How are decommissioning costs estimated? Decommissioning costs can vary based on the size of the solar farm. For example,a decommissioning cost estimate for an 80 MW solar farm in Virginia was calculated at$2 million,while a much smaller 50 MW solar farm came in 50% higher-over $3 million.

How much does it cost to decommission a solar power plant?

For example, the engineer’s estimate of the decommissioning of the Water Strider Solar Facility in Halifax County was $2,013,600. The engineer estimated a salvage value of just under $5 million. Therefore the cost of decommissioning was 42% of the salvage value of the site materials.

How much does a solar farm installation cost?

While this cost will vary depending on the specifics of the solar farm project, a reasonable range would be around $1/watt, give or take $0.20 cents. So you can expect it to cost anywhere from $0.80 – $1.20 or more per watt for a large solar farm installation.

How much does it cost to decommission a project?

A letter of credit is a letter from a bank guaranteeing that a buyer’s payment to a seller will be received on time and for the correct amount. In the event that the buyer is unable to make that payment, the bank will be required to cover the full or remaining amount of the obligation.

What is SolUnesco’s recommendation for decommissioning?

First, the estimate should be produced by a licensed engineer. Second, the industry needs to develop standards by which these estimates are created to avoid the wide variation in calculations and thereby restoring trust in the estimates.

What is reserve factor?

A reserve factor to the cost projections to protect against changes in market values; A detailed decommissioning plan with a documented decommissioning costs and salvage value projections. This plan should be either produced by, or reviewed by, a licensed engineer; and.

What security instrument should be included in a building permit?

The financial security instrument should be part of the building permit. Allowable security instruments should be one of the following: performance surety bond; an irrevocable letter of credit; a guarantee by an investment grade entity or another acceptable security.

How much surety bond is required for removal?

The board notes that it reserves the right to require a Surety Bond that is up to 125% of the cost of removal, as well to increase rates of inflation and labor costs as it sees fit based upon market conditions.

What does "decommissioned" mean in solar?

Local zoning boards are requiring that solar developers specifically note how solar power plants will be “decommissioned”: defined as cleaning up the solar power site at the end of its life. Developers suggest that the value of the materials themselves will be greater than the cost of cleanup – and there is some evidence to support this.

How long does it take to remove a panel?

It takes approximately 3 minutes to remove each panel (20 per hour). There are 15,000 panels. You then multiply the hourly cost of the labor needed to remove said panel, times the number of panels removed per hour, and the total number of panels on the job.

Where is the Three Rivers solar plant?

The 100 MWac/126 MWdc Three Rivers Solar Power Plant in Hancock, Maine put costs at 1.8¢/Wdc. The document notes the Maine model is based on New York and Massachusetts data.

Can sureties touch solar?

We look at the strength of the developer, to make sure they’re going to be around to remove these solar power systems – otherwise the surety company becomes obligated to do so. A lot of sureties just won’t touch it if it’s the first solar project. It’s a truth that side gig solar people are tougher to bond.

Is a solar module worth money?

Old solar modules are worth money of course. Recently, modules scheduled for recycling were stolen and sent to Africa to be used by locals. The logic is that it isn’t relevant that the module is only at 80-85% of its original output – since for the new buyer, it still makes electricity. And research suggests that once modules hit that 80% range after a few decades in the field, they tend to stick near that range – meaning 80% output for a few more decades.

Who is John Fitzgerald?

John Fitzgerald Weaver is a solar developer ; known digitally as the ‘Commercial Solar Guy.’ As a project developer and installer, he’s sold and managed 50+ solar projects, valued over $25 million, ranging in size from 5kW to 1500kW. He’s been involved in many aspects of the solar supply chain –- as a company founder, developer, project manager, manufacturer, permit runner, salesman, contractor and financier. In his free time he tries to get away and clear his mind by climbing mountains, or more regularly by enjoying an IPA or scotch, and really loves the strange connection between politics, energy, finance, and environment in the energy world.

What Are They?

Have you ever driven past an open meadow or field crowded with solar panels—acres of them sometimes? Installing such large scale solar energy systems is a major undertaking potentially involving clearing land, putting in an access road, building foundations, laying underground electrical wires, and more.

How Do They Work?

The bond protects the obligee against financial loss associated with three different sources of risk. These three sources of risk are:

What Do They Cost?

The premium the principal will pay for a solar decommissioning bond is a small percentage of the total required bond amount. The surety company will determine the premium rate based on the specific liabilities covered as well as the principal’s personal credit score and business and personal financials. The better the principal’s financial situation, the lower the premium rate.

What is solar decommissioning bond?

A solar decommissioning bond is a surety bond that a project owner will require the contractor to purchase before a solar “farm” is even installed to ensure that someone else foots the bill for decommissioning.

What happens if you don’t have a solar decommissioning bond?

Without a solar decommissioning bond in place from the outset of the project, the private landowner or taxpayers might eventually be forced to pay the cost of restoring the land to its natural state. The bond makes any decommissioning costs the financial responsibility of the utility company, the principal in the surety bond contract.

What is solar farm?

A solar farm, sometimes referred to as a photovoltaic power station, is typically a large decentralized solar array supplying electricity to the power grid. The majority of these massive arrays are owned by utilities and are merely another asset for the utility to supply power to properties in their coverage area.

Can you go solar without putting solar panels on your roof?

The idea of community solar has taken off in recent years as more homeowners have realized that they can go solar without putting solar panels on their own physical roof. A community solar project—sometimes referred to as a “solar garden” or roofless solar —is a solar power plant whose electricity is shared by more than one household. In most cases, a community solar array is a large ground mount installation that spans one or many acres.

What is a solar farm?
