This document discusses distributed energy systems (DES) which encompass energy generation, storage, monitoring and control solutions located near where energy is used. It provides examples of common distributed generation technologies for residential, commercial and industrial sectors like solar panels, wind turbines, fuel cells and backup generators. The document discusses how distributed energy resources (DER) can provide economic, social and environmental benefits by reducing costs, emissions and enabling affordable energy access. While DER has positive impacts through renewable energy use and reduced transmission losses, it also has potential negative impacts like pollution from fossil fuel combustion, land use concerns and water usage.

2. Distributed energy system (DES) is a term which encompasses a
diverse array of energy generation, storage, monitoring and
control solutions.

3. INTRODUCTION :
• Distributed generation refers to a variety of technologies that
generate electricity at or near where it will be used, such as
solar panels and combined heat and power.
• Distributed generation may serve a single structure, such as a
home or business, or it may be part of a microgrid (a smaller
grid that is also tied into the larger electricity delivery
system), such as at a major industrial facility, a military base,
or a large college campus.
• When connected to the
electric utility’s lower
voltage distribution lines,
distributed generation can
help support delivery of
clean, reliable power to
additional customers and
reduce electricity losses
along transmission and
distribution lines.

4. 1. In the residential sector, common distributed generation
systems include:
solar photovoltaic panels
small wind turbines
natural-gas-fired fuel cells
emergency backup generators, usually fueled by gasoline or diesel
fuel.
2. In the commercial and industrial sectors, distributed generation
can include resources such as:
combined heat and power systems
solar photovoltaic panels
wind
hydropower
biomass combustion or cofiring
municipal solid waste incineration
fuel cells fired by natural gas or biomass
reciprocating combustion engines, including backup generators,
which are may be fueled by oil.
DISTRIBUTED ENERGY RESOURCES (DER) :

5. • Within the last century, massive population and economic
growth have accelerated the global consumption of energy to
unprecedented levels, with nearly 30% of the world’s total
energy being consumed by buildings.
• According to the Electricity Network Transformation Roadmap
(ENTR), more than 40% of energy customers will use DER by
2027 and by 2050, that figure will grow to more than 60%.
• The report found that distributed energy systems can provide
significant economic, social and environmental benefits
including lower cost grid balancing, reduced greenhouse gas
emissions and affordable extension of grids to unconnected
communities.
• As more building owners think about their long-term energy
goals and future-proofing their buildings, DES can provide a
means of reducing operational costs and ensuring long-term
energy security.

7. ENVIRONMENTAL IMPACTS OF
DISTRIBUTED GENERATION :

8. POSITIVE ENVIRONMENTAL IMPACT :
• Existing cost-effective distributed generation technologies can
be used to generate electricity at homes and businesses using
renewable energy resources such as solar and wind.
• Distributed generation can harness energy that might otherwise
be wasted—for example, through a combined heat and power
system.
•By using local energy
sources, distributed
generation reduces or
eliminates the “line loss”
(wasted energy) that
happens during
transmission and
distribution in the
electricity delivery system.

9. • Distributed generation systems require a “footprint” (they take
up space), and because they are located closer to the end-user,
some distributed generation systems might be unpleasant to the
eye or cause land-use concerns.
• Distributed generation technologies that involve combustion—
particularly burning fossil fuels—can produce many of the same
types of impacts as larger fossil-fuel-fired power plants, such as
air pollution. These impacts may be smaller in scale than the
impacts from a large power plant, but may also be closer to
populated areas.
• Some distributed generation technologies, such as waste
incineration, biomass combustion, and combined heat and
power, may require water for steam generation or cooling.
• Distributed generation systems that use combustion may be less
efficient than centralized power plants due to efficiencies of
scale.
