Energy Storage has become a focal point within the industry as its potential for transforming the grid and reducing carbon emissions becomes more economically feasible. As a full-service energy market expert, IEC provides all phases of energy storage services, from initial market assessment through turnkey engineering, procurement, and construction (EPC) services, for utility-scale and commercial energy storage projects.
Design & Installation
Design & Installation As a turnkey energy storage contractor, IEC designs and installs energy storage projects for multiple technologies, including battery energy storage systems for utilities, commercial clients, and school districts. Our contracting team conducts permitting, design, and engineering and executes project implementation, including construction, installation, and commissioning to achieve commercial operation. Services include • Permitting • Design • Installation • CommissioningBattery Storage Project ExperienceCenter Peaker Battery Energy Storage (BES) Project (10MW)Owner: Southern California EdisonIEC was contracted to provide complete design services for a Battery Energy Storage project owned by Southern California Edison (SCE). For the Center Peaker Battery Energy Storage Project, IEC was the Engineer of Record (EOR) and provided detailed engineering services for civil/structural, electrical, and mechanical. IEC’s scope of work included developing and designing complete permit and construction packages which required us to develop a project design criteria and work closely with the owner, equipment suppliers, and construction contractor to ensure all project requirements were met. The project was approved by both SCE and the local building department and became operational early 2017. The battery project includes a 10MW/4.3MWh (AC) General Electric Co. (“GE”) Battery Energy Storage System that will be fully integrated with an existing power plant. Grapeland Peaker Battery Energy Storage (BES) Project (10MW)Owner: Southern California EdisonIEC was contracted to provide complete design services for a second Battery Energy Storage project owned by Southern California Edison (SCE). For the Grapeland Peaker Battery Energy Storage Project, IEC was the Engineer of Record (EOR) and provided detailed engineering services for civil/structural, electrical, and mechanical. IEC’s scope of work included developing and designing complete permit and construction packages which required us to develop a project design criteria and work closely with the owner, equipment suppliers, and construction contractor to ensure all project requirements were met. The project was approved by both SCE and the local building department and became operational early 2017. The battery technology utilizes lithium ion battery modules in a prefabricated enclosure, connected to industrial grade power inverters, and is connected to the existing peaker plant 13.8 kV electrical system. This project is also a 10MW/4.3MWh (AC) General Electric Co. (“GE”) Battery Energy Storage System that will be fully integrated with an existing power plant. OCI Solar Battery Energy Storage (BES) SystemClient: OCI Solar Power LLC The OCI Solar Battery Energy Storage Project is a new 1 MW battery storage system and PV System at the Alamo 1 Substation. The new battery storage ties into the existing substation and provides an additional source to the grid. IEC provided engineering design services for modifying the existing substation protection scheme to incorporate the new energy storage system. Services included designing a new control scheme between the solar plant, battery energy storage project, existing substation and utility interconnection. The new substation protection design ensures automatic electrical coordination for both solar and energy storage systems.
Feasibility Studies& Due Diligence Our experts also evaluate and model the potential capital costs and technical variables involved for each energy storage project—such as peak output, energy storage duration, response time, technology, durability, market scenarios, and business models—to weigh against expected benefits. This is a crucial component of the energy planning process. Services include • Resource and Siting Studies • Technology Review • Fatal Flaw Analysis • Equipment Evaluations • Contract(s) Review • Cost and Risk Analysis • Financing and Ownership Options • Regulatory and Permit Compliance • Energy Yield Predictions • Project ValuationFinancial Analysis IEC evaluates and balances each energy storage solution to consider capital costs, operating costs and revenue streams such as energy arbitrage, flexible capacity value, system balancing and congestion management. Due to each project’s unique criteria, IEC works with our clients to develop customized financial models to evaluate and rank each potential project based on potential value streams and the client’s energy goals. Services include • Initial Screening and Qualification • Due Diligence • Financial and Risk Analysis • Financial Modeling • Project Economics Evaluations • Sensitivity Analysis • Tax Effects and Depreciation • Financial Incentives Analysis • Utility Tariffs • Project Variance, Cost, and other Financial Analysis
Battery StoragePumped Storage HydroThermal Energy StorageOur project team evaluates battery storage options to develop and execute customized solutions that meet the specific needs and demands of our utility and commercial clients based on resources, location/footprint, regulations, existing systems, environment, and schedules. As an EPC contractor, we are not attached to one type of technology, and are instead focused on finding the right state-of-the art battery technology for each project, including lithium-ion technologies, lead-acid products, and flow cell batteries. We maintain relationships with a wide variety of product developers and suppliers to facilitate a timely procurement process and ensure quality equipment. In addition, our engineers are experienced in developing projects that integrate battery storage systems with existing power generation facilities.Battery StoragePumped storage is a proven grid-scale energy storage technology with the capacity to store large quantities of electricity. These facilities supply a sustainable, reliable, and emission-free energy source that provides frequency control and reserve generation. The technology is also dispatchable to help accommodate increasing amounts of intermittent energy. IEC's staff has worked on large hydroelectric facilities throughout the western United States ranging in size from less than 6 MW to more than 400 MW. These projects have included turbines and pump-turbines configured in and aboveground and belowground powerhouses. Our team is able to develop functional designs for fully integrated hydroelectric pumped-storage powerhouses while facilitating regulatory acceptance and ensuring optimal integration with the overall utility systems and power grid. We maintain a particular focus on properly addressing environmental and community impacts and ensuring safety during construction and operations.Pumped Storage HydroThermal Energy Storage (TES) Systems allow excess thermal energy to be collected for later use while expanding the capacity of existing chilled water systems. These systems save utility costs, reduce the need for new generating facilities and/or grid upgrades, and assist in peak shaving efforts. Our team has supported a wide range of thermal energy and energy storage options for facilities ranging from hospitals, hotels, and prisons to utility-scale power facilities and industrial facilities. IEC works with our utility and commercial/industrial clients to model and analyze the optimum TES equipment and configuration, as well as providing detailed engineering design, procurement and construction of the system.Thermal Energy StorageTechnology Selection IEC advises our utility, commercial, and industrial clients on the best fit storage technology for their application. Our consulting capabilities include technical knowledge for both large grid-scale energy storage applications as well as smaller commercial-scale solutions. Technologies include battery storage, pumped hydro, thermal energy storage (TES), compressed air energy storage (CAES), and hydrogen.
