Battery Storage

What is Battery Storage?

Batteries allow the user to capture electricity from a renewable system helping to eliminate the intermittency problems associated with solar and wind generation in particular.

A variety of different battery technologies are available including relatively heavy, traditional lead acid batteries with low energy densities to much lighter but more expensive lithium ion batteries with higher energy densities. Lithium ion battery costs have tumbled in recent years and in 2019 were 87% cheaper in real terms than in 2010.

One of the main financial benefits from deploying a battery is from load shifting. This is where excess electricity produced from, for example, roof mounted solar can be used to charge a battery at zero marginal cost ready for discharge when grid supplied electricity is at its most expensive.

The same principle works with a standalone battery which can also help shift demand for grid supplied electricity, with a time of use tariff like Economy 7, when night time electricity is less expensive than during the day.

Batteries can also be used to generate additional revenue streams through the provision of ancillary services to National Grid which help maintain the frequency of the grid at 50hz and provide additional capacity when required.

The main physical constraints to battery deployment are space availability and suitability. Temperature and atmospheric conditions should also be considered as they will have an impact on the life span of the battery.
The three-step process to net zero energy
OnGen offers a three-step process to public sector organisations. Steps can be done holistically or separately.
OnEfficiency

Step 1:

Reduce energy consumption:

With OnEfficiency, we can help you identify where and what you can do to reduce energy consumption and improve energy efficiency.

By becoming more energy efficient, carbon emissions for your organisation will begin to reduce, along with the cost of energy.
OnGen Expert

Step 2:

Consider onsite renewable energy and battery storage:

With the OnGen Expert, we can help you explore the feasibility of generating and storing your own energy via a range of onsite renewable energy generation sources, like solar PV and heat pumps.

Switching to generating renewable energy onsite reduces the demand for grid-supplied energy, lowering the cost of energy bills, gaining resilience to grid fluctuations and reducing carbon emissions.
OnSupply

Step 3:

Switch to zero-carbon energy suppliers:

With OnSupply, we can help you find the cheapest green energy tariffs for any grid-supplied gas and electricity demand.

Eliminate the remaining energy-related carbon emissions for your organisation.

Your organisation will be assigned a dedicated account manager, who will offer training support and guidance. Additionally, if your organisation is struggling for time, the Managed Service, where assessments are conducted by the OnGen team on your behalf, can be a great option.

Case Study

“By assessing solar capability using the OnGen Expert software, we have been able to identify 4,000 tonnes of potential carbon savings in our city-centre building stock. OnGen has made it simple and easy for us to demonstrate potential energy costs savings of £2.9 million across the lifetime of potential onsite renewable installations. The OnGen Expert software has shown us the potential of onsite generation at a fraction of the cost of traditional assessments/consultants.”
