Complementary Measures Land use planning that encourages compact, complete communities. A Community Energy Plan to develop strategies for energy infrastructure within a broader energy and emissions plan. The CEA created a Community Energy and Emissions Planning guide which describes the purpose and content of a community energy and emissions plan, its benefits, and how to go about creating one. Resource Management Plans and Integrated Resource Recoveryencourage energy inputs from several sources such as refrigeration-heat from an ice-rink, sewer heat, biomass, etc providing more opportunities for carbon-neutral energy.
Cogeneration[ edit ] Distributed cogeneration sources use steam turbines, natural gas-fired fuel cellsmicroturbines or reciprocating engines  to turn generators. The hot exhaust is then used for space or water heating, or to drive an absorptive chiller   for cooling such as air-conditioning.
In addition to natural gas-based schemes, distributed energy projects can also include other renewable or low carbon fuels including biofuels, biogaslandfill gassewage gascoal bed methanesyngas and associated petroleum gas.
With a Lifetime of around 60, hours. For PEM fuel cell units, which shut down at night, this equates to an estimated lifetime of between ten and fifteen years.
Photovoltaic system Photovoltaicsby far the most important solar technology for distributed generation of solar poweruses solar cells assembled into solar panels to convert sunlight into electricity. It is a fast-growing technology doubling its worldwide installed capacity every couple of years.
PV systems range from distributed, residential, and commercial rooftop or building integrated installations, to large, centralized utility-scale photovoltaic power stations. The predominant PV technology is crystalline siliconwhile thin-film solar cell technology accounts for about 10 percent of global photovoltaic deployment.
It produces peak power around local noon each day and its capacity factor is around 20 percent. Wind power Wind turbines can be distributed energy resources or they can be built at utility scale.
These have low maintenance and low pollution, but distributed wind unlike utility-scale wind has much higher costs than other sources of energy. Wind towers and district energy systems business plan have substantial insurable liabilities caused by high winds, but good operating safety.
Distributed generation from wind hybrid power systems combines wind power with other DER systems. One such example is the integration of wind turbines into solar hybrid power systemsas wind tends to complement solar because the peak operating times for each system occur at different times of the day and year.
Small hydro and Wave power Hydroelectricity is the most widely used form of renewable energy and its potential has already been explored to a large extent or is compromised due to issues such as environmental impacts on fisheries, and increased demand for recreational access.
However, using modern 21st century technology, such as wave powercan make large amounts of new hydropower capacity available, with minor environmental impact. Modular and scalable Next generation kinetic energy turbines can be deployed in arrays to serve the needs on a residential, commercial, industrial, municipal or even regional scale.
Microhydro kinetic generators neither require dams nor impoundments, as they utilize the kinetic energy of water motion, either waves or flow. No construction is needed on the shoreline or sea bed, which minimizes environmental impacts to habitats and simplifies the permitting process.
Such power generation also has minimal environmental impact and non-traditional microhydro applications can be tethered to existing construction such as docks, piers, bridge abutments, or similar structures.
Waste-to-energy and Waste-to-energy plant Municipal solid waste MSW and natural waste, such as sewage sludge, food waste and animal manure will decompose and discharge methane-containing gas that can be collected and used as fuel in gas turbines or micro turbines to produce electricity as a distributed energy resource.
This power can be used in lieu of grid-power at the waste source such as a treatment plant, farm or dairy. Grid energy storage A distributed energy resource is not limited to the generation of electricity but may also include a device to store distributed energy DE.
PV storage[ edit ] Common rechargeable battery technologies used in today's PV systems include, the valve regulated lead-acid battery lead—acid batterynickel—cadmium and lithium-ion batteries. Compared to the other types, lead-acid batteries have a shorter lifetime and lower energy density.
Furthermore, as storage devices for PV systems are stationary, the lower energy and power density and therefore higher weight of lead-acid batteries are not as critical as for electric vehicles.
In addition, the Li-ion batteries of plug-in electric cars may serve as future storage devices, since most vehicles are parked an average of 95 percent of the time, their batteries could be used to let electricity flow from the car to the power lines and back.
Other rechargeable batteries that are considered for distributed PV systems include, sodium—sulfur and vanadium redox batteries, two prominent types of a molten salt and a flow battery, respectively.
Flywheels can respond quickly as they store and feed back electricity into the grid in a matter of seconds. Various technical and economic issues occur in the integration of these resources into a grid.
Technical problems arise in the areas of power qualityvoltage stability, harmonics, reliability, protection, and control.
Each distributed generation resource has its own integration issues.Share expertise with district energy leaders in operation, design, construction, and optimization of district heating, district cooling, and combined heat and power (CHP) systems located in cities, communities and on campuses and owned and operated by public and private utilities, municipalities, hospitals, military bases and airports.
District Energy Systems are networks of hot and cold water pipes, typically buried underground, that are used to efficiently heat and cool buildings using less energy than if the individual buildings were to each have their own boilers and chillers.
