Tesla batteries could serve as back up for Massachusetts wind farm
Tesla batteries could be used as energy storage for a wind farm off the coast of Massachusetts.
Deepwater Wind LLC is looking to partner with Tesla for the 144-megawatt project, as reported by Bloomberg. The company will bid with the state of Massachusetts to build offshore wind turbines that would provide clean energy during peak hours.
The facility would help supplement the power grid by charging up late at night and delivering power during high volume times, according to Deepwater Chief Executive Officer Jeff Grybowski.
National Grid Plc, Unitil Corp. and Eversource Energy — three Massachusetts utility companies — are requesting $9.45 million of clean energy and have opened bidding from solar, hydroelectric and wind companies, as well as other forms of clean energy.
The power companies need supplemental power mainly during winter evenings.
“Those hours are very valuable to the grid,” said Grybowski. “The battery will ensure that we can do that.”
A decision won’t be made until December, and bids are expected to be made public sometime this week.
For Tesla, this project falls directly in line with other Powerpack outfits around the world. The company already has a massive battery operation underway in Australia, and its massive solar plant in Hawaii was created to serve a similar function.
The Massachusetts project, should Tesla and Deep Water Wind win the bid, would only require a 40 MWh storage system. This storage capability would be smaller than the 52 MWh system Tesla has set up on Kauai and the 100 MWh system that will be installed in southern Australia.

Deepwater Wind Proposing World’s Largest Offshore Wind, Energy Storage Combination
Revolution Wind Farm Bid into Massachusetts Clean Energy RFP
New Bedford, Mass. – July 31, 2017 – Deepwater Wind today unveiled plans for its newest project off the American coast: Revolution Wind, a utility-scale offshore wind farm paired with an energy storage system.
“Revolution Wind will be the largest combined offshore wind and energy storage project in the world,” said Deepwater Wind Chief Executive Officer Jeffrey Grybowski. “People may be surprised by just how affordable and reliable this clean energy combo will be. Offshore wind is mainstream and it is coming to the U.S. in a big way.”
Deepwater Wind is proposing the 144-megawatt Revolution Wind farm – paired with a 40 megawatt-hour battery storage system provided by Tesla – in response to the Commonwealth’s request for proposals for new sources of clean energy in Section 83D of the Act to Promote Energy Diversity. Deepwater Wind also provided alternative bids for a larger 288 MW version of Revolution Wind and a smaller 96 MW version.
“Revolution Wind is flexible and scalable. That’s a serious advantage of offshore wind – we can build to the exact size utilities need,” Grybowski said. “We can build a larger project if other New England states want to participate now or we can start smaller to fit into the region’s near-term energy gaps. And our pricing at any size will be very competitive with the alternatives.”
Deepwater Wind also announced that it will be the first offshore wind company to base construction and operations in the City of New Bedford, Mass. The company will locate final turbine assembly and staging operations at the New Bedford Marine Commerce Terminal. In addition, Revolution Wind’s long-term operations and maintenance center will be in the City. Together, this project will create hundreds of local jobs in the Commonwealth.
Revolution Wind’s offshore wind-battery storage pairing will allow the Commonwealth to meet two policy goals. First, by reliably delivering clean energy – backed up with energy storage – during the times when the grid needs it most, Revolution Wind will help to defer the need to construct costly new peaking generating facilities and controversial transmission lines.
Second, Revolution Wind will advance offshore wind development in Massachusetts by providing an avenue to launch the new industry with an initial smaller-scale project, and phase in larger projects in close succession. This way, the Commonwealth’s ratepayers will benefit from increased competition and declining costs, and the regional supply chain will steadily mature.
At 144 megawatts, Revolution Wind could be built in a single construction season, and developed more cost-effectively, and with considerably less risk, than a larger project.
Deepwater Wind will build Revolution Wind in the company’s federal lease site off the coast of Massachusetts. The site is located 30 miles from the mainland and about 12 miles south of Martha’s Vineyard. The wind farm will be adjacent to Deepwater Wind’s South Fork Wind Farm, a 90 MW project serving Long Island. Fully-built, the lease site has the potential to host 2 gigawatts of offshore wind energy.
If approved, local construction work on Revolution Wind would begin in 2022, with the project in operations in 2023. Survey work is already underway at Deepwater Wind’s lease area.
Deepwater Wind also intends to submit an offshore wind proposal under Massachusetts’ separate 83C offshore wind RFP; those bids are due in December 2018.

Tesla Semi factory is getting a celebration nobody expected
Tesla will inaugurate its Nevada Semi factory September 24, five months after production quietly began ramping.
Tesla says it will officially inaugurate its new Semi factory in Nevada next month. The Tesla Semi account posted the announcement on X, sharing a graphic titled “Semi Rollout” with a date of September 24. No further details were given about the format of the event or who would attend.
While Tesla’s dedicated Semi plant in Sparks, adjacent to Gigafactory Nevada, opened back in April, with the first trucks rolling off the high volume line on April 29, the timing for the factory inauguration comes at a surprise. The ribbon cutting event five months into production is a break from how Tesla has usually handled its other factories, where the first truck or car off the line typically served as the milestone moment.

The 1.7 million square foot factory was built as part of a $3.6 billion expansion Tesla announced in early 2023, and it shares a site with the battery cell lines that feed the Semi’s structural pack, a decision meant to remove the supply bottleneck that delayed the truck for years. The plant is designed for 50,000 trucks a year at full ramp. Semi program director Dan Priestley has said production “is now ramping” rather than claiming it has reached scale.
Nine years passed between the Semi’s 2017 unveiling and this stage of production, with the truck slipping from an original 2019 target through hand built pilot units for PepsiCo and a slow build out of the Nevada plant. An inauguration event now gives Tesla a stage to talk up that ramp and reset expectations for how many trucks it can begin delivering at scale.
The September date also lines up with the Semi’s next milestone. Tesla confirmed the truck is heading to Europe with a full unveiling at the IAA Transportation trade show in Hannover, Germany, running September 15 through 20. Between the Nevada event and the Hannover reveal, Tesla has roughly a week and a half in September to make the case that the Semi is now a truck being built and sold on two continents rather than tested in a handful of fleets.
Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.
Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.
Tesla announces 100k Powerwalls are participating in Virtual Power Plants
Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Inside Tesla’s secretive $10 Billion “Project Crystal Sun” filing
Tesla filed for a $10.1 billion Fort Bend solar factory, but the site isn’t confirmed.
Tesla has filed paperwork in Texas for a second massive manufacturing project in the same week it locked down its chip fabrication site, this time for a $10.1 billion solar cell plant in Fort Bend County. The filing, submitted July 22 under the state’s Jobs, Energy, Technology and Innovation Act and first surfaced by Sawyer Merritt on X, lists an internal project name of “Project Crystal Sun” and targets a site off FM 762 and FM 1994 near Richmond, about 40 minutes outside Houston.
Tesla is planning to build a $10.1 billion vertically integrated solar cell manufacturing facility in Fort Bend County, Texas, about 40 minutes from Houston, according to a new public application filing.

The application, prepared by Kroll Tax Services on Tesla’s behalf, spans five parcels totaling roughly 3,000 acres within the Lamar Consolidated Independent School District. Tesla wants a 10 year property tax limitation in exchange for the investment, split as $1.5 billion in real property and $8.6 billion in equipment and personal property. The company projects 9,712 permanent jobs once the plant reaches full operation, with 1,147 peak construction jobs during a build window running from this year through 2028 and commercial operations targeted for the first quarter of 2029.
Tesla is not fully committed to Fort Bend County yet. The filing states the company is weighing the site against an unnamed out of state alternative, and frames the tax abatement as what would make Texas competitive against that option. If the district and county decline the incentive, Tesla says it may build elsewhere.
Tesla Megapack Megafactory in Texas advances with major property sale
The plant would handle the full solar cell production chain in one facility, according to the filing, covering wafer and ingot manufacturing, coating, metallization and printing lines, cell testing, automated material handling and cleanroom infrastructure. That scope points to Tesla vertically integrating a part of its supply chain it currently sources largely from overseas partners, mirroring the approach behind its expanding Megapack production in Brookshire, Texas, where Tesla has already built out two buildings for its grid battery business.
The timing lines up closely with Tesla and SpaceX’s other big Texas commitment this month. SpaceX confirmed its Terafab chip factory would land in Grimes County days before this filing surfaced, with construction on that $16.8 billion project starting almost immediately after local officials met with residents. Terafab is meant to produce the AI chips running Tesla’s Optimus robots and Full Self-Driving software, while a solar cell plant would feed a different part of the business, the panels and storage systems Tesla sells to homeowners, businesses and utilities, and increasingly needs to power its own data centers.
Musk has talked about building domestic solar manufacturing capacity before, tying it to the amount of power Tesla’s AI ambitions will require.
