RENEWABLES

SOLAR AND BATTERY ENERGY STORAGE SYSTEMS

Patch Services is participating in the development of a number of Solar Photovoltaic and Battery Energy Storage System Projects in the United States. The PV Projects range in size from 20MW to 150MW while the BESS Projects range in size from 32MW 4-hr systems to ggMW 1-hr systems. Providing engineering, Owner's Engineer services, consulting and technical support to these Projects, Patch Services' responsibilities range from conceptual engineering, preliminary engineering, Project consulting, preparing CAPEX estimates and EPC contract specifications as well as Construction Management and support to the environmental permitting activities required for the Projects.

 

The typical engineer, consulting and technical support provided in the Development, Licensing and Execution phase of the Project includes both conceptual engineering design as well as preliminary engineering design. Responsibilities for the development and preparation of the Project Description, which forms the Design Basis for the project, the engineering control documents are developed and establish the basis for Project Development and Permitting/Licensing Applications.

 

(BESS at High Dessert)

This 50MW, 200MWh BESS is a recent major addition to California's renewable energy portfolio. Co-located with a 100MW PV installation, this project was brought on line in 3Q2021. Both AC and DC coupled, the BESS provides incremental power to CAISO/SCE's transmission system and will utilize the available ITC. Throughout execution of this Project, Owner's Engineering support was provided from permitting to contracting to EPC to Project Commissioning and performance testing. 

Currently, Patch Services is working with Clients supporting the development of one gigawatt of BESS Projects in California. These multiple Projects provide the ability to meet both demands as well as support ancillary services.

BIOMASS ENERGY

Patch Services is committed to the renewable sector of energy generation. Biomass involvement is one of the many approaches in which we demonstrate our commitment to developing innovative and economically successful projects for the generation of clean renewable energy.

Patch Services is participating in various Biomass projects throughout the United States. We are completing all of the engineering services required to design and construct each facility. For these projects, Patch Services is providing:

  • Overall design and Construction Details

  • Development of the heat and mass balances

  • Process Flow Diagrams and Equipment Data Sheets

  • Selection of the Steam Turbines, Fuel Silos, Fuel Handling Conveyors, Boilers, Condensers as well as other major mechanical equipment

  • Specified components of the engineered equipment and provided process control integration

  • Developed Logic and Schedule for Project Management and Completion

  • Preparation of Electrical Interconnection Applications

  • Preparation of the Electrical Single-Line

  • Preparation of discipline Specifications required

RESEARCH & DEVELOPMENT 

Patch Services has multi-partnering relationships with several entities providing true R&D efforts for the generation of clean energy. Patch has worked with a number of partners in achieving the process of developing a truly unique and innovative technology for the production of steam to drive a steam turbine and capture commercial-grade CO2. Patch Services has presented technical papers at the world's largest Power Generation Event. 

Patch services responsibilities in these revolutionary projects include:

  • Development of the PFD's

  • Development of the P&ID's 

  • Equipment selection necessary to support CES's proprietary Gas Generator

  • Detailed engineering required to construct 500KW Pilot Plant
