The U.S. Environmental Protection Agency’s (EPA’s) plan to regulate carbon emissions is just the latest challenge facing the U.S. electric power system. Technological innovation is disrupting old ways of doing business and accelerating grid modernization. Earlier this year, AEE released Advanced Energy Technologies for Greenhouse Gas Reduction, a report detailing the use, application, and benefits of 40 specific advanced energy technologies and services. This post is one in a series drawn from the technology profiles within that report.

 

Energy_AnalyticsEnergy analytics for mass-scale building energy efficiency evaluations is a category of software solutions that determine how a building is currently consuming energy and recommend operational and retrofit measures to maximize energy savings. Energy analytics combine different types of data inputs, such as consumption or building asset data, with advanced analytics and modeling techniques to rapidly generate a unique building energy model. Leveraging big data energy analytics via the cloud saves substantial time and costs compared with the traditional manual methods of performing building assessments and audits.

District_EnergyJust as electricity is distributed over networks of wires to many buildings, it is also possible to distribute heating and cooling via networks of pipes. District energy systems produce steam, hot water, and/or chilled water at central plants and, through a network of insulated pipes (often underground), distribute the steam or water to multiple buildings. District energy plants often include power generation, typically CHP, which further increases overall efficiency.

Demand_ResponseDemand Response (DR) is a mechanism that allows utilities to provide customers with information and incentives that encourage customers to reduce energy usage at specific times of the day or year. This gives customers more control over their energy usage and costs, while providing valuable services to grid operators, namely load reduction during peak hours, when electricity is expensive or when grid reliability is compromised. Demand response customers may implement control technology that automatically responds to price or other signals, or customers may respond to a demand response request manually.

Industrial_CHPIndustrial Combined Heat and Power (CHP, also called cogeneration) uses a single fuel, often natural gas, to co-produce electricity and heat for use in industrial operations, usually on site. Industrial CHP accounts for more than 75 GW out of the approximately 82 GW of installed CHP in the United States, or 7% of the country’s total generation capacity. CHP can be applied widely within the industrial sector, but is particularly well suited for industries with significant, steady thermal loads such as refining, chemicals, pharmaceuticals, and forest products.

Advanced Energy Technology of the Week: Combined Heat and Power (CHP)

CHPCombined Heat and Power (CHP), also called cogeneration, generates both electricity and useful heat from the same fuel source. CHP typically involves dedicated equipment to generate electricity, followed by recovery of exhaust/waste heat for use in industrial processes, space heating, or water heating. Any fuel can be used for CHP, including fossil fuels and renewable fuels. In certain industries, onsite “waste” fuels are used for CHP, such as wood chips, bark and sawdust in forest products, blast furnace gases in steel mills, and various process gas streams in refining and petrochemicals. Because thermal energy (steam, hot water) is more difficult to transport than electricity, CHP systems are typically installed at or near a suitable thermal load. Most U.S. CHP capacity is installed at industrial sites, but it is also fairly common at college campuses, hospitals, military bases, and in district energy plants.[1] Housing complexes and commercial buildings also use CHP. So-called micro-CHP can be used in residences and small commercial buildings for water or space heating or for heating swimming pools. CCHP (combined cooling, heating, and power) is a variation of CHP that uses the waste heat to drive a cooling system (via an absorption chiller) in addition to generating heat and power. CCHP can make sense when heating loads are more seasonal and where there are large cooling requirements, resulting in higher overall utilization of waste heat than would be possible just with CHP.
