Integrating Systems
Within Water and
Energy Networks
commercial buildings, with benefits for both customers and energy suppliers
✔ carbon reductions achieved through the electrification
of water systems, replacing fossil fuel point sources and
increasing efficiency for the pumping, heating, treatment, and transport of water and wastewater
✔ off-peak water treatment, water heating, and water
pumping to reduce both energy costs and generating-unit downturn
✔ distributed water treatment/WWT and local reuse,
providing greater system security and resiliency
✔ expanded availability of Energy Star and WaterSense appliances for water and energy savings, enabling easy ways to achieve customer savings and
satisfaction as well as to implement energy and water conservation methods.
In particular, water presents strategic challenges and
opportunities for the electric sector.
✔ Using less water for power production conserves a
scarce resource for other necessary uses.
✔ Minimizing the environmental impacts of water use
for power production preserves environmental resources and protects human health.
✔ Using efficient electric technologies for water treatment, transport, desalination, industrial processes,
and other end uses can conserve electricity, thereby
reducing any imbedded water demand.
energy end user, called a prosumer, who may also produce
energy. Similarly, the water network has taken on an increasingly dynamic role as more decentralized, small-scale
systems are implemented. Think of the interaction between
the water network and the smart electric grid as the integrated energy network (or "integrated network of resources"),
where further efficiencies may be gained through this integration of systems. With this integration, we drive resource
use toward a more sustainable and efficient utilization and
management of resources (Figure 2)
Many potential benefits can be realized by integrating
the electricity and water sectors. Some examples include
✔ load leveling, e.g., pricing signals used to control
demand for systems such as water pumping to head
tanks, desalination, wastewater treatment (WWT), irrigation pumps, and water heaters in residential and
