In the coming weeks, the U.S. Supreme Court is expected to rule on a landmark ruling that could have an immediate impact on the energy storage market.
The Supreme Court on Thursday will hear arguments on a case challenging the constitutionality of the federal Energy Storage Tax Credit, which was enacted to help power utilities pay for storage projects.
That ruling could put a huge crimp in the market for energy storage.
A major victory for consumers could make it harder to make big investments in storage.
Energy storage is the technology that powers the electric grid.
It’s used to provide backup power for homes, businesses and schools when power plants are shut down, to store surplus power that isn’t being used or to provide temporary power when a power outage causes major problems for people or businesses.
Energy systems typically use batteries that are charged when power is needed, or use solar panels that charge batteries when it isn’t needed.
There are two types of energy storage: battery-based and renewable.
Both types are considered reliable by regulators and utility executives.
But there’s little evidence that the technology is as reliable as people believe.
In the meantime, the utility companies and the federal government have been arguing over the value of storage.
Storage is expensive, but the costs have fallen over time, and utilities are spending billions to develop and market it.
But in order to get people to pay for energy stored, utilities have had to make huge investments in new storage technology and marketing, said Brian Shipp, a professor at Cornell University’s Energy Policy Institute.
That’s been costly.
For example, the Energy Department has spent $12 billion since 2009 to develop solar-power storage, according to data from the Congressional Research Service.
In that time, the cost of installing storage technology has fallen by 70 percent.
The U.N. Intergovernmental Panel on Climate Change, a group of experts, says the cost per kilowatt-hour of solar power has dropped by 70% since the 1990s.
The price per kWh of solar has dropped even further, from $0.15 to $0 (0.03 cents).
Storage companies say they need to make money, because they are losing money on each kilowatthour they sell.
For solar-energy storage, the most common form is lithium-ion batteries, which are battery-powered, but some are also solar-solar panels that have to charge when power needs are not there.
The battery-generated electricity is stored and then used when power gets back on the grid.
But the price of those batteries has fallen over the years.
They have been cheaper than solar panels, which can store power longer and can use it longer, and the cost has dropped, Shipp said.
The government also has invested billions in renewable energy and storage.
But because of the government subsidies, those costs have also fallen, and now companies are getting paid for the storage technology, said Jeffrey Pugh, director of the Energy Storage Program at the Brookings Institution, a Washington think tank.
The cost of battery storage is lower than solar, but it’s also more expensive, because it requires a large investment in equipment and other infrastructure, Shuck said.
In addition, because of a $15 billion cap on the cost for battery storage in the U .
S., that has been one of the most effective barriers to developing new technologies, Pugh said.
There is a lot of skepticism about energy storage because it’s not fully understood, Shup said.
That skepticism is likely to continue because the technology has never been proven, Shipt said.
