We operate fourteen hydropower stations, three geothermal power stations and two wind turbines for research purposes in five operating areas in Iceland. In operating power stations, emphasis is placed on a holistic vision, where prudence, reliability and harmony of the operations with environment and society are the guiding principles.
The hydroelectric power stations, historically all run by Landsvirkjun, are central to the existence of Iceland as an industrialized country. The largest power station by far is Kárahnjúkar Hydropower Plant (690 MW), which generates electricity in the area north of Vatnajökull for the production of aluminum.
Nearly all of Iceland's electricity (>99%) is generated from renewables (mainly hydroelectric dams and geothermal). The islands of Grimsey and Flatey rely on diesel as they are not connected to the grid. Over 80% of electricity in Iceland is generated in hydroelectric power stations.

Base Power leases the batteries to homeowners, who pay between $695 and $995 upfront to install 25 kilowatt-hour or 50 kilowatt-hour batteries, both of which dwarf the competition. (For instance, the 25-kilowatt battery doubles a single Tesla Powerwall.) The batteries can keep a household powered for as long as 48 hours, according to the company.
Battery energy storage is rapidly transforming the U.S. power landscape. In 2025, utility-scale battery storage is projected to expand by a record 18.2 GW, following a historic 10.3 GW added in 2024. These systems play a crucial role in balancing supply and demand, enhancing grid stability, and supporting the integration of renewable energy.
In exchange for the low upfront cost, Base Power customers agree to allow the company to use the batteries to sell electricity back to the grid when they don't need them for backup power. In addition to expansion beyond Texas, the company is also planning to build a second battery factory in the United States.
The Morro Bay Battery Energy Storage System (BESS) is a proposed 600 MW / 2,400 MWh facility on 43 acres of the former Morro Bay Power Plant site in California. Developed by Texas-based Vistra Energy, the project aims to repurpose an inactive coastal power station into one of the largest standalone battery storage projects in the state.
A public benefit corporation, NYSERDA has been advancing energy solutions and working to protect the environment since 1975. The Battery Energy Storage System Guidebook contains information, tools, and step-by-step instructions to support local governments managing battery energy storage system development in their communities.
Most residential battery installations complete in a single day, though complex retrofits might require two days. Equipment mounting begins the physical installation. Wall-mounted batteries require substantial brackets capable of supporting 250+ pounds safely.
If your existing solar system works well, AC-coupled battery addition offers the simplest upgrade path. This approach installs a separate battery inverter alongside your existing solar inverter, allowing both systems to operate independently. Cost considerations favor AC-coupled retrofits for most homeowners.
Solar battery installation costs vary dramatically based on system complexity, local labor rates, and equipment choices. Understanding these factors helps you budget accurately and identify fair pricing. Labor costs typically range from $1,500-4,000 depending on installation complexity.
