TESLA POWERWALL 2.0 FOR STABILIZING DISTRIBUTION GRIDS

TESLA POWERWALL 2.0 FOR STABILIZING DISTRIBUTION GRIDS

 

Tesla markets a wall-hung, 14 kWh Powerwall 2.0 battery unit, with lithium-ion cells made by Panasonic, either in Japan or Nevada. The unit is designed for daily charging and discharging.

 

The turnkey cost of the unit = $6,200, factory FOB + S & H + Contractor markup of about 10 percent + Misc. hardware + Installation by 2 electricians, say 16 hours @ $60/h = $8,200, or $586/kWh of battery…

COMPARISON OF RECENT BATTERY SYSTEM TURNKEY CAPITAL COSTS

The turnkey capital cost of battery systems has been decreasing the past few years. The below table has turnkey capital costs/kWh of some 2016 and 2017 projects. Subsidies, such as cash grants, discounts, investment tax credit, ITC, and 5-year accelerated depreciation, which serve to reduce the cost/kWh, were ignored.

TESLA POWERWALL 2.0 FOR ENERGY STORAGE AND DEMAND REDUCTION

Tesla markets a wall-hung, nominal 14 kWh, available 13.5 kWh, Powerwall 2.0 battery unit, with lithium-ion cells made by Panasonic, either in Japan or Nevada. The unit is designed for daily charging and discharging.

 

Battery system turnkey capital cost = $6,200, factory FOB + S & H + Contractor markup of about 10 percent + Misc. hardware + Installation by 2 electricians, say 16 hours @ $60/h = $8,200, or $586/kWh. 

 

This is a Tesla estimate, which…

THE TRAVESTY OF US SOUTHEAST WOOD PELLET EXPORTS TO EUROPE

The EU and US have declared, “Burning wood is CO2-neutral”. East Europe and the US Southeast still have significant areas with forests. Starting about 2005, major parts of these forests have been harvested by means of clear-cutting. In 2016, about 6.5 million metric ton of wood pellets will be shipped from the US Southeast to Europe for co-firing in coal-fired power plants. The EU authorities in Brussels have declared these coal plants in compliance with EU CO2/kWh standards, because biomass…

THE WORLD MAKING ALMOST NO PROGRESS TOWARDS RENEWABLE ENERGY

World Electricity Sector

Worldwide investments in electricity generating plants and grid systems were about $10 trillion, of which about $6.52 trillion for electricity generating plants and about $3.46 trillion for grid system upgrades during the 2000 - 2016 period.

 

Worldwide investments in renewables electricity generating plants were about $4.2 trillion, of which about $3 trillion for electricity generating plants (wind, solar, hydro, bio, etc.) and…

"90% RE OF ALL PRIMARY ENERGY BY 2050" EXPENSIVE FOR VERMONT

Vermont Senator Bray is being pressured by the starry-eyed, "90% RE by 2050" folks (the latest trend is 100% RE, a nice round number). Many of those RE folks, a.k.a. "stakeholders" are looking to cash in as much federal and state subsidy money as possible, as quickly as possible. They use the mantra of fighting climate change, global warming and job creation. Other RE folks likely have near-zero experience in the analysis of energy systems.

 

Accordingly, Senator Bray, eager to…

WORLD LAND AREA NEEDED FOR REPLACING FOSSIL FUELS WITH BIOFUELS

For the past 200 years, we have multiplied from 1.0 billion in 1800 to 7.4 billion in 2016, and will multiply to a likely 9.5 billion by 2050.

 

Most of them have lived the good life, courtesy of our fossil fuel inheritance. Transitioning to biofuels is like having to get a real job and work for the annual yield, year after year; a yield subject to the vagaries of the weather.

 

No more freebees from nature that were just lying around for millions of years waiting…

VERMONT SPECIAL INTERESTS WOULD GRAB THEIR SHARE OF THE CARBON TAX

Vermont’s proposed carbon tax is as described in this URL. Proponents claim the carbon tax would be 90% “revenue neutral”, i.e., mostly returned to the economy likely in convoluted ways, via inefficient, ponderous, government programs in the form of “targeted” tax credits, subsidies, rebates, grants, etc. There would be taxpayer and employer tax rebates, but amounts and eligibility were not specified.…

REVIEW OF "THE 100% RE BY 2050 PLAN FOR THE US" BY THE JACOBSON GROUP

This article has two purposes:

 

- A review the “100% RE by 2050 Plan for the US”, which is based on wind, solar and miscellaneous. for ALL of US primary energy, as presented in the Jacobson Group Report, issued in May 2015

- A presentation of two alternatives, which include wind, solar, hydro, nuclear and bio energy.

 

In the past, the Jacobson Group has published similar reports regarding for New York State, California, and the Whole…

Hannah Pingree on the Maine expedited wind law

Hannah Pingree - Director of Maine's Office of Innovation and the Future

"Once the committee passed the wind energy bill on to the full House and Senate, lawmakers there didn’t even debate it. They passed it unanimously and with no discussion. House Majority Leader Hannah Pingree, a Democrat from North Haven, says legislators probably didn’t know how many turbines would be constructed in Maine."

Maine Center For Public Interest Reporting – Three Part Series: A CRITICAL LOOK AT MAINE’S WIND ACT

******** IF LINKS BELOW DON'T WORK, GOOGLE THEM*********

(excerpts) From Part 1 – On Maine’s Wind Law “Once the committee passed the wind energy bill on to the full House and Senate, lawmakers there didn’t even debate it. They passed it unanimously and with no discussion. House Majority Leader Hannah Pingree, a Democrat from North Haven, says legislators probably didn’t know how many turbines would be constructed in Maine if the law’s goals were met." . – Maine Center for Public Interest Reporting, August 2010 https://www.pinetreewatchdog.org/wind-power-bandwagon-hits-bumps-in-the-road-3/From Part 2 – On Wind and Oil Yet using wind energy doesn’t lower dependence on imported foreign oil. That’s because the majority of imported oil in Maine is used for heating and transportation. And switching our dependence from foreign oil to Maine-produced electricity isn’t likely to happen very soon, says Bartlett. “Right now, people can’t switch to electric cars and heating – if they did, we’d be in trouble.” So was one of the fundamental premises of the task force false, or at least misleading?" https://www.pinetreewatchdog.org/wind-swept-task-force-set-the-rules/From Part 3 – On Wind-Required New Transmission Lines Finally, the building of enormous, high-voltage transmission lines that the regional electricity system operator says are required to move substantial amounts of wind power to markets south of Maine was never even discussed by the task force – an omission that Mills said will come to haunt the state.“If you try to put 2,500 or 3,000 megawatts in northern or eastern Maine – oh, my god, try to build the transmission!” said Mills. “It’s not just the towers, it’s the lines – that’s when I begin to think that the goal is a little farfetched.” https://www.pinetreewatchdog.org/flaws-in-bill-like-skating-with-dull-skates/

Sign up today and lend your voice and presence to the steadily rising tide that will soon sweep the scourge of useless and wretched turbines from our beloved Maine countryside. For many of us, our little pieces of paradise have been hard won. Did the carpetbaggers think they could simply steal them from us?

We have the facts on our side. We have the truth on our side. All we need now is YOU.
