San Diego Gas & Electric Southern California Gas Sempra Generation Sempra Pipelines & Storage Sempra LNG RBS Sempra Commodities* Infrastructure & Marketing Electric & Gas Utilities Est. 1867 Est. 1881 Sempra Energy was formed in 1998 from a merger between Pacific Enterprises (parent of Southern California Gas Company – SoCal Gas) and Enova Corporation (parent of San Diego Gas and Electric – SDG&E). Even though the Sempra Energy brand is relatively new, its core power and gas businesses have more than 120 years of history. Sempra Energy has 13,500 employees worldwide and more than 29 million consumers worldwide. The Sempra Energy companies develop energy infrastructure, operate utilities and provide related products and services. Sempra Energy's regulated utilities, San Diego Gas & Electric and Southern California Gas Company serve California customers from the state's Central Valley to the Mexican border. In the last 10 years, Sempra has grown from the traditional power and gas distribution companies to an integrated energy business consist of four additional business units. Sempra Liquefied Natural Gas (LNG) Sempra Pipelines & Storage Including power & gas distribution companies in Argentina, Chile, Peru, and Mexico Sempra Generation Sempra Commodities (became RBS Sempra Commodities April 2008) * Sempra’s ownership interest is 49% 2

Sempra LNG is working to bring natural gas to North America to meet the growing demand. Natural gas is abundant in other parts of the world. That gas can be supercooled so it turns into a portable liquid, and then shipped to Sempra LNG’s receipt terminals in North America. There the LNG is turned back into gas and sent to market. Energia Costa Azul (Completion May 2008) The terminal is fully contracted and capable of processing 1 billion cubic feet per day (Bcf/d) of natural gas, with room for expansion. While Sempra LNG owns 100 percent of the facility, the company is leasing half of Energía Costa Azul's processing capacity to Shell International Gas Limited under a 20-year agreement. Sempra LNG's half of the capacity at Energía Costa Azul will be supplied from a new liquefaction facility nearing completion at Tangguh, Indonesia. Shipments from the Indonesian facility should begin arriving in the second quarter of 2009. Cameron LNG On the Calcasieu Channel, 18 miles from the Gulf of Mexico in Hackberry, La. Owned 100 percent by Sempra Energy; represents a capital investment of about US$750M. 1.5 billion cubic feet per day of initial send out capacity, with room for expansion.

PI serves the day to day planning, monitoring, operational, and maintenance needs of these specific business units. PI was first adopted in the power generation business units. It was implemented in SDG&E for Power Transmission and Distribution about five years ago. Later PI was deployed in Gas Storage Facilities in SoCal Gas in the West coast , merchant Gas Storage Projects in the Southwest, and most recently deployed in the LNG terminals. PI will also be implemented in our renewable power generation projects. 10

11 Sempra Energy PI Examples

12 T&D System Operations System Operating Diagram
This is an example of PI application in electric substation & distribution. This integrated one-line diagram provides both key transmission and distribution operating data which improves the coordination between the transmission operating center and the distribution operating center. Operators can quickly determine a substation outage by the T&D circuit breaker status and notify substation personnel to respond quickly. Substation personnel also has real-time access to this diagram to support outage restoration, planning, operations, and equipment maintenance. 12

13 Distribution Planning
Potential Overload Watch List Distribution Planning engineers are able to monitor and report on highly loaded circuits with potential overload. This tool allows the engineer to manage the circuit loading proactively before an overload alarm is triggered. The engineer has the option to cut over distribution branches through switching to balance circuit loading in the distribution network or initiate temporary equipment upgrade. 13

14 Emergency Operations Rolling Blackout/Load Curtailment
This application allows the personnel in the Emergency Operating Center to manage a load curtailment event (a proactive rolling outage program directed by the California Independent System Operator to restore the operating reserve to above 5%). The distribution circuits are listed in order of the load curtailment sequence. The personnel can group the circuits quickly, select the total load requirement, and initiate an automatic action to open these circuits. Additional groups can also be selected anticipating the curtailment for the next hour. With this tool, each load curtailment request can be fully executed in minutes. 14

15 Dynamic Transmission Rating
OH Transmission Dynamic Rating vs. Static Rating • Ruling span concept Load Cells for measuring cable tension • Cable Tension (CAT) Monitoring Unit • Radio transmitter 230KV UG Cable • Fiber optic sensors Real-time modeling Dynamic rating With this monitoring tool, the transmission operator can make real time decision on the operating limit of the transmission segment. In overhead transmission, it consist of a wire tension monitoring unit, an Remote Terminal Unit with weather monitoring, and a communication link. In underground transmission XLPE cable, the fiber optic temperature sensors is embedded in the cable jacket. The traditional conductor thermal limits were built with safety factors. This real-time monitoring tool has shown that the dynamic rating of the line segment is always above the emergency rating. This information allows the operators addition options in managing a transmission network and to maximize the capability of existing transmission lines. 15

Comparison of hot spot rise over top oil simulated versus actual Top Oil Hot Spot LOL IEEE Ptload Actual HS rise Decision: Based on Transformer Unit Health and Real Time Conditions Also with available historical, routine, and real-time data, the engineer can predict the dynamic rating of the transformer by running loading simulation using IEEE or Ptload software. 20

21 CBM PI Notifications Email Alert
One of the key application of PI – Real-time Alerts It allows the substation personnel and operators to setup lower priority alerts. Personnel can receive s and text messages or these alerts. These non-critical alerts would allow scheduling of maintenance activities. It also provide early warning system to the operator so that emergency plan could be created in the event of an equipment failure. 21

22 CCGT Plant Operations This is an example of a PI display for monitoring a combined cycle power plant. It gives a quick summary of the plant’s operating status: Turbine output Turbine vibration Boiler feed pumps Cooling system Units and ambient temperature Control communication status 22

The PLC communicate in MODBUS via a fiber connection to the control room. Data from on-site pyranometers and weather station input are collected via the PLC. The PI server collects data via the SCADA interface and provides remote data access. Additional weather forecast data are loaded in the central PI database which provides user application for solar forecasting & scheduling. Solar Data Access 28

29 Solar Field Monitoring
Performance Monitoring DC and AC Output Inverter Operating Conditions Weather Conditions Solar field monitoring is very critical because the performance of solar panels and inverters are very sensitive to the operating temperature. The PI display will consist of total system DC and AC output. Operating and performance data from the 20 intelligent inverters are accessible. By comparing the performance of these 20 inverters, performance and degradation of solar panels and inverter can be measured against manufacturer specifications. Through continuous monitoring, Sempra Generation will gain additional operating experience of dust (fouling) effects on solar panels’ performance and will determine a washing schedule based on economics. 29

31 Solar Generation Applications
Irradiance Analysis (Historical, Predicted, and Actual) National Renewable Energy Lab (NREL) Typical Meteorological Year (TMY) TMY2 and TMY3 Data Sets Statistical Modeling Solar output forecasting is a challenging activity. Hourly historical solar irradiance data is available for about 30 years, the information is primarily applicable for statistical annual output forecast. In order to produce day-ahead forecast, the output data from the most recent days and a hourly weather forecast for cloud coverage and cloud ceiling are required. Even with these data, the day-ahead forecast is an attempt to provide a best estimate of the daily output only. The hour to hour and intra-hour output fluctuation due to cloud and other weather conditions will require additional equipment and modeling. 31
