- Energy Storage Site Selection Study
Our team performed a site selection study to identify energy storage sites that met the requirements of Arizona Public Service’s (APS) 2016 RFP for new generating resources. The results of the study allowed E.On to obtain a site and submit a proposal in response to the RFP on time.
E.On Climate is a large Independent Power Producer who recently decided to enter the energy storage market and is actively developing new energy storage sites throughout the United States. We were retained to select a site to host a new bulk battery energy storage facility. Our professionals researched, aggregated an analyzed data on the following topics from a variety of sources to identify and rank various candidate sites for development of the project:
- Land availability and zoning (due to schedule constraints, finding a favorable site and being successful in securing an option on the land prior to the RFP deadline date was a major risk to the project)
- Transmission access and capacity availability to accept up to 25 MW of additional generating capacity without triggering system impacts that would need to be mitigated by the project
- Transmission deliverability assessment — certain areas in APS’ service territory were favored over others due to the nature of their existing generation fleet as well as their planned generation projects
- APS interconnection queue research and analysis
- Environmental issues (wetlands, floodplain, sensitive species, noise/visual receptors, etc.)
In addition to the site selection study, we provided conceptual site layouts, site descriptions, an interconnection schedule, relative cost differentials, one-line diagrams and site rankings for six candidate sites that were identified by the study.
- Energy storage site selection
- Transmission load flow studies
- Public support analysis
- Must be capable of providing 25 MW of capacity for four consecutive hours
- Must be located in APS service territory and interconnect to APS’ transmission system at 69 kV or higher
- Bulk battery energy storage technology
- Must be able to complete a full duty cycle for each day of the months of June through September
