UK to stop subsidies for sub 5MW solar parks and to change its FiT scheme

UK to stop subsidies for sub 5MW solar parks and to change its FiT scheme

The UK’s Department for Energy and Climate Change (DECC) has announced today that it wants to scrap its Renewable Obligations (ROCs) subsidies for sub 5MW solar farms from April 1, 2016, one year earlier from what was originally planned. Other changes include the removal of pre-accreditation from the Feed-in-Tariff (FiT) scheme for PV installations larger than 50 kWp.

Rooftop mounted PV: new trend for investors in the UK

Rooftop mounted PV: new trend for investors in the UK

As the UK is transitioning from the Renewable Energy Obligation scheme (ROC) to the Contract for Difference scheme (CfD) for large ground mounted systems (5MW+), investors are becoming increasingly investing in rooftop mounted PV.

American Utilities Predict Their Own Downfall

It has been predicted that solar power may be a significant hindrance on the electric utility industry… by an electric utility company. In January, a report that went fairly unnoticed by the media was published by the Edison Electric Institute (EEI). The EEI is an association of American share-holder owned electric power companies. The report predicts that as more customers opt for distributed energy resources (DER), specifically photovoltaics (PV), the US electric utility industry could be destroyed. A similar situation has already occurred in Germany and now the US is predicting the same downfall.

American Utility Background

The electrical utility industry is an old system that has been mostly unchanged since its establishment. There are two main types of utilities:

1. Regulated monopolies that generate electricity in a power plant and then sell and provide it to consumers through the power lines within their service area.

2. Deregulated utilities manage a grid that consumers are connected to. However, it is separate from power generation plants so they must buy energy from the market and then provide it to consumers through their grid.

A utility first has to present its case to the public utility commission (PUC) by stating how much electricity they have to produce (or purchase) based on consumer demand for electricity as well as the rates they want to charge for the power. When the PUC accepts their rates, they also guarantee the utility a reasonable return on power investments and grid upkeep.

The electricity utility business model is quite an old and accustomed one. It relies on high demand for electricity and selling this electricity to make a profit. With higher demand for electricity, investments also increase and thus, lead to greater profits for utility shareholders.

Essentially, utilities thrive as they sell more power which could lead them to oppose energy efficiency and demand response programs such as incentives to lower electricity use during peak hours. The ability for solar power to be at its strongest close to peak times also affects utilities’ profit-making mechanisms. PV systems on residential and commercially-owned rooftops are not owned by the utilities so power produced by the PV (or any other DER) is not being returned to the utility as profit. Rather, each kilowatt produced by PV energy is reducing demand for utility produced energy. Power during peak hours are the most expensive and utilities can generate the most profit during this time. Yet, as solar also reaches its maximum near this time, it takes away much of the profit utilities could be making during the peak hours.

Vicious cycle downwards

Normally, the cost of investment and maintaining the grid are placed on ratepayers within the service areas. However, as consumers start to opt out of the grid and produce energy independently, the costs will be placed on a smaller group of ratepayers. When this occurs, the rate for the remaining ratepayers increases and damages the utility’s credit rating. As the rate increases, consumers will switch to DERs such as PV energy. The EEI forecasted up to 20% increase of rates for people without solar energy. This is a vicious positive feed-back cycle that could change how utilities function in America. Solar energy is directly interfering their profit mechanisms, however, utility investors seem to be paying little attention to this issue.

The inevitable changes in a fairly old business model were also compared to the changes experienced by some companies like Kodak and the US Post. However, unlike most companies, electricity utilities are unaccustomed to constant changes in the market and have benefited from a fairly untouched market until now. The EEI report discusses ways to avoid these issues mostly by revising their own tariff structures and by planning for “disruptive challenges” like PV. EEI presents measures to maintain the old business model and the utilities. However, is that what consumers also want or will we soon see the downfall of a possibly outdated industry?

Are you searching for a rooftop for a PV installation?

Milk the Sun is not only a marketplace for PV installations and PV rights, but we also offer our customers a comprehensive and consolidated photovoltaic stock market. On our online platform you can find an appropriate area for your projects, subdivided into ground mounted and rooftop mounted.

You can specifically look for a slanted roof or a flat rooftop of your choice, by deploying the following search options in our PV Installations and Project List overview:

As a result you receive an overview of suitable photovoltaic rooftop areas, with help of which you can already review the relevant parameters about specific rooftop areas. In order to find out more details about a specific rooftop area and to potentially rent it, click on the preview picture or on the magnifying glass icon:

On the detailed preview website you find all information accessible free of charge, inclusive of payment method. Some owners sell others rent their rooftops. In both cases a single payment is possible; however in case of a rental a monthly instalment is more commonly accepted.

Please notice however, that when you are registered you receive more information free of charge than unregistered users. Therefore, we strongly encourage you to log in under this address: , before you start your search. In case you do not own an account yet, you can register yourself free of charge on the same website!

Moreover, through using the tabs, you receive further information about the chosen rooftop e.g. about the length and width of the area. Also here the same principle applies – when logged in, you see more. You just simply have to register once, free of charge.

Before you can rent a rooftop or purchase a project right, you have to unlock the missing data. In order to do that, click on the big icon of a lock in the left column:

At this point we charge a protection fee of 8 EUR for the activation. Afterwards, you can directly contact the owner. With the online stock market for the photovoltaic of Milk the Sun, you can find appropriate areas for your planed PV installation all over Europe.
