Currently focusing on projects in the Northeast United States in the PJM and NYISO market areas, IMG Midstream develops, constructs, and operates environmentally friendly, distributed power generation projects. Using locally produced natural gas that would otherwise be exported from the region, IMG creates electricity that is placed into the regional grid and used locally.
All plant sites are wholly owned subsidiaries of IMG Midstream and are built using similar size, capacity and equipment to allow for economics of scale and operating efficiencies in building, operating and maintenance costs. All IMG sites are located in close proximity to natural gas production as well as local substations to maximize utilization of existing infrastructure and minimize the need for additional infrastructure to be built.
IMG’s utilizes a mix of efficient technologies along with a one-of-a-kind energy supply chain deployment design. IMG breaks from current generation practices by creating a multi-faceted distributed generation asset that is:
- Thermally efficient (Engine alone- 47%-48.5%);
- On demand and flexible with the ability to reach full output in <5 minutes;
- Complementary and enabling to renewable assets and micro grid infrastructure; and
- Low impact to the local community, due to its small plant footprint (2 acres).
The dispersed nature of IMG’s clusters effectively shortens two energy supply chains: gas and electric. By locating its projects close to gas production wells and pipelines, IMG purchases gas further up the supply chain, leading to a higher life cycle efficiencies. The smaller output and footprint of the plants allows them to be located on sub transmission and distribution electric lines, closer to end users, leading to lower transmission losses and improved grid stability.
Shortened Supply Chain Environmental Benefits:
Distribution Grid- IMG has designed and sized its plants to be able to generate needed electricity on local distribution lines (25kV- 34kV). By locating on the distribution grid, IMG significantly reduces the electricity supply chain layers and lowers line losses by up to 5%. This reduction in losses leads to higher efficiency and reduced effective GHGs per MWH delivered.
Gas Production-IMGs plants are strategically sited near gas production. This shortening of the gas supply chain helps avoid gas transportation, procession, compression, and storage. These gas delivery components add up to a 13% loss in gas throughout the supply chain. The gas is lost due to combustion and fugitive methane emissions. By drastically shortening this supply chain IMG reduces CO2 and methane emissions along with improving the lifecycle efficiency of the supply chain.
Advanced plant technology benefits:
Ultra efficient engines- IMG worked with GE and Rolls-Royce identify the best RICE engines for distributed generation in the US energy market. These engine’s efficiency (47-48.5%) bring a lower carbon resource to distributed generation.
Emissions Controls- IMG’s engines utilize compact SCR/oxidation catalyst emissions controls to reduce the NOX, CO, VOC, and HCOH emissions of its plants by up to 96% lower than Federal New Source Performance Standards Subpart JJJJ for minor sources.
