Power Bond 3 – 8.5% p.a. secured fixed-rate bond


This offer has now reached capacity.

Co-invest with Corylus Capital (formerly Hazel Capital) in a series of containerised batteries and engines that help the National Grid with the peaks and troughs of energy demand and supply. 

This is a six-year amortising bond. It offers an 8.5% p.a. fixed rate of interest as well as capital repayments from the end of year one. By the end of year two you should get back nearly half the original investment, in addition to the interest. Returns are not guaranteed. 

Previous Power Bonds have been extremely popular. Of the four previous projects managed by Corylus Capital, only the first was available to the open market. The subsequent three were all funded privately.

We expect the current offer to fill quickly. Of the £8.5 million fundraising target, £6 million has already raised been raised before the official open date. 

Important: The information on this website is for experienced investors. It is not advice nor a research or personal recommendation to invest. If you’re unsure, please seek advice. Investments are for the long term. They are high risk and illiquid and can fall as well as rise in value, so you could get back less than you invest.

How much could you receive? 

The bond aims to pay fixed interest of 8.5% p.a. over a six-year term. 

This is an amortising bond, so, instead of having to wait until the end of the term to receive your capital back, you get it gradually over the course of the six years. 

The table below shows illustrative returns for different investment amounts. 

For each year you can see how much you could receive, both in interest and capital repayments. As you will notice, by the end of year two you should receive back nearly half the amount you invest. 

Please note: these returns are illustrative and not guaranteed.Power Bond 3 illustrative returnsThe figures above refer to the period from the bond Commencement Date to the end of each year.

How are the funds used?

Corylus Capital has commissioned the construction of a 20MW energy storage and generation project – a series of containerised batteries next to a solar farm near Melksham, Wiltshire. 

The construction has been completed and the total cost was £12.5 million. Corylus Capital and other private investors are covering £4 million of these costs. The funds raised through Power Bond 3 should cover the balance (£8.5 million). 

The plant is connected to the National Grid and helps it manage the peaks and troughs of energy demand and supply. In simple terms, the batteries collect and store any excess electricity the solar farm produces and release it into the grid when needed. It has been generating revenue since 1 May 2018 and has already a contract with the National Grid. 

What protection do Power Bond holders have?

The cash flow from the project is scheduled to fully cover interest payments. However, should things not go to plan, Power Bond 3 offers protection to investors:

  • Power Bond holders have priority over all other lenders, including the manager, Corylus Capital.  No other distributions or loan repayments shall be made until full repayment of the Power Bonds. 
  • The cost of the equipment provides significant asset-backing. Engines, batteries, inverters and other electrical equipment can be easily removed and reused elsewhere and are worth more than £8.5 million, the amount of the Power Bond.
  • The loan-to-value ratio based on the Power Bond amount and the net present value of the Project is estimated at 42.5%.
  • Even in the most pessimistic scenario, the project's present value is considerably greater than the Power Bond amount.
  • Around 80% of the project's revenues are expected to be contracted. This means they should not be affected by any fluctuations in energy prices. 

Please remember, though, this is still an investment, so returns are not guaranteed and capital is at risk. So it should only be considered by experienced investors who can afford to potentially lose their money. The Power Bond is not covered by the Financial Services Compensation Scheme.

What experience does the manager have?

This is the fifth project of this kind managed by Corylus Capital, an experienced investment manager and developer specialising in clean energy technologies. The team will be led by Ben Guest, who has over 20 years of experience.

The first project was funded through the first iteration of the Power Bond in 2016. It was extremely popular with Wealth Club clients. So far it has paid all interest as planned. The subsequent three projects were all privately funded before they reached the open market. 

All sites are performing and operating in line with modelled expectations since being commissioned and energised. Please note, though, the performance of similar previous projects should not be taken as a guide to the future performance of the current project.


This is an illiquid and not readily realisable investment for experienced investors only. Capital is at risk. You should not invest money you cannot afford to lose.

The bond is not transferable and cannot be traded on any secondary market. The bond is not covered by the Financial Services Compensation Scheme.

Interest is paid net of 20% UK withholding tax (currently 20%). Tax rules can change and tax benefits depend on circumstances.

Our view

We believe this is a compelling asset-backed and contract-backed offer with a realistic prospect of good returns. 

The management team can demonstrate an excellent track record and has considerable vested interest in the success of this project: it is investing £4 million, which can only be repaid after Power Bond holders have received their interest and capital heavily invested in the Project themselves.

Whilst this is a 6-year investment, almost half of investors’ capital should be repaid by the end of the second year which could provide a quick return on capital. 

Overall, we see this as a good fixed-rate investment opportunity for experienced investors, but you should form your own view.
