Borrego developed, designed, and built this turnkey solar plus storage project on a formerly capped landfill. The system includes 2 large solar arrays totaling 11.7 megawatts of solar, plus 4 Fluence battery units delivering approximately 26 megawatt-hours of energy storage. This system is engineered with a high DC-to-AC ratio, which enables the system owner, AES, to push more clean energy onto the local electrical grid. The system is expected to generate enough energy to power approximately 1463 homes and offset more than 11,039 metric tons of carbon each year.
LG Energy Solution and Hanwha, two of the major players in global battery and renewable energy technology, aim to establish battery storage-specific manufacturing facilities in the US.
The two South Korean companies have formed a partnership to take on the US battery energy storage system (BESS) market. The market has seen significant growth in the past few years that is expected to accelerate rapidly with the country''s Inflation Reduction Act (IRA) incentivising both deployment and manufacturing of energy storage.
"We have decided to collaborate with LG Energy Solution, which has several large-scale manufacturing facilities being constructed in US, to target the US energy storage system (ESS) market boasting fast growth thanks to green energy policies," Hanwha Group said.
"Our aim is to maximise synergy at home and abroad by promoting partnerships in various fields, such as supplying battery manufacturing equipment and developing special-purpose batteries."
LG Energy Solution (LG ES) has a considerable share of the US market already, supplying battery cells, racks, and complete systems to some of the country''s largest utility-scale BESS projects as well as the residential segment. The LG Group company went publicly listed through an IPO last January.
Last year it made a move to expand further downstream with the establishment of its own system integrator subsidiary, LG Energy Solution Vertech, and the acquisition of a former market-leading system integrator, NEC Energy Solutions.
LG claimed that vertically integrating system integrator and battery cell supply capabilities streamlines the former process and gives customers assurances on a currently constrained global supply chain.
Meanwhile Hanwha Group is currently active in the market through its ownership of Germany-headquartered Qcells, the solar PV manufacturer which also has a range of home batteries and complete home energy management system (EMS) solutions. Qcells bought up US energy storage software and EMS specialist Geli in 2020.
Qcells made its first investment into a grid-scale battery storage project in 2021, acquiring and later selling on the 190MW/380MWh BESS now under construction in Texas'' ERCOT market after securing US$150 million financing.
In September last year it announced three standalone BESS projects in New York totalling 12MW/48MWh with community solar PV and storage developer Summit Ridge Energy.
Last week, Qcells committed to what was claimed to be the US'' biggest private sector investment in clean energy manufacturing. The company announced the construction of 8.4GW of solar ingot, wafer, cell, and module annual manufacturing capacity in Georgia by 2024, with the southern US state already attracting major electric vehicle (EV) and EV battery makers'' investments in the past few years.
With that push and the latest announcement made yesterday, the companies aim to capture the full benefits of the IRA''s incentives, which reward domestic production and deployment of clean energy equipment.
The pair will also work to develop energy storage system products for the commercial and industrial (C&I) and utility markets. For Hanwha, the deal will mean assurances on cell supply and competitiveness on pricing as Qcells targets ramping up of its solar PV and energy storage engineering, procurement and construction (EPC) business in the US.
Other Hanwha companies, such as those active in the aviation and EV industries will also benefit from the partnership with LG ES, the group said.
The news came just a couple of days after LG ES and Japanese carmaker Honda announced a joint venture (JV) to establish around 40GWh of lithium-ion electric vehicle battery production facilities in Fayette County, Ohio by 2025.

Construction is set to begin this spring in Gorham on one of New England''s largest battery storage projects, a preview of similar ventures that are seen as a missing link for optimizing the region''s growing fleet of solar and wind power plants.
Big batteries are considered essential to realizing Maine''s climate goals. That''s because the transition from fossil fuels to renewable power leans heavily on solar and wind — notably from proposed floating offshore wind farms — to help energize an electrified economy.
The problem is, solar and wind are intermittent sources of power. When the sun doesn''t shine and the wind doesn''t blow, other sources are needed to make up shortfalls, and balance supply and demand.
Today those holes are largely filled by ramping up natural gas-fired plants. To replace them, the region will need a robust network of electric sponges to soak up renewable energy when it''s available, and discharge it when and where it''s needed.
Starting in mid-2025, the regional grid operator will be able to dispatch up to 175 megawatts of capacity from the Cross Town Energy Storage facility. The $100 million-plus project will feature 156 tractor trailer-like containers spread across five acres in the Gorham Industrial Park, stuffed with lithium iron phosphate batteries. It''s being built by Houston-based Plus Power LLC, which has 60 energy storage projects online or in development across the United States and Canada.
Cross Town is part of a national trend to build giant battery plants. Growth is reflected regionally by a revealing statistic: Roughly 44% of developer requests to connect to the ISO-New England high-voltage grid now involve batteries, up from 10% just three years ago.
The activity is driven in part by rule changes that went into effect in 2018, which allow battery projects to compete with conventional power plants in the wholesale electricity markets.
More than 1,000 megawatts of new battery capacity has been approved to supply electricity in the next few years in New England. Some batteries are next to solar farms. Others are stand-alone projects, like Cross Town.
Maine has six smaller battery projects up and running, but they''re a fraction the size of Cross Town. That''s why Cross Town may be a model for what large-scale battery storage will look like in the state. And while battery storage has been less controversial than some other energy proposals, three fires in New York state has led to a review of safety practices in the fast-growing industry.
One task is to relieve congestion on southern Maine''s constrained electric grid by absorbing and storing excess energy, as more solar and wind comes online. Cross Town is next to a Central Maine Power substation, giving the batteries a direct connection to high-voltage lines from the north.
Typically, electricity has to be used the instant it''s generated. One obstacle to integrating large solar and wind projects is that grid operators must constantly account for cloudy periods or sudden drops or surges in wind speed. Absorbing and storing excess power from wind and solar can capture energy that might otherwise be wasted on a very sunny or windy day.
Batteries can be deployed in milliseconds. That makes Cross Town valuable for providing what grid operators call ancillary services, such as maintaining the system''s proper frequency standard to keep motors and other electric equipment operating properly. That standard is measured in cycles per second, or hertz.
"It''s like a pacemaker for the grid," said Mark Tourangeau, Plus Power''s chief revenue officer. "It keeps the frequency at 60 hertz to maintain reliability."
Tourangeau also noted that Cross Town and another Plus Power venture won seven-year contracts with ISO-New England during the 2021 annual bid process meant to line up future generating capacity at the lowest prices. The second project is in Carver, Mass.
These batteries can be charged from the grid in the middle of the night, when excess power is available and wholesale prices are low. During periods of peak demand, such as hot summer nights when air conditioners are struggling to keep buildings cool, the stored energy can be released back into the grid. Plus Power makes money by selling during these peaks, when wholesale prices are high. Buy low, sell high. This strategy is called energy arbitrage.
Battery projects have key ratings, including the instantaneous power they can release and the duration they can do it. At 175 megawatts of power capacity, Cross Town can light 175,000 average homes. It''s also rated at 350 megawatt hours, which means it can discharge that much energy running full tilt for two hours.
Two hours might not sound like much time, but because battery plants can turn on and off in an instant, they can be a valuable tool for grid operators.
"Our job is to make sure supply and demand stay in balance on the grid at all times, and two- four-hour batteries can do a lot," said Anne George, a vice president and chief of external affairs and communications for ISO-New England.
In winter, George noted, batteries will play an increasingly important role around supper time, after solar farms have faded out but demand is ramping up as people return home from school and work. It''s notable that next to wind farm proposals, battery storage is what developers are pitching to meet the region''s near-future capacity needs.
"Batteries and wind, that''s pretty much what''s in our queue," George said.
