What is the tenant power tariff?
With the Octopus tenant power tariff, you get green and cheap energy directly from the rooftop of your building – without any detours or installation costs.
And this is how it works:
ZBI and Octopus Energy are installing a solar PV system on your residential building.
This solar PV system generates electricity when the sun is shining.
As an Octopus tenant power customer, the energy generated flows directly from the rooftop into your flat. During these times, you benefit from a super-low solar electricity unit rate.
If the sun isn't shining, you will automatically receive 100% green electricity from the grid via us, easily and without any interruption. When this is the case, our regular unit rate applies.
The tenant power tariff consists of three components:
Solar Power
Particularly cheap unit rate for consumption during sunny hours.
Unit Rate: 
24 ct/kWh
Mains Current
Cheap standard unit rate for consumption during less sunny hours.
Unit Rate:
ca. 29,93 ct/kWh*
Standing Charge
Fixed amount for the provision of your electricity connection, service and maintenance of your smart meter.
Standing Charge:
ca. 13,66 €/month*

FAQs
Tenant power means that electricity is generated directly on site – by a solar PV system on the rooftop of your house. The electricity is then passed on directly to the tenants in the building without having to use the public grid. If more electricity is produced than is needed, the surplus is fed into the grid and can be used by others. And if you ever need electricity from the grid, this is regulated fairly and transparently via Octopus Energy.
Your tenant power tariff works quite simply: the electricity you consume is generated directly on site by the solar PV system on the roof of your building. The more solar power you consume, the cheaper your electricity tariff becomes, as you need less electricity from the public grid. Excess electricity is fed into the grid and made available to the general public. This allows you to benefit from affordable, sustainable electricity while contributing to the energy transition.
Yes, the tenant power tariff is required by law to be at least 10% cheaper than the basic supply tariff. This is mainly because the electricity is generated directly on site by the solar PV system. This eliminates many additional costs, such as the use of the public electricity grid or certain levies. In addition, the production costs for solar power are particularly low, which generally makes the tariff cheaper than other electricity tariffs.
If the solar PV system does not supply enough electricity, the missing electricity is automatically provided from the public grid. Octopus Energy ensures that this additional electricity is environmentally friendly and takes care of the entire supply (residual electricity supply). Of course, all of this is already included in your tenant power tariff.
The tenant power contract usually runs for 24 months. But if you move out, you have a special right of termination! All you have to do is provide Octopus Energy with written proof of your move. We will then automatically terminate your contract on your move-out date – it's easy and there are no additional costs.
We offer tenant power because we believe that sustainable energy should be accessible and affordable for everyone. With the tenant power tariff, you can benefit directly from the solar panels on your rooftop, save money and actively contribute to the energy transition at the same time. It is our mission to work with you to create a greener and fairer energy future.
That's even better, then simply request a quote and indicate in the process that you are an Octopus customer. And best of all: regardless of whether your contract still has a long term or is about to expire, you can switch to the tenant power tariff immediately and without delay.
On the final bill, we show separately how many kWh you have consumed from solar and grid electricity. The respective conditions at the time of conclusion of the contract apply to the different quantities (solar power: 24 ct/kWh, grid electricity: approx. 34 ct/kWh). We also show how much you have saved with our tenant power tariff compared to regular tariffs. Everything is clearly shown on your bill.
ZBI (Zentral Boden Immobilien Gruppe) is a leading real estate group with a large portfolio of apartment buildings. As part of an exclusive sustainability partnership, we at Octopus Energy are working closely with ZBI to actively drive forward the energy transition.
Our goal is to give people who don't own their own homes or have limited financial resources access to affordable, green solar power. To do this, Octopus Energy installs solar panels on the rooftops of ZBI apartment buildings – a necessary foundation for offering you, the tenants, a tenant power tariff.
ZBI provides us with suitable rooftop space on its buildings, while we take care of installing and operating the solar panels. This enables us to work together to offer you green and particularly affordable electricity rates. It's a real win-win-win-win situation: for ZBI, for you as tenants, for the environment and for us.
In order for us to offer tenant power, certain requirements must be met. For example, the building needs a suitable roof for the solar PV system, enough tenants who consume the electricity directly in the same building, and the landlord's consent. Since these conditions are not met everywhere, we can currently only offer tenant power at certain locations. However, we are constantly working on adding more buildings to enable even more people to benefit from affordable solar power.
