Just as PV systems can be installed in small-to-medium-sized installations to serve residential and commercial buildings, so too can energy storage systems—often in the form of lithium-ion batteries. NREL researchers study the benefits of such systems to property owners, their impact on the electric grid, and the effects on. .

The Storage Futures Studyconsidered when and where a range of storage technologies are cost-competitive, depending on how they're operated and what services they provide. [pdf]
For solar-plus-storage—the pairing of solar photovoltaic (PV) and energy storage technologies—NREL researchers study and quantify the unique economic and grid benefits reaped by distributed and utility-scale systems. Much of NREL's current energy storage research is informing solar-plus-storage analysis.
This suggests that business models built around these lower-valued PV system attributes may not be viable, unless they can also take advantage of the other more lucrative value streams. In this business model, the customer or a third party controls the PV system as well as owns it.
Current PV business models principally revolve around the ownership of PV systems by individuals and increasingly by third parties, rather than by utilities. At today’s low levels of market penetration, distributed, grid-connected PV is not a central concern nor even of great interest to most utilities.
Energy storage has become an increasingly common component of utility-scale solar energy systems in the United States. Much of NREL's analysis for this market segment focuses on the grid impacts of solar-plus-storage systems, though costs and benefits are also frequently considered.
It appears to be a question of when, and not if, there will be a need for new PV business models, in order to accommodate and facilitate widespread adoption of distributed PV. Current PV business models principally revolve around the ownership of PV systems by individuals and increasingly by third parties, rather than by utilities.
Huijben and Verbong identified that business models providing different ownership structures facilitated the development and growth of distributed solar PV. Amus suggested that adopting a community business model addressed infrastructural hindrances, making it cost-efficient for consumers to utilise solar PV.

Svalbard and Jan Mayen (Norwegian: Svalbard og Jan Mayen, ISO 3166-1 alpha-2: SJ, ISO 3166-1 alpha-3: SJM, ISO 3166-1 numeric: 744) is a statistical designation defined by ISO 3166-1 for a collective grouping of two remote jurisdictions of Norway: Svalbard and Jan Mayen.
Svalbard and Jan Mayen have in common that they are the only integrated parts of Norway not allocated to counties. While a separate ISO code for Svalbard was proposed by the United Nations, it was the Norwegian authorities who took initiative to include Jan Mayen in the code. Its official language is Norwegian.
The United Nations Statistics Division also uses this code, but has named it the Svalbard and Jan Mayen Islands. Svalbard is an archipelago in the Arctic Ocean under the sovereignty of Norway, but is subject to the special status granted by the Svalbard Treaty.
ISO 3166-2:SJ is the entry for Svalbard and Jan Mayen in ISO 3166-2, a system for assigning codes to subnational administrative divisions. However, further subdivision for Svalbard and Jan Mayen occurs under Norway's entry, ISO 3166-2:NO:

科科斯(基林)群岛(英語:Cocos (Keeling) Islands)是位於的 ,位於澳大利亞本土與之間的南緯12°0′00″ 東經96°30′00″。群島面积達14.2;人口有628人(至2005年7月),由27座島組成。仅家岛(Home Island)和(West Island)有人居住。科科斯(基林)群岛的位于西岛。 . The Cocos (Keeling) Islands consist of two flat, low-lying coral atolls with an area of 14.2 square kilometres (5.5 sq mi), 26 kilometres (16 mi) of coastline, a highest elevation of 5 metres (16 ft) and thickly covered with coconut palms and other vegetation. The climate is pleasant, moderated by the southeast for about nine months of the year and with moderate rainfall. [pdf]
The Cocos (Keeling) Islands have access to a range of modern communication services. Digital television stations are broadcast from Western Australia via satellite. A local radio station, 6CKI – Voice of the Cocos (Keeling) Islands, is staffed by community volunteers and provides some local content.
Sign boards on the island also feature Malay translations. The Cocos (Keeling) Islands consist of two flat, low-lying coral atolls with an area of 14.2 square kilometres (5.5 sq mi), 26 kilometres (16 mi) of coastline, a highest elevation of 5 metres (16 ft) and thickly covered with coconut palms and other vegetation.
John Clunies-Ross, who sailed there in the Borneo in 1825, called the group the Borneo Coral Isles, restricting Keeling to North Keeling, and calling South Keeling "the Cocos properly so called". The form Cocos (Keeling) Islands, attested from 1916, was made official by the Cocos Islands Act 1955 (3 & 4 Eliz. 2.
The territory's dual name (official since the islands' incorporation into Australia in 1955) reflects that the islands have historically been known as either the Cocos Islands or the Keeling Islands. The territory consists of two atolls made up of 27 coral islands, of which only two – West Island and Home Island – are inhabited.
It is available in paper and electronic formats. The Cocos (Keeling) Islands receives a range of digital channels from Western Australia via satellite and is broadcast from the Airport Building on the West Island on the following VHF frequencies: ABC6, SBS7, WAW8, WOW10 and WDW11
