A VESS integrates multiple controllable elements of energy systems, such as traditional energy storage systems, flexible loads, microgrids, distributed generators, multi-vector energy systems and local DC networks. It is able to respond to external signals by varying its. . The use of renewable energy sources is growing rapidly, but this also means that there are more unknown variables and fluctuations in power and voltage. Virtual energy storage systems. . The promising features of VESS are outlined below: • The system can integrate renewable energy sourcesinto distribution networks more easily. Fluctuations in renewable energy generation output can be smoothed by the charging or discharging of a VESS.. [pdf]
American Samoa’s energy sector relies almost entirely on imported fossil fuels, although renewables represent a small but growing power system contribution. The territory possesses substantial solar energy resources, as well as wind and biomass resource potential.
Of the 5 MW of ASPA’s grid-connected solar PV capacity, 4.1 MW is utility scale and 900 kW is distributed across rooftops. American Samoa’s smaller islands are moving toward a combination of solar, batteries, and diesel generators.
Average U.S. and American Samoa Electricity Prices (2022) ASPA rates are down slightly as of January 2024—approximately $0.41/kWh for residential and commercial customers and $0.38/kWh for industrial customers. ASPA’s total energy rates include a renewable energy flat rate charged at $0.002/kWh across all service types (ASPA 2024).
Fuel for American Samoa comes from Singapore with Busan, South Korea as an alternate provider if needed. In the case of fuel disruption, Pacific Energy prioritizes serving ASPA to ensure power and water treatment services are not interrupted (Pacific Energy representative, personal communication, August 9, 2023).
The 2016 American Samoa Energy Action Plan identifies some geothermal resources, but none of these are viable for commercial electricity generation. The 2016 plan instead emphasizes the development of wind and solar power (Ness, Haase, and Conrad 2016). American Samoa is exploring opportunities for both offshore and onshore wind power generation.
American Samoa plans to make these data available to the public, to students of the Finafinau Group (an island community-service project focused on environmental conservation and resilience), and to all other interested parties for science projects and related activities (American Samoa Governor’s Office 2023a).

The Portugal wind energy market is semi-consolidated. Some of the major companies (in no particular order) are Vestas Wind Systems AS, Siemens Gamesa Renewable Energy SA, Oersted AS, Electricite de France SA, and Acciona SA. Need More Details on Market Players and Competitors?
Wind power' is a major source of energy in Portugal. At the end of 2020, wind power capacity in Continental Portugal was 5,456 MW. In 2020, wind power represented 23.7% of total electricity generation. The record of wind power generation was achieved on November 22, 2019 with 103.1 GWh produced
Wind energy is commonly harvested using wind turbines, which consist of large rotating blades mounted on a tall tower. The Portugal Wind Energy market is segmented by location of deployment as Onshore and Offshore. The report offers the market size and forecast on the basis of installed capacity.

Viseu is the distrito with the largest installed capacity, followed by Coimbra, Vila Real and Castelo Branco. The 240 MW Alto Minho Wind Farm in the Viana do Castelo district became fully operational in November, 2008 when Portugal's Economy Minister Manuel Pinho inaugurated it.
For instance, in May 2023, EDP Renewables announced that it had expanded the capacity at its largest wind farm in Portugal. The Alta da Coutada wind farm has a capacity of 187MW, following the installation of six turbines. They are expected to increase the annual production of the wind farm by 12%.
Additionally, Portugal's geographic characteristics, including ample onshore wind resources, make it highly conducive for the development of onshore wind projects. The favorable wind conditions on land, particularly in regions like the Alentejo and Centro, present lucrative opportunities for harnessing wind energy efficiently and sustainably.
