Northern California Power Agency’s Lodi Energy Center
Northern California Power Agency’s Lodi Energy Center will be the First Fast Start
Combined Cycle Power Plant in the U.S.A. in commercial operation. Based on the
Siemens Flex-PlantTM 30 concept Lodi Energy Center is designed to meet the needs of
the end user, including efficiency, flexibility and a small environmental footprint. The new
plant with an installed capacity of 300 megawatts (MW) will serve the energy needs of
13 different project participants, including Modesto Irrigation District, Power and Water
Resources Pooling Authority, Plumas-Sierra Rural Electric, State of California
Department of Water Resources, Bay Area Rapid Transit, City of Ukiah, City of Lodi,

Optimizing the energy mix for clean reliability generation
Renewable power is becoming a larger and larger part of the energy mix worldwide.
California is a leader in this trend, adding significant amounts of wind and solar capacity
to the grid. These renewable, green resources are environmentally friendly, but are
intermittent due to their dependence on immediate local environmental conditions.
Power today is primarily provided by power plants designed for base load, and lacking
the ability to quickly start up or quickly change load. Fast Moving Flex-Plants are

designed to provide clean, efficient power on demand. Flex-Plants bridge the gap to
enable a stable reliable power generation grid while renewables ramp in and out.
In addition to providing grid stability, the fast start of the gas turbine enabled by the
Siemens Flex-Plant 30 results in a significant reduction in overall plant startup emissions.

Northern California Power Agency Siemens Power Island 1x1 Flex Plant 30
Lodi Energy Center is a Siemens SCC6-5000F 1x1 Flex-Plant - a fast responding, clean,
efficient combined cycle power plant to partner with California’s large non-dispatchable
renewable generation. It is a highly efficient combined cycle plant with an operating
efficiency of over 57 percent designed for intermediate to continuous duty and capable
of daily cycling. Plant start-up times are reduced by up to 50 percent due to the
integration of fast-start features, including the three-pressure reheat heat recovery steam
generator (HRSG) with Benson® once-through technology, high capacity steam
attemperation, full capacity steam bypass systems, innovative piping warm-up
strategies, and Siemens’ steam turbine stress controller (TSC). Using the Siemens
SGT6-5000F gas turbine as the prime mover, the plant will provide high power density
while requiring a relatively small plant footprint. The Siemens SPPA-T3000 control
system provides an easy-to-use control platform for the entire combined cycle power
plant. Its fast start capability with 200 MW in 30 Minutes or less can result in a carbon
monoxide reduction of over 200 tons per year when compared to traditional F-class
combined cycle plants.

Safety at Lodi
At Siemens, safety is considered the most important aspect of every project. In
partnership with NCPA, Siemens followed a detailed safety program for the site.
Siemens Project Manager and Project Engineer independently conducted and
documented a formal site Safety Walk at every site visit. There were also regular site
audits to assure adherence to Siemens and site procedures and prompt action and
resolution for any quality incident reports. This focus on safety resulted in an impressive
Zero Lost Time Accidents (LTA) for OEM or its subcontractor personnel with over 16,000
man-hours on site.

Integration
Having the OEM as an integral part of the Lodi construction management team
enhanced the integration of equipment into the site execution. System integration is a
big part of every Siemens project from first concept through construction. Siemens
experts integrate Siemens expertise with local expertise to get the best from both. At
Lodi Siemens provided field engineers to join the construction management team
working directly for the customer. The Siemens experience and expertise contributed to
improving installation by directly working with the craft sharing Siemens experiences to
avoid installation re-work. Siemens integrated the Power Island and BOP controls
including grid connection, water treatment, etc. into an overall integrated Plant Controls
System.
Siemens also provided in house expertise to assist Customer in interfacing and
obtaining design approval of specialty engineering designs including CBO, Fire Marshal,
and authorized ASME Inspector approvals. This team participated in customer, A/E,
constructor partnering workshops to develop open relationships and communication and
to identify potential project risks and mitigations.

Delivery ahead of time
All OEM equipment for Lodi Energy Center was delivered ahead of schedule.
Siemens assigns a factory load planner to monitor the manufacturing of the gas turbine
and steam turbine for all projects to resolve any schedule issues. For Lodi, a project
expediter was dispatched by the Siemens Orlando-Team to Finspong in Sweden
multiple times during the project to monitor and expedite the critical path steam turbine
manufacturing progress.
Siemens also assigned a project specific site services procurement specialist to support
unplanned or emergency needs for parts or services. For Lodi, they developed a
logistics plan for special rail car usage and transit clearance and routing to ensure the
gas turbine and the generator delivery to site without schedule delays.
