A million dollars to replace blades on a turbine when it pumps out 2mW is hilarious
They don’t cost a million dollars. They make a little more than 2mW.

Funny how insignificant this field is when a CCGT can click a button and raise 200 mw in 10 minutes.
Someone said the blade cost was 200k per. I don’t know if that includes labor. However, say average MWH cost of $30 per hour, it’s going to take a long time to make that up, especially when you can’t generate when you’re seeing these extremely high prices. It would take years to make that up when you produce such an insignificant amount.

Well for starters I would learn the difference between a mW and MW. After that I would leave this up to people who actually know what they’re doing. Wind farms make plenty of money.

If you’re generating 2 megawatts continuously with no shutdown and no factors that don’t allow you to run (wind not blowing) how long does it take you to make up 600k when megawatt prices are ~$30 on average? (They’re $17 right now and it pretty muggy and hot, so traditional power plants are not running super efficiently, and it’s during the day).

100% availability and demand. Probably a little over a year.

What % of the time does a typical wind turbine run? I would assume demand is always there since wind and solar are always the first two to bid into the market. And what % of that are they running at full output?

It depends but a solid average is 45%. That’s up time, blended demand and availability. So that’s 2.5 year ROI. Then it’s an ATM machine for the next 8-12.

287 barrels of oil (equivalent to slightly more crude carried by a single tanker truck) per year to lubricate wind turbines isn’t a massive amount relative to the amount of oil used to heat the city.
New York, going fully electric, would require a revamp of their entire electrical distribution system.

So that’s the only maintenance that goes on is to change the blades every 10 years? So 20% of your income goes to blade changes, and you make 2.5 megawatts, yet it’s an atm? That’s pretty bad when compared to hydro, nuclear, natural gas, and even coal

In all fairness, this could easily be done if "we" chose to invest money domestically instead of the previous multi-decade crusade of "nation building."

There’s some other O&M but not much. They make plenty of money. If you don’t think so, don’t invest in them. I don’t really care.

The grid is mostly privately owned and invested in. It’s not competing for government money to get the work done. It just needs your rates to go up to pay for it.

Funny how a CCGT could absolutely wreck their biggest asset, a steamer, and recover it in about 10 days. It would take a days worth of generation just to cover the cost of a contractor to do monthly NERC testing.

Ok and they still make money. It’s just as easy for me to raise capital for NG, solar, hydro, even nuke now as it is wind. The returns are pretty even even though they are very different profiles.

So what was this about?

The Department of Energy is launching a new Building a Better Grid initiative to accelerate the deployment of new transmission lines—as enabled by the Bipartisan Infrastructure Law—to connect more Americans to cleaner, cheaper energy. This transmission buildout will make our grid more reliable and resilient in the face of intensifying extreme weather and is critical to achieving the President’s goal of 100% carbon pollution-free electricity by 2035.

Probably a loan or they’re trying to own more of the grid. I’d prefer it stay in private hands myself.

Seems to be a large undertaking from the Department of Energy.

BUILDING CLEAN TRANSMISSION LINES
The President’s Bipartisan Infrastructure Law is the largest-ever investment in America’s power grid, including funding to build out thousands of miles of new transmission lines that are critical to unlocking clean energy resources and providing American homes, schools, and businesses with electricity that is more affordable and reliable in the face of extreme weather, wildfires, and other disasters.
To harness the new funding in the Bipartisan Infrastructure Law, today the Department of Energy is announcing a coordinated transmission deployment program, which will catalyze nationwide buildout of long-distance, high-voltage transmission lines. As outlined in a new Notice of Intent, the pillars of the “Building a Better Grid” initiative are:
Financing transmission lines and other grid upgrades, including through the Bipartisan Infrastructure Law’s new $2.5 billion Transmission Facilitation Program, a revolving fund for new, replacement, or upgraded transmission lines; $3 billion expansion of the Smart Grid Investment Grant Program, focused on advanced technologies that increase capacity and enhance flexibility of the existing grid; and more than $10 billion in grants for states, Tribes, and utilities to enhance grid resilience and prevent power outages. DOE will also leverage existing financing, including the $3.25 billion Western Area Power Administration (WAPA) Transmission Infrastructure Program, which facilitates deployment of renewable energy in WAPA’s 15-state service territory, and a number of loan guarantee programs through the Loan Programs Office.
Strengthening coordination with state and local governments, Tribal nations, and other stakeholders, including through participation in regional convenings with independent system operators (ISOs), regional transmission organizations (RTOs), state regulatory commissions, utilities, and others.
Modernizing transmission planning to drive investment to the highest-need projects, including through a new National Transmission Planning Study, National Transmission Needs Study, Offshore Wind Transmission Study, and expanded technical assistance to help states and regions with policy implementation.
Improving permitting processes, in coordination with the Infrastructure Implementation Task Force and other federal initiatives, including by helping developers provide early information to permitting agencies; using public-private partnerships to advance new transmission lines and system upgrades; and designating National Corridors in areas with transmission capacity constraints that harm consumers.
Supporting research, development, and demonstration (RD&D) of next-generation transmission technology, including through collaborations with the National Laboratories and industry partners.
Last year, the Administration laid the foundation for these efforts by revitalizing Department of Energy transmission financing assistance programs and through Department of Transportation actions to help states host transmission lines along public highways and other transportation rights-of-way.

Just due to subsidies, on actual generation, it’s not even in the conversation

I was waiting for this. Break it down for me.
