Commissioning HVAC Performance Testing Energy Audits Project Management

Retro-Commissioning Facility Management Consulting Energy Procurement

July 29, 2011 Mr. Bruce A. MacLeod City Manager City of Cape May 643 Washington Street Cape May, NJ 08204-2397 Re: EXECUTIVE SUMMARY FOR CITY OF CAPE MAY STATE OF NEW JERSEY LOCAL GOVERNMENT ENERGY AUDIT Dear Mr. MacLeod: Dome-Tech was retained by City of Cape May, as a pre-qualified participant in the Local Government Energy Audit Program, to perform an energy audit. The objectives of the energy audit were to evaluate the City’s energy consumption, establish baselines for energy efficiency and identify opportunities to reduce the amount of energy used and/or its cost. The scope of the audit is standardized under the Program, and consisted of the following:

Benchmarking historic energy consumption utilizing EPA Energy Star’s Portfolio Manager

Characterizing building use, occupancy, size, and construction

Providing a detailed equipment list including estimated service life and efficiency

Identifying and quantifying Energy Conservation Measures (ECMs) and Water Conservation Measures

Evaluating the economic viability of various renewable/distributed energy technologies

Performing a utility tariff analysis and assessing savings potential from energy procurement strategies

Providing the method of analyses Based upon data received for the twelve (12) month period April 2010 – April2010, for the facilities included in this study, the City had an annual expenditure of:

Electricity: 2,560,330 kWh at a total cost of $487,227.10

Natural Gas: 65,270 therms at a total cost of $124,026.65

Please refer to Section 2 of this report for a detailed list of identified Energy Conservation Measures (ECMs), along with a summary of their preliminary economics (estimated project cost, estimated annual energy savings, applicable rebate(s), etc.). In this report, all identified ECMs are ranked and presented according to their simple payback; however, please note that the master ECM table can also be sorted by building, by measure type, etc. If all identified ECMs were to be implemented, they would provide the following estimated benefits to the City of Cape May:

Total annual electrical savings: 393,970 kilowatt-hours; 15%

Total annual natural gas savings: 15,490 therms of natural gas usage; 24%

Total annual water savings: 815,000 gallons

Total annual cost savings: $83,275; 14%

Total annual CO2 emissions reduction: 221 tons

Total net estimated implementation cost: $1,188,215

Total average simple payback: 14.3 years A summary of the projects that are recommended for implementation includes the following: installing new boilers; installing vending machine and personal computer power management devices; installing piping insulation; installing low-flow faucets, toilets and waterless urinals; upgrading lighting; and replacing kitchen equipment. Please see the report for a full list of recommended ECM’s. Distributed/Renewable Energy Systems were also reviewed with the following conclusions:

Dome-Tech considered three different types of wind turbine technologies that consisted of both building-mounted and traditional ground-mounted variety. Ground-Mounted is not feasible for a majority of these sites due to space constraints and the surrounding buildings. The Building-mounted wind turbine projects at the Waterworks Building and Elementary School appear to be the only technically viable options. Should the City decide to pursue a wind turbine project, Dome-Tech recommends commissioning a more detailed study.

Roof-mounted photovoltaic systems ranging in size from 163kW - 232kW dc, could provide approximately 13% - 82% per building of the City’s annual energy usage was assessed for implementation at each site.

CHP (Combined Heat and Power), Fuel Cells, and Micro-turbines were also considered and not recommended for any of the buildings due to a lack of year-round thermal loads.

The City’s data was entered into the US EPA ENERGY STAR’s Portfolio Manager database program. Buildings with scores of 75 or higher may qualify for the ENERGY STAR Building Label. Some of the City’s buildings were not eligible for an Energy Star score, due to building type. In order to receive an Energy Star rating, more than 50% of a building must be defined by one of the following space types: Bank/Financial Institution, Courthouse, Hospital (Acute Care and Children's), Hotel, K-12 School, Medical Office, Office, Residence Hall/Dormitory, Retail Store, Supermarket, Warehouse (Refrigerated and Non-refrigerated), Wastewater Treatment Plant, or Data Center. For the buildings that were not eligible for a score, the average Source Energy Use Index (EUI) was provided as an alternate benchmark. Please see the report for individual facility information. A water conservation audit was performed. If the City of Cape May were to implement low flow faucets and waterless urinals, approximately 815,000 gallons can be saved annually and a total of 40 therms can be saved from domestic hot water heating. Regarding the procurement of utilities, Dome-Tech understands that the City of Cape May facilities in this study are served by thirteen electric accounts behind Atlantic City Electric Company and twelve natural gas accounts behind South Jersey Gas Company under a variety rate classes, both electricity and natural gas accounts are served by a supplier company.

During the development of this audit, Dome-Tech was assisted by other facility personnel, who were both knowledgeable and very helpful to our efforts. We would like to acknowledge and thank those individuals. Sincerely, Derek James Senior Energy Engineer

Greenhouse Gas Emission Reduction

Implementation of all identified ECMs will yield:

393,970 kilowatt-hours of annual avoided electric usage.

15,490 therms of annual avoided natural gas usage.

This equates to the following annual reductions:

221 tons of CO2;

-OR-

38 Cars removed from road;

-OR-

60 Acres of trees planted annually

The Energy Information Administration

(EIA) estimates that power plants in

the state of New Jersey emit s 0.666

lbs CO2 per kWh generated.

The Environmental Protection Agency

(EPA) estimates that one car emits

11,560 lbs CO2 per year.

The EPA estimates that reducing

CO2 emissions by 7,333 pounds

is equivalent to planting an acre of

trees.

Energy Conservation Measure (ECM) #1: Destratification Fans

Due to a high ceiling in the Franklin Street School, thermal stratification is occurring. A

4°F temperature difference exists between the floor and the ceiling. The heat is rising

and is being trapped near the ceiling.

While the heat remains in the ceiling space, the thermostat is at eye-level. Under this

scenario, the heating system cycles more frequently than it should.

Destratification fans would gently re-distribute the heat at the ceiling back down to the

floor.

ECM #2: Programmable Thermostats

A review of the maintenance building showed that the rooftopunits were controlled by non-programmable thermostats.

Dome-Tech recommends replacing the non-programmablethermostats with programmable thermostats andimplementing temperature setback.

Installing programmable thermostats will provide scheduledtemperature control to prevent overheating and unnecessarycooling when the building is unoccupied.

ECM #4: Vending Machine Power Management

Dome-Tech recommends installing a vending machine power

management device on all vending machines.

The device uses a passive infrared sensor to power down the machine

when the area surrounding it is vacant. It monitors the room’s

temperature and automatically re-powers the cooling system at one- to

three-hour intervals, independent of sales, to ensure that the product

stays cold.

The microcontroller will never power down the machine while the

compressor is running, eliminating compressor short-cycling. In addition,

when the machine is powered up, the cooling cycle is allowed to finish

before again powering down (reduces compressor wear and tear).

ECM #5: Computer Power Management System

According to staff, the majority of the City’s computers are left on continuously, wasting unnecessary

energy.

Installing a computer power management system will allow IT administrators to reduce per-PC operating

cost by reducing energy consumption via shutdown, standby and hibernate for PC’s and sleep for monitors.

Additionally, the software has the capability to set up profiles to optimize time of day schedules as well as

enhance network security and improve the success rate of network maintenance task by ensuring that PC’s

are accessible when IT needs them to be.

The capability of having an on-demand network-wide shutdown protects against virus outbreak or an

imminent power outage. Similarly, shutting down unattended PCs (whether logged onto or not) after

operating hours can help protect against unauthorized access to the PCs’ data or to network resources.

Approximate average annual electric consumption of computer components: PC Only: 120 kWh @ $0.15 per kWh = $18 per year

Monitor Only: 120 – 150 kWh @ $0.15 per kWh = $ 18 – 23 per year

Combined PC and Monitor: 200 kWh @ $0.15 per kWh = $30 per year

The indoor pool has a circulation pump that is sized for 5.05 hours per turnover, whichexceeds the NJ State Sanitary Code of 8 hours per turnover or less.

The pool pump operates at constant speed, 24 hours per day, 365 days per year. Openhours for the pool are approximately: Mon-Fri 7 A.M. - 4:00 P.M.; Hours also varythroughout the year, depending on the school and city’s needs.

By installing a VFD on the pool pump, facilities staff can reduce the pump speed duringunoccupied hours to the minimum flow rate required to meet the state sanitary coderequirements. The existing flow rate can be maintained during occupied hours.

ECM #7: Lighting Upgrade

Although most of the current light fixtures have higher efficiency T-8 fluorescent lamps and ballasts, the 32-watt lamps can be replaced with 28-watt lamps while maintaining the required lighting output as per state codes.

The schools’ gyms have older high intensity discharge (HID) lighting technology which should be retrofitted with High Output T8 fluorescent fixtures.

Furthermore, many areas such as rest rooms and storage closets were observed to have lights on regardless of occupancy. Installing occupancy sensors in these areas will automatically turn lights on/off according to actual occupancy by sensing the presence of people in the room. Occupancy sensors will typically reduce lighting energy costs by approximately 30%*.

ECM #8: Rooftop Unit (RTU) Replacement

The Elementary School has rooftop units (RTUs) that are approximately11 years old and nearing the estimated equipment service life (EESL) perASHRAE standards. (The EESL for package rooftop units is 15 years.)

Replacing these RTU’s with new, higher efficiency units will significantlyreduce annual energy and maintenance costs.

New Jersey SmartStart offers rebates that usually pay for the incrementalcost to upgrade to higher efficient units.

ECM #9: Replace Boilers with Modulating Condensing Boilers

The Firehouse and Library boilers are 36 yrs old and 20 yrs old, respectively.

The Firehouse boiler exceeds the estimated equipment service life per ASHRAE standards and theLibrary boiler is nearing the end of the equipment service life (ASHRAE states the service life of similarequipment is 25 years).

The age and type of existing boilers do not lend themselves to efficient operation. Generally, as boilersapproach the end of their service life, the efficiency degrades and the boiler consumes more fuel inorder to produce the same rated output. In addition, there is a direct correlation between risk ofequipment failure (shell cracks and furnace surface area failure) and equipment age.

If the existing boilers are replaced by high efficiency, modulating condensing boilers, savings will berealized in two ways: Modulating boilers, usually 1,000 MBH or smaller, employ multiple burners to meet the heating load. Each burner

operates independently, eliminating the “all on/all off” operation of single burner boilers. As building loadincreases only those burners necessary to meet the load are fired. This allows each burner to run at optimalefficiency.

Condensing boilers recover energy from the exhaust gas, which results in efficiencies of 90% and above.

When a boiler is both a modulating/modular type and a condensing type, extremely high efficienciescan be realized.

ECM #10: Weather stripping Exterior Doors

Many of the perimeter doors have poor weather stripping, which allows outside air to infiltrate conditioned areas causing an unnecessary increase in the heating, cooling and dehumidification load.

Dome-Tech recommends replacing all old weather stripping on perimeter doors that do not have vestibules.

Energy savings will be realized by reducing the amount of unconditioned outside air to enter the buildings.

ECM #15: Walk-In Cooler Controllers

Typically the walk-in cooler evaporator fans run continuously.

However, full airflow is only required 50% of the runtime.

In the most common applications (those that use single-phase

power), motors for the fans are typically shaded-pole or permanent-

split-capacitor types, both of which are very inefficient.

Inexpensive controllers are currently available that slow these fans

when full-speed operation is unnecessary.

Reducing the operating speed reduces the energy consumption of

the fan. In addition, the motor produces less heat at slower speeds,

which means that the compressor has less heat to remove from the

refrigerated compartment.

A garage bay door replacement project would result in a measurable improvement in

heat retention. In addition, increased aesthetic value and occupant comfort would

accompany a window and door project. It should be noted however, that even a garage

Because the economics alone are not sufficient to justify implementation, occupant

comfort and aesthetics should be the overriding considerations in deciding whether to

move forward with this project.

A building management system (BMS) is a computer system designed specifically for the automatedcontrol and monitoring of the heating, ventilation and lighting systems for a single facility or group ofbuildings. The BMS can also be used for data collection and used to produce trend analyses and annualconsumption forecasts.

This facility has a controller-based centralized energy management system. However, the HVACsystems are currently being operated manually. The energy management system has limited capabilityto allow building personnel to operate the HVAC systems in a more efficient manner.

Due to the limitations of the current controls system, Dome-Tech recommends installing a computerbased Building Management System that will enable the following strategies to be implemented:

ECM #21A: Demand Controlled Ventilation

Building codes require that a minimum amount of fresh air be provided to ensure adequate air quality. To

comply, ventilation systems often operate at a fixed rate based on an assumed occupancy (e.g., 20 CFM

per person multiplied by the maximum design occupancy). Since maximum design occupancy is rarely

achieved, this results in excessive fresh air volumes which require costly and unnecessary conditioning.

Demand-controlled ventilation (DCV) controls the amount of outside air being supplied based upon the

CO2 levels generated by building occupants. DCV should be added to any space that is ventilated by a

large quantity of outdoor air, and where occupancy varies dramatically (gymnasiums).

Because CO2 levels correlate directly with the number of people in an occupied zone, CO2 sensors will

be used to control the amount of outside air supplied to each zone. Reducing the amount of outdoor air

supplied to a zone reduces the energy required to heat and cool the air, while space conditions are kept

in compliance with building codes and standards such as the ASHRAE Indoor Air Quality Standard.

ECM #21B: Optimize and Standardize the Space Temperature Setpoints

In the Elementary School, the current space temperature setpoints were inconsistent

and ranged between 73-76°F.

A majority of the Unit Ventilators (UV’s) and RTUs have higher than recommended

heating setpoints, which results in higher than expected heating costs.

Dome-Tech recommends optimizing the HVAC setpoints according to the table on the

following page.

ECM #21C: Holiday Time of Day Optimization

A review of the BMS time of day schedules revealed that no holiday schedulesare programmed.

Unless each facility manually shuts down all the HVAC equipment, they areoperating unnecessarily during school holidays. This increases HVACconditioning costs as well as electrical motor operating costs.

These savings can easily be achieved by programming the BMS holidayschedules to unoccupied mode and applying it to holidays in the BMS.

Water Conservation

Dome-Tech recommends installing low flow faucets and waterless urinals in all restrooms. Thesefixtures, in some cases, can use up to five (5) times less water than fixtures installed before 1980.

Waterless urinals work completely free of water or flush valves and help eliminate odor. The fixtures arealso touch free which also help to improve restroom sanitation.

The estimated annual savings will result from reduced water consumption and hot water generated bythe domestic hot water heaters.

Renewable/Distributed Energy Measures

Distributed Generation & Renewable Energy

Distributed Generation (on-site generation) generates electricity from many small energy sources. These sources can be renewable (solar/wind/geothermal) or can be small scale power generation technologies (CHP, fuel cells, microturbines)

Renewable energy is energy generated from natural resources (sunlight, wind, and underground geothermal heat) which are naturally replenished.

Renewable Energy Technologies: Wind

Wind turbines generate electricity by harnessing a wind stream's kinetic energy as it spins the turbine airfoils. As with most renewable energy sources, wind

energy is subject to intermittent performance due to the unpredictability of wind resources.

City of Cape May Wind Speed

Wind speed is critical to the successful wind turbine installation. According to average wind data from NASA’s Surface Meteorology and Solar Energy

records, the average annual wind speed for the Cape May area is 9.6 meters per second. Ideal wind speeds for a successful project should average over 6

meters per second.

For City of Cape May, Dome-Tech considered three (3) types of wind turbine technologies; building integrated wind turbines (1 kW each) and traditional

ground mounted wind turbines (5 kW & 50 kW).

Renewable Energy Technologies: Solar Photovoltaic

Solar Photovoltaic

Sunlight can be converted into electricity using photovoltaic's (PV).

A solar cell or photovoltaic cell is a device that converts sunlight directly into electricity.

Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon. Electrons are knocked loose from their atoms, allowing them to flow through the material to produce electricity.

Solar cells are often electrically connected and encapsulated as a module, in series, creating an additive voltage. The modules are connected in an array. The power output of an array is measured in watts or kilowatts, and typical energy needs are measured in kilowatt-hours.

The Public Works building currently has an inactive solar PV system. As we understand it, the system’s annual output is greater than what the building consumes and therefore, it does not comply with the utility’s net-metering rules. Dome-Tech recommends considering tying the PV system at the Public Works building into the Water Works Building. Note: The City of Cape May should consider all potential utility regulations before proceeding.

Potential Sites for recommended for further study:

This allows the City the opportunity to not only

gain experience with this energy technology,

but also to win recognition as an

environmentally sensitive, socially conscience

institution. Additionally, these projects could

be incorporated into science education and

additional curriculums to raise awareness of

current energy alternatives to the younger

generations.

Renewable Energy Technologies: CHP/Cogeneration

CHP (combined heat and power) or cogeneration is the use of a heat engine to simultaneously generate both electricity and useful heat.

Fuel Cells are electrochemical conversion devices that operate by catalysis, separation the protons and the electrons of the reactant fuel, and forcing the electrons to travel through a circuit to produce electricity. The catalyst is typically a platinum group metal or alloy. Another catalytic process takes the electrons back in, combining them with the protons and oxidant, producing waste products (usually water and carbon dioxide).

Microturbines are rotary engines that extract energy from a flow of combustion gas. They can be used with absorption chillers to provide cooling through waste heat rather than electricity. Microturbines are

best suited for facilities with year-round thermal and/or cooling loads.

Not recommended for Cap May City due to a lack of a continuous year-round thermal load.

Utility Tariff and Rate Review: Electricity

Accounts and Rate Class: City of Cape May has thirteen electric accounts with service

behind Atlantic City Electric Company under rate classes Monthly General Service and Annual

General Service.

Electric Consumption and Cost: Based on the one-year period studied, the total annual

electric expenditure for the City is about $487,000 and the total annual consumption is about

2,560,330 kilowatt-hours (kWh).

Average/Effective Rate per kWh: For the one year period studied, the City’s average

monthly cost per kilowatt-hour ranged from 16.07 ¢/kWh to 22.43 ¢/kWh, inclusive of utility

delivery charges. The City’s overall, average cost per kilowatt-hour during this period was

19.03 ¢/kWh.

o Note that these average electric rates are “all–inclusive”; that is, they include all supply service

(generation and commodity-related) charges, as well as all delivery service charges. The supply

service charges typically represent the majority (60-80%) of the total monthly bill. It is the supply

portion of your bill that is deregulated, which is discussed on subsequent slides in this section.

Utility Tariff and Rate Review: Natural Gas

Accounts and Rate Class: City of Cape May has twelve natural gas accounts with service

behind South Jersey Gas Company under unknown rate classes most likely being Monthly

and Periodic Service (the rate class could not be determined due to missing SJGAS bills).

Natural Gas Consumption and Cost: Based on the one-year period studied, the total

annual natural gas expenditure for the City is about $124,000 and the total annual

consumption is about 67,000 therms (th). Natural gas is used predominantly throughout the

winter period for heating purposes.

Average/Effective Rate per Therm: For the one year period studied, the City’s overall,

average cost per therm during this period was $1.900 per therm.

o Note that these average natural gas rates are “all–inclusive”; that is, they include all supply service

(interstate transportation and commodity-related) charges, as well as all delivery service charges. The

supply service charges typically represent the majority (60-80%) of the total monthly bill. It is the supply

portion of your bill that is deregulated, which is discussed on subsequent slides in this section.

Utility Deregulation in New Jersey: Background and Retail Energy Purchasing

In August 2003, per the Electric Discount and Energy Competition Act [N.J.S.A 48:3-49], the

State of New Jersey deregulated its electric marketplace thus making it possible for customers

to shop for a third-party (someone other than the utility) supplier of retail electricity.

Per this process, every single electric account for every customer in New Jersey was placed

into one of two categories: BGS-FP or BGS-CIEP. BGS-FP stands for Basic Generation

Service-Fixed Price; BGS-CIEP stands for Basic Generation Service-Commercial and

Industrial Energy Pricing.

At its first pass, this categorization of accounts was based on rate class. The largest electric

accounts in the State (those served under a Primary or a Transmission-level rate class) were

moved into BGS-CIEP pricing. All other accounts (the vast majority of accounts in the State of

New Jersey, including residential) were placed in the BGS-FP category, receiving default

electric supply service from the utility.

The New Jersey Board of Public Utilities (NJBPU) has continued to move new large energy

users from the BGS-FP category into the BGS-CIEP category by lowering the demand (kW)

threshold for electric accounts receiving Secondary service. Several years ago, this threshold

started at 1,500kW; now, it has come down to 1,000 kW. So, if an account’s “peak load share”

(as assigned by the utility) is less than 1,000 kW, then that facility/account is in the BGS-FP

category. If you are unsure, you may contact Dome-tech for assistance.

Utility Deregulation in New Jersey: Background and Retail Energy Purchasing (cont.)

There are at least 3 important differentiating factors to note about each rate category:

1. The rate structure for BGS-FP accounts and for BGS-CIEP accounts varies.

2. The “do-nothing” option (ie, what happens when you don’t shop for retail energy) varies.

3. The decision about whether, and why, to shop for a retail provider varies.

Secondary (small to medium) Electric Accounts:

o BGS-FP rate schedules for all utilities are set, and re-set, each year. Per the results of our State’s BGS

Auction process, held each February, new utility default rates go into effect every year on June 1st. The

BGS-FP rates become each customer’s default rates, and they dictate a customer’s “Price to Compare”

(benchmark) for shopping purposes. To learn more about the BGS Auction process, please go to

www.bgs-auction.com.

o A customer’s decision about whether to buy energy from a retail energy supplier is, therefore, dependent

upon whether a supplier can offer rates that are lower than the utility’s (default) Price to Compare. In

2009, and for the first time in several years, many BGS-FP customers have “switched” from the utility to

a retail energy supplier because there have been savings. This may be the same case in 2010.

Primary (large) Electric Accounts:

o The BGS-CIEP category is quite different. There are two main features to note about BGS-CIEP

accounts that do not switch to a retail supplier for service. The first is that they pay an hourly market

rate for energy; the second is that these accounts also pay a “retail margin adder” of $0.0053/kWh. For

these large accounts, this retail adder can amount to tens of thousands of dollars. The adder is

eliminated when a customer switches to a retail supplier for service.

o For BGS-CIEP accounts, the retail adder makes a customer’s decision about whether to switch

relatively simple. However, the process of setting forth a buying strategy can be complex, which is why

many public entities seek professional assistance when shopping for energy.

Utility Deregulation in New Jersey: Background and Retail Energy Purchasing (cont.)

Natural Gas Accounts:

o The natural gas market in New Jersey is also deregulated. Unlike the electric market, there are no

“penalties”, or “adders”, for not shopping for natural gas. Most customers that remain with the utility for

natural gas service pay rates that are market-based and that fluctuate on a monthly basis. While natural

gas is a commodity that is exceptionally volatile and that is traded minute-by-minute during open trading

sessions, market rates are “settled” each month, 3 business days prior to the subsequent month (this is

called the “prompt month”). Customers that do not shop for a natural gas supplier will typically pay this

monthly settlement rate to the utility, plus other costs that are necessary to bring gas from Louisiana up

to New Jersey and ultimately to your facility.

o For additional information about natural gas trading and current market futures rates for various

commodities, you can refer to www.nymex.com.

o A customer’s decision about whether to buy natural gas from a retail supplier is typically dependent

upon whether a customer seeks budget certainty and/or longer-term rate stability. Customers can

secure longer-term fixed prices by enlisting a retail natural gas supplier. Many larger natural gas

customers also seek the assistance of a professional consultant to assist in their procurement process.

Retail Energy Purchasing: Recommendations and Resources

Electric

o Based on current and recent market conditions, and actual bid processes run by Dome-Tech for various

clients during 2010, we have seen customers with BGS-FP accounts save approximately 10-15% in

projected energy costs by switching to retail energy supplier. It is important to note that actual rates and

potential savings will be dependent on several factors, including market conditions, account usage

characteristics/load profile (load factor), volume, and contract term.

Natural Gas

o Based on current and recent market conditions, and actual bid processes run by Dome-Tech for various

clients during 2010, we have seen many customers entering into longer-term contracts for fixed natural

gas rates. These rates vary substantially based on load type, volume, and term.

Energy Purchasing Co-Operatives

Many public entities participate in various energy aggregation buying groups. Sometimes, an entity will

have multiple options to choose from. These might include purchasing through a County co-operative,

or purchasing through a trade-type association. Co-operative purchasing may not necessarily get you

the lowest rates; however, there is often substantial volume, and it can represent a good alternative for

entities with limited energy consumption who can have a difficult time getting energy suppliers to

respond to them on a direct, singular basis.

To determine whether a savings opportunity currently exists for your entity, or for guidance on how to get

started, you may contact Dome-Tech to discuss. There is also additional information provided below.

Retail Energy Purchasing: Next Steps

Electric

For the period studied, the City was utilizing a Third Party Supplier for the supply of electricity to their

BGS-FP account. The City’s electric accounts are part of the South Jersey Power Co-Operative’s

existing contract with Hess Corporation. The contract term is until September 2011 at the fixed rate of

$0.09147 per kWh.

Natural Gas

For the period studied, the City was utilizing a Third Party Supplier for the supply of natural gas to

their SJGAS accounts. The City’s gas accounts are part of the South Jersey Power Co-Operative’s

existing contract with Woodruff Energy. The contract term is until December 2011 at the fixed rate of

$1.0815 per therm.

Dome-Tech recommends the City continue to participate in the SJPC purchasing group for electricity
