Onsite Power Generation

GreenGen can assess, engineer, and implement onsite power generation, helping you wade through the many choices to identify ROI-based alternatives.

GreenGen's Engineering Team evaluates the potential for innovative energy technologies utilizing renewable power sources such as solar, wind, and geothermal, as well as onsite generation (CHP). GreenGen enables clients to benefit from efficient and reliable power sources that shield them from volatile energy markets while reducing their carbon emissions.

GreenGen develops the most efficient renewable energy projects possible – from site selection to asset management, we provide a broad range of services along the entire value chain.

Microgrids

GreenGen specializes in designing and optimizing both utility grid-connected and standalone microgrids. A microgrid consists of both electricity sources and loads, as well as energy storage systems in some cases. Electricity sources can be either fossil fuel-based electricity generators such as gas turbines, micro turbines, and reciprocating gas generators; or they may be renewable sources like solar, wind, or hydroelectric. In a grid-connected design, both energy generation sources and consumers are connected to a utility grid helping to reduce the necessary systems regarding handling the microgrid active and reactive loads, and the microgrid complexity. Connection to the grid may provide an opportunity to generate revenue by exporting energy during the high demand periods and helping utility companies with load balance by importing more electricity from the grid to either consume or store the grid’s excess electricity. Standalone microgrids require additional systems to balance electricity loads and are more complex than grid-connected systems. They may also require energy storage systems, particularly in the case of standalone grids that rely on renewable energy sources for the majority of their demand.

CHP / Co-Generation

Our CHP designs make use of natural gas effectively to create electricity and thermal energy in a cost-effective manner. CHP systems utilize the power generation waste heat to satisfy the building's heat demands.

CHP systems typically consist of commercially available gas-fired reciprocating engines or turbine-based technologies primarily producing electricity with waste heat creating thermal energy on a secondary basis. A third benefit is reduced electrical peak demand during the summer. With a minimum 60% annual efficiency and reduced GHG emissions, CHP is often an excellent option for facilities to reduce both operating costs and GHG. With black start capability, CHP systems also provide excellent energy security and grid redundancy.

Additionally, GreenGen helps secure the strong federal and local incentives for CHP that are offered in many markets.

Renewables

Renewable energy commercialization involves the deployment of three generations of renewable energy technologies dating back more than 100 years. First-generation technologies, which are already mature and economically competitive, include biomass, hydroelectricity, geothermal power and heat. Second-generation technologies are market-ready and are being deployed at the present time; they include solar heating, photovoltaics, wind power, solar thermal power stations, and modern forms of bioenergy. Third-generation technologies are currently in development.

Energy Storage Systems

GreenGen offers both electricity energy storage systems and thermal storage systems. For electricity storage system, GreenGen designs and optimizes battery storage systems for data centers, microgrids, grid balancing and also emergency backup electricity systems. For thermal storage systems the solution includes phase change materials (PCM technology) and non-phase change materials. Energy storage systems can reduce the energy expenditure, especially for sites with time-of-use electricity rates or high demand costs, as well as sites that have large renewable electricity sources.

Smart Grid

A smart grid is a microgrid in which major components  including electricity sources, major loads, electricity meters, and energy storage systems  communicate with each other in real-time and can be operated and optimized as an integrated system. With advanced control systems imbedded in the smart grids, it is possible to reduce energy consumption while improving microgrid stability. With expertise in building systems, power generation, and storage systems, GreenGen can help its clients design new smart grid systems or optimize and modernize existing microgrids in order to reduce energy and operational costs.
