Vehicle-to-grid (V2G) describes a system in which plug-in electric vehicles (PEVs) sell demand response services to the grid. Demand services are either delivering electricity to the grid or reducing the rate of charge from the grid. Demand services reduce the peaks in demand for grid supply, and hence reduce the probability of disruption from load variations. Vehicle-to-load (V2L) and Vehicle-to-vehicle (V2V) are related, but the AC phase is not synchronised with the grid, so the power is only available to "off-grid" load.

The smart grid is an enhancement of the 20th century electrical grid, using two-way communications and distributed so-called intelligent devices. Two-way flows of electricity and information could improve the delivery network. Research is mainly focused on three systems of a smart grid – the infrastructure system, the management system, and the protection system. Electronic power conditioning and control of the production and distribution of electricity are important aspects of the smart grid.
UltraBattery is a trademark of the lead-acid battery technology commercialized by Furukawa Battery Co. Ltd. UltraBattery has thin carbon layers on spongy lead active material for negative plates. The original idea that combines ultracapacitor technology with lead–acid battery technology in a single cell with a common electrolyte came from the Commonwealth Scientific and Industrial Research Organisation (CSIRO).
New Energy for America was a plan led by Barack Obama and Joe Biden beginning in 2008 to invest in renewable energy sources, reduce reliance on foreign oil, address global warming issues, and create jobs for Americans. The main objective of the New Energy for America plan was to implement clean energy sources in the United States to switch from nonrenewable resources to renewable resources. The plan led by the Obama Administration aimed to implement short-term solutions to provide immediate relief from pain at the pump, and mid- to- long-term solutions to provide a New Energy for America plan. The goals of the clean energy plan hoped to: invest in renewable technologies that will boost domestic manufacturing and increase homegrown energy, invest in training for workers of clean technologies, strengthen the middle class, and help the economy.

SMA Solar Technology AG is a German solar energy equipment supplier founded in 1981 and headquartered in Niestetal, Northern Hesse, Germany. SMA is a producer and manufacturer of solar inverters for photovoltaics systems with grid connection, off-grid power supply and backup operations.
Coda Automotive Inc. was a privately held American company headquartered in Los Angeles, California. The company designed and assembled lithium-iron phosphate (LiFePO4) battery systems for automotive and power storage utility applications, and electric cars. Miles Automotive partnered with Hafei and Qingyuan Electric Vehicle to establish Coda Automotive as an affiliate company. The name CODA comes from the musical term for the concluding passage of a piece of music. Coda Automotive has said that it chose the name because its electric vehicle technology represents an end for combustion engine vehicles, and the start of the electric vehicle era.
SolarEdge Technologies, Inc. is a company that developed a DC optimized inverter system.
The energy sector in Hawaii has rapidly adopted solar power due to the high costs of electricity, and good solar resources, and has one of the highest per capita rates of solar power in the United States. Hawaii's imported energy costs, mostly for imported petroleum and coal, are three to four times higher than the mainland, so Hawaii has motivation to become one of the highest users of solar energy. Hawaii was the first state in the United States to reach grid parity for photovoltaics. Its tropical location provides abundant ambient energy.
Fluidic Energy is a corporation based in Scottsdale, Arizona that develops metal–air rechargeable batteries. The company sells systems for energy storage applications from rural electrification to critical backup power and has strong ties throughout the US, Latin America, Asia, and Africa. In March 2015 the Company signed a deal with Caterpillar, which included an equity investment in Fluidic Energy as well as a commercial agreement to collaborate in the microgrid and telecommunications markets. Over the following year, the company announced two separate MOUs for some of the largest renewable-energy rural electrification projects of their kind. The Company is dedicating its operations to “paving the path for the smart, sustainable grid of the future.”
The University of Kansas Sustainable Automotive Energy Infrastructure Initiative, or more commonly referred to as the KU Ecohawks is an ongoing project that works to promote sustainability in the automotive sector. Founded during the beginning of the Automotive industry crisis of 2008–2010 in the U.S., the group recycles old vehicles to run on community wastes and renewables, especially on the University of Kansas campus and not rely on conventional fossil fuel sources that pollute the local and global environment.
China is the world's largest consumer of electricity, and its demand is expected to double by the next decade, and triple by 2035. In 2010, 70 percent of the country's electricity generation came from coal-fired power plants, but the Chinese government is investing heavily in renewable energy technologies. As of 2013, 21 percent of China's electricity generation comes from renewable sources. This represents only 9 percent of overall primary energy consumption in the country. China's latest goal is to increase renewable energy to 9.5 percent of overall primary energy use by 2015. To implement China's new clean energy capacity into the national power grid, and to improve the reliability of the country's existing infrastructure, requires significant upgrades and ultimately, a smart grid.

The Tehachapi Energy Storage Project (TSP) is a 8MW/32MWh lithium-ion battery-based grid energy storage system at the Monolith Substation of Southern California Edison (SCE) in Tehachapi, California, sufficient to power between 1,600 and 2,400 homes for four hours. At the time of commissioning in 2014, it was the largest lithium-ion battery system operating in North America and one of the largest in the world. TSP is considered to be a modern-day energy storage pioneer with significant accomplishments that have proven the viability of utility-scale energy storage using lithium-ion technology. While originally envisioned as a research and development project, TSP operated as a distribution-level resource for SCE and for calendar year 2020, SCE reported that TSP operated in the wholesale energy market with revenue exceeding operating and maintenance costs. In 2021, SCE began the decommissioning of TSP, which was followed by formal decommissioning by state regulators in 2022. The physical dismantlement of TSP is expected to be completed by the end of 2022.
