A Look at the Complexities of Energy Load Forecasting
Dianoush Emami has a background in electrical engineering, including extensive experience in the design and implementation of safety protocols and programs at power plants. Over the course of his career, Dianoush Emami has guided diverse geotechnical and structural elements for projects spanning power and water facilities, including the measurement and forecasting of electricity loads.
The complexity of electricity load forecasting reflects the variety of generating units and their associated production capacities. Because it is difficult to store electricity, generation must meet consumption demands in real time to be profitable. “Electricity load” describes the direct relationship between electricity demand and electricity generation costs.
Owners of generated electricity assets require an accurate forecast of expected load demands within specific markets. This is undertaken across forecast horizons ranging from as little as a single hour to a week or more. Factors taken into consideration include weather, season, day of week, and time. Accurate load forecasts require complex, nonlinear modeling of load-weather and other relationships.

Construction at Vogtle Power Plant Brings Jobs and Power
The recipient of a bachelor of science in electrical engineering (BSEE) from the University of Southern California, Dianoush Emami has led dozens of engineering projects for companies such as Bechtel Power Corporation over his long career. Among other notable projects, Dianoush Emami worked on specification administration for transformers, inverters, and other contracts at the Alvin F. Vogtle nuclear power plant in Waynesboro, Georgia.
Construction on the Vogtle Electric Generating Plant began in 1974, with the first unit coming online in 1987 and a second unit opening in 1989. After nearly 20 years of service, officials determined that the plant was no longer adequate for the state’s power needs and approved a two-unit expansion in 2006. Construction on the two new units, which represented the first new nuclear construction in nearly thirty years, began in 2013 and is expected to be completed by 2020.
The new units will provide much-needed capacity to the plant and, once finished, will generate enough energy to power a half-million homes and businesses in the state. In addition to increased power production, the new construction at the Vogtle Electric Generating Plant will bring multiple benefits to the community. For example, the construction process has added more than 6,000 jobs in the area, with 800 of these positions transitioning into permanent roles once construction is completed.

Vogtle Nuclear Plant Powers Georgians’ Lives for Three Decades
Since graduating from the University of Southern California with a degree in electrical engineering, Dianoush Emami has amassed a range of professional certifications in his field. Over the past almost 40 years, the electrical engineer has brought an emphasis on safety, quality, and compliance to multiple projects for the utility industry. Among Dianoush Emami’s largest-scale efforts is his work on the Alvin W. Vogtle Nuclear Power Plant.
Mr. Emami handled the administration of technical specifications for this project, located in Waynesboro, Georgia, close to the state’s border with South Carolina. The plant was named for a prominent executive in the electrical industry.
The initial construction activity on the original two-unit Vogtle plant began in 1974, with its first unit becoming operational in 1987. The second of the units followed two years later. The Westinghouse Electric Company manufactured the plant’s pressurized water reactors.
Today, the combined power of the Vogtle plant is able to generate more than 2,400 megawatts, enough power to support half a million homes and businesses. The plant employs some 900 people.
Situated in a rural area that is home to a wide range of flora and fauna, the Vogtle plant has been certified as a Wildlife Habitat Council site for 25 years. Hundreds of acres in the plant’s vicinity have been replanted with native evergreen species, and its management has participated in local programs designed to educate the public about environmental issues.
In 2009, the plant received a 20-year extension to its operating license.

RTUs and IEDs - Essential Components of a SCADA System
With almost four decades of experience as an electrical distribution and transmission high-voltage engineer, Dianoush Emami has enhanced the efficiency and performance of high-voltage electrical transmission equipment, components, and systems. During his career, Dianoush Emami created four task forces, one of which addressed remote terminal unit (RTU) and intelligent electronic device (IED) data exchange.
Supervisory control and data acquisition (SCADA) systems collect data and control large-scale systems by monitoring network functions at the supervisory level. They can regulate a process, or control machinery. RTUs and IEDs are two components of a SCADA system that perform monitoring and controlling functions.
An RTU is most often used in industrial environments for remote monitoring and control of automated devices and systems. A self-contained computer, an RTU has a processor, memory, and storage. It is intelligent enough to control multiple processes without user intervention or a master controller. This allows an RTU to send telemetry data to distributed control systems (DCS) and SCADA systems. RTUs monitor equipment within the SCADA system, including IEDs.
An IED creates communication between remote sensors and controllers and a communications network. It can control many parts of a piece of equipment so the equipment works in accord with the rest of a system. It also gathers information from power equipment within the SCADA system. For example, if an IED senses a certain level, such as voltage, is too high or low, it can initiate a control function to correct the level back within normal limits.

A Look at the California ISO’s Market Processes and Products
Dianoush Emami is a graduate of the University of Southern California and has served as a safety professional for nearly forty years. The former director of WESCON, Dianoush Emami has emerged as a leader in the safety industry due to the scope and quality of his work.
For example, Mr. Emami completed a technical audit for the California Independent System Operator (CAISO) that involved a review of the generation control systems for the state of California. An independent electrical grid operator, CAISO manages the flow and distribution of electricity across California’s electrical grid.
CAISO also operates a wholesale energy market that includes five core service offerings. In addition to a day-ahead market in which energy is distributed based on a bidding system, the organization manages a real-time market that allows utilities to purchase power to cover electrical shortages not met by bids placed in the day-ahead market.
CAISO also offers ancillary services to maintain grid stability, and financial instruments known as congestion revenue rights (CRRs) that allow utilities to address grid congestion costs. Moreover, participants in the electrical market can engage in convergence bidding through CAISO. Convergence bidding allows energy to be bought in the day-ahead market and sold in the real-time market.
