California’s new net-metering policy brings batteries to forefront – pv magazine International


Whereas NEM 3.0 is anticipated to inflate the charges paid for photo voltaic offered again to the grid, the batteries will assist keep the worth of PV. Nonetheless, the subsequent wave of unpolluted expertise adoption ought to give attention to non-lithium batteries and exploit protected, low cost chemical substances.

From pv journal USA

California’s net-energy metering (NEM) coverage is a key driver of photo voltaic deployment within the state, encouraging adoption by permitting utility clients to promote extra energy generated from rooftop photo voltaic again to the grid. for revenue. With roughly 1.5 million properties and companies taking part, insurance policies like these make California a clear power chief in the US, and even the world. Nonetheless, the California Public Utilities Fee not too long ago modified its solar-friendly coverage.

The accredited new framework (often called NEM 3.0) is anticipated to extend the speed paid for photo voltaic power offered again to the grid by 75%. This revision considerably extends the five- to seven-year common payback interval for photo voltaic installations and places the expansion of solar energy in danger. Californians should embrace a further clear power expertise to shorten payback durations and hold the power behind photo voltaic: batteries.

Below the brand new NEM 3.0 charge construction, the quantity of extra photo voltaic generated throughout the day is decreased. Nonetheless, there’s a strategically designed loophole – owners and companies can retain the quantity of solar energy generated by incorporating a battery into their system. The battery can retailer extra power for later use, together with instances of the day when power demand and costs are at their highest.

This new construction will profit California’s electrical energy grid by decreasing reliance on fossil fuels throughout peak demand. As a state that usually experiences electrical energy provide shortages and rolling blackouts, California has the chance to mitigate these points by utilizing batteries and renewables as distributed power sources. As well as, battery methods will allow California companies to speed up their paths towards decarbonization, which is remitted by regulation within the coming years.

As demand for solar-plus-storage grows, lithium-ion battery producers are racing to maintain up. Nonetheless, regardless of the pressing want for storage as electrical energy costs rise and grid reliability nosedive, many residence and enterprise house owners stay hesitant. Lithium-ion batteries have their very own dangers, together with elevated prices and fireplace hazards.

In 2022, the typical lithium-ion battery pack value reversed the downward development and rose 7% to $151/kWh. In 2021, the preliminary price (together with the price of all {hardware} and the price of your complete set up) for a ten kWh to 14 kWh residential battery system will probably be within the vary of ,000 to ,000 earlier than the state-specific incentives, which hold prices down for the typical house owner. . Lithium can also be an inherently flammable materials that may make batteries extra of a legal responsibility than an asset.

Lithium battery fires are sizzling and quick, and tough and harmful to place out. Burning batteries additionally emit varied poisonous gases which can be dangerous to folks and the setting. Whereas it is true that California wants battery storage, it must evolve past lithium for mass adoption to fulfill the dimensions wanted.

The subsequent wave of unpolluted expertise adoption ought to make the most of batteries which can be inherently protected and inexpensive. Non-lithium alternate options to power storage exist, and lots of extra are at the moment being developed. These new battery applied sciences will assist California be certain that NEM 3.0 doesn’t adversely have an effect on the clear power transition, and as an alternative kick it into excessive gear.

As soon as deployed at scale, these new battery chemical substances will function beneficial property to assist form the clear and sustainable energy grid of the longer term. Like photo voltaic panels earlier than underneath the earlier NEM coverage, the batteries reply and are rewarded for offering power again to the grid when it’s wanted.
