To install a networked power trend management system (hereafter called the “PTM system”) in the client’s facility in order to lower the peak power demand at the main load panel, and to provide energy usage data that may be used to reconcile the utility energy charges and wire demand charges. Olson Power Trend Management Inc. shall design, build, and provide the PTM system equipment and all necessary software and firmware to make the system perform as described herein. The client shall participate in the validation and verification testing at each milestone defined herein, and upon the successful conclusion of each milestone test shall make the agreed milestone payment. The client shall provide specified items described in the section “Site Requirements.” 2. Expected Performance of the System The proposed system is an installed networked monitoring and control system aimed at reducing peak power demands at the main power panel. 2.1. The system shall use intelligent electronic devices (IED) located at each load relay to sense and measure the load current and load operating statistics. The measurement information shall be stored and forwarded by means of local MODBUS data communication to a central controller (PLC). 2.2. The PLC shall constantly monitor electrical loading and unloading activity and look for ways to reduce peak demands by preventing simultaneous start-up loading. This shall be done by applying short delays to certain load starts, and by avoiding short power-off periods for other loads. 2.3. If at times the aforementioned prevention of simultaneous loading is not possible, the system shall immediately generate a report for the system supervisor and indicate that the desired power limit was exceeded. 2.4. The system shall not be used to reduce or restrict the energy usage within the facility. 2.5. There shall be user-adjustable parameters to allow optimisation of cost reduction and “business as usual” operation of electrical equipment in the facility. 2.6. There is no guarantee of specific cost reduction or specific reduction in peak demands. Such outcomes depend upon subjective assessments at the conclusion of the commissioning phase. 2.7. There is no guarantee of meeting a specified time for cost recovery for beta test clients. 3. Proposed System Network Architecture The following clauses are illustrated by Figure 1.
3.1. The IED (load monitor devices) shall be multi-dropped throughout the facility. 3.2. There shall be one IED for each branch load to be monitored, plus one IED at the main electrical panel. The number of IEDs can be increased at any time with a proportional increase in the unit cost price extensions. 3.3. The master control PLC shall perform all the data scanning and power trend control functions. 3.4. The host PC shall provide the management functions such as sending alarms, data historian, report generation, system and load fault reporting, and power trend graphs. 3.5. The PLC shall continue to function if the PC host is not operational. 3.6. The IEDs shall continue to function, but in a reduced capacity, if the PLC is not operational. 3.7. PLC and IED failures shall be reported by the PC host. 4.1. The system shall provide a means by which facility management can set a reasonable limit to the peak power demand at the main electrical panel. This limit shall be a “goal” for the system to try to reach. 4.2. The system shall prevent peak power draw from exceeding the defined demand limit (goal) by calculating and applying a precise time delay for the activation of loads that have their own load relays. The intent of the delay is to allow a few seconds for other load activity to complete its peak cycle. If no other peak loading cycle is currently under way, no delay is applied. 4.3. At the option of the user, the IED shall delay start-up of the attached load if the load would otherwise be started too many times within a set period. This shall aid in the reduction of peak power draw by reducing the number of start-up surges per day. 4.4. At the option of the user, the IED shall prevent shut-down of the attached load if the load would otherwise be started too many times within a set period. This shall aid in the reduction of peak power draw by keeping certain large loads powered on constantly as opposed to cycling them off and on, and only as long as it is statistically favourable for cost reduction. Note: clause 6.3 and 6.4 are mutually exclusive. The user must set each IED to work in one of these modes only. The IED can be set to do neither, in which case it shall function purely a power meter and load protection device. 4.5. The system shall allow the load to be energised if the imposed delays exceed reasonable time limits. In other words, do not interfere with business as usual, and do report unavoidable excursions in peak demand. 4.6. The system shall advise facility management if and when any of the load equipment’s normal operational parameters are being exceeded as a result of abnormal circuit conditions or decreases in efficiency of the loads being monitored. (For example, bearing failures or drive belt failures.) 5. Effects Upon Normal Operations Some users may experience the following effects: 5.1. During times of peak electrical draw users may on occasion experience a delay when they choose to turn on large branches of lighting fixtures. 5.2. Users should expect short but noticeable delays and be advised to be patient for a few seconds. 6.1. Demand Power for the facility shall be calculated and stored for reconciling against the utility company’s invoice. 6.2. Total energy draw shall be calculated and stored for reconciling against the utility company’s invoice. 6.3. Loads shall be monitored for abnormalities in their electrical characteristics. 6.4. Each IED shall protect its associated load from the following electrical faults:
6.5. A load trend report shall be available to management. 6.6. When there is enough data to predict an imminent load failure an alarm shall be generated by the host PC. 6.7. Daily, weekly, and monthly trends shall show when and where peaks are being set within the facility. 6.8. It shall be possible to view the real-time current and voltage on the IED’s local data display. 7. System Maintenance Requirements 7.1. The heart of the system shall consist of one Pentium PC and one programmable logic controller (PLC). 7.2. It shall be that the PC can be stopped without interrupting the power trend management functions in the PLC. 7.3. It shall be that the PLC can be stopped without interrupting the load protection and data gathering functions of each load monitor (IED). 7.4. An optical disc may be used for periodic storage of history data. A person under the employ of the client must be assigned to the task of loading and unloading the backup discs. 7.5. There shall be no requirement for prerequisite technical training and expertise. 7.6. The PTM system shall come with a complete set of user documentation on CD-ROM. 7.7. The user documentation shall be loaded onto the PC and shall be accessible through normal user menu selections while also running the system reports and control applications. 7.8. The user manuals shall include up-to-date example pictures to guide the users through each procedure. 7.9. The PC and the network shall be initially sized to handle 100% expansion in the number of load monitors (IED) without changes to hardware, except for the added load monitor devices and their associated wiring. The client agrees to make the following provisions for the system. 8.1. A normal office environment is required for locating the host PC. 8.2. Network cabling shall be installed at the client’s expense. 8.3. A bridging device shall be located near the bulk of the load monitors. 8.4. Shielded twisted pair cable shall be used to connect all the load monitor devices with the controller PLC and host PC. If existing trays and conduit cannot accommodate the data cable the client shall be responsible for making alternate arrangements. 8.5. The load monitors shall be wall mounted near each existing load relay. There must be adequate space for mounting the IED within 1 metre of the load relay. 8.6. There must be sufficient space for the current sensors to be placed around each AC conductor for the load and to be anchored to the nearest vertical surface. 8.7. If it becomes necessary to remove load conductor connections in order to attach the current sensors, the cost of disconnecting and reconnecting the load wire shall be at the client’s expense. 8.8. Each IED shall require a normal 120 volt AC outlet within 1.5 metres of where the IED will be mounted. 8.9. Loads that only need to be monitored shall not require a load relay. 8.10. If it becomes desirable to intervene in the operation of a load that has no relay, a relay shall be added by a licensed journeyman as a separate consideration at the client’s expense. The existing load monitor and the network system will require some changes to their operating configuration, and such changes related to adding a load relay shall be at the client’s expense. 8.11. The main power panel shall require a main line load monitor, connected on the load side of the utility meters. This is where the total facility electrical load will be monitored. The following table defines the equipment and services to be provided by the vendor for a small installation that requires only seven IEDs.
9.1. The actual system size and start date is chosen to suit the client’s needs and preferences. 9.2. The milestone dates are estimations only. The milestone payment shall be due when the milestone objectives have been achieved. 9.3. All prices are subject to revision at any time. Please contact Olson Power Trend Management Inc. for a formal quotation. 9.4. The client agrees to make each milestone payment upon seeing satisfactory proof of each milestone being achieved. 9.5. The client may optionally have their own technical representative present during critical testing, as long as it is at the client’s expense. 9.6. The client shall sign a test plan and associated test report as an indication of acceptance of the test results for each milestone and this shall be considered proof of client acceptance. 9.7. Shipping to the client site is at the cost of the client. All prices are F.O.B. Calgary Alberta, Canada. 9.8. The PTM system shall be fully programmed and all variable data entered by the vendor. 9.9.

10.9. The client can request the following options to be installed with the system as separate considerations at extra cost:
10.10. The client shall be permitted to request additional load monitor IED units during the commissioning phase, or after the final acceptance. The per unit base cost shall be $525 CDN plus installation time and materials (cable and connectors) at the same rate as shown in the pricing table. 10.11. If a load fault is detected the IED will prevent closure of the power relay at the load until the IED is reset by action of turning the reset key switch. 10.12. For 99% of all IED failure modes the IED shall make itself transparent to the load and shall thus allow the load to be operated normally. 10.13. The IED will have an internal battery for preventing loss of operating mode data in memory due to loss of primary power (AC). This battery shall sustain the IED memory for five years under normal conditions; no more than 30 minutes of primary power loss per year, cumulative. 10.14. Primary power off/on cycles shall not cause an IED to reset its internal operating mode settings. 10.15. Operating settings shall be reset and modified by the PC host. 10.16. Turning the reset key shall cause the IED to reset all internal error latches and run its diagnostics. The reset key shall not cause a change in operating mode. Run-time power and energy accumulators will not be reset by the key. 11. Warranty and Post-Sales Support 11.1. This agreement defines “warranty” as being system “support” coverage for a limited time following successful commissioning, and such coverage being paid for as part of the overall agreed price of the beta-test system. 11.2. This agreement defines “support” as follows:
11.3. The vendor shall provide the defined support of the system for a period one year from the date of final acceptance. 11.4.
