioner Moore.

The vote was in favor of the motion 3-0-0.

FINANCIAL DIRECTORS REPORT:

Mrs. Wilkins reviewed the financial statements for the month ended July 2016 with the Commissioners. Several discrepancies as compared to budget were discussed and explained by Mrs. Wilkins.

SUPERINTENDENT/GENERAL MANAGERS REPORT:

1. As a direct result of a difference in the total purchase volume the wholesale power supply procurement that was scheduled for last week will occur on Wednesday, September 21, 2016. The requests for proposals were distributed on September 15, 2016 soliciting various on and off peak resources and are due at 1:30 p.m. on Wednesday. The anticipated cost per Mwh appears to be about $44.00 for 2017 for on peak power resources.

2. The LWL system received low voltage as a result of system upgrades being made by National Grid that affected the (3315 high line) source power supply from Comerford Hydroelectric station. Normally high side source voltage is received at about 20,500 volts when being supplied from both Comerford and Moore Dam stations. When Moore Dam was deactivated for ease of construction, Comerford station output could not provide/hold the adequate voltage. This resulted in a voltage drop of about 2,000 volts between Comerford and Littleton.

The low voltage, in excess of the standard (10% plus and minus) caused some of the LWL customers that are metered on the high side (equipment metered at 34.5kv) to drop out and run on their local generation. Customers on the distribution side that are serviced through a substation were not affected, as the substation regulators compensated for the drop in supply voltage. Though customers were not affected the regulators in the substation were operating at close to their maximum output. Thankfully the weather and outside temperatures were moderate which helped to minimize the effects of the voltage drop across the system by minimizing system loads.

When made aware of the voltage drop National Grid worked with LWL and their contractor to return the voltage to its normal operating level and dual supply sources. The heavy voltage drop appears to be a function of the poor line quality and high resistivity resulting from the existing deterioration in the overhead lines between Comerford Station and Pattenville.

3. The insurance adjusters from Primex (property liability insurers) reviewed the damage to truck 713 as compared to the repair estimate provided by LWL. The damages resulted from the motor vehicle accident on Lafayette Avenue on August 31, 2016 when a pickup truck back directly into the passenger side of truck 713. The estimate to repair the truck was for about $2,700, LWL is responsible for the deductible of $1,000. The deductible should be reimbursed when the total cost of the claim is subrogated through the insurance company of the driver (USAA) at fault that caused the damage.

4. Maintenance on several regulators at the South Street and Lafayette Avenue substations is being schedule. As a result of a build-up of water vapor in the oil and some dangerous gases due to arcing TSI Transformer Service (contractor) will be required to filter out the water and excess gases. To preserve the viscosity of the oil and the insulating/cooling functionality that the oil provides the water will be removed through a mechanical process called dehydration. Similar to the water vapor removal potentially dangerous levels of gases, generally ethylene, are removed through a process of degassing. The excessive level of gas in the equipment is a by-product of arcing within the regulators resulting from the tap changer operations.

ADJOURNMENT:

Commissioner Ross made a motion to adjourn the meeting, seconded by
Commissioner Goodell.

The vote was in favor of the motion 3-0-0.

Meeting adjourned at 1:55 p.m.

The regularly scheduled Commissionerís meeting is held twice monthly on the first and third Monday, at 1:00 p.m., in the Departmentís conference room.
