In recent years, many agricultural companies have started investing in their own systems for generating energy from renewable sources such as photovoltaics or wind. But, even if your entire electricity supply comes from the grid, it may be worth investing in a battery storage system for your company’s operations. This will permanently reduce your energy costs and give you greater independence from your supplier.

Our TESVOLT storage systems reliably provide you with a reliable way of getting energy whenever you need it at an affordable cost. Store the electricity you generate yourself when you don’t need to consume it or use it when your installation is producing little or no energy. Cut high grid connection costs by investing in a large PV installation. Charge the storage system during periods of low power consumption and avoid peak loads during busy periods . Use your storage system to back up important installations, e.g. for ventilation or cooling, or against power failures.

Whether your business involves growing crops, farming livestock or producing dairy, an investment in a TESVOLT battery storage system will both pay for itself in next to no time and protect you against rising energy prices in the long run.

Agri-photovoltaics (Agri-PV) allows farmland to be used for agricultural production and electricity generation at the same time. Under DIN SPEC 91434, farming remains the primary land use — solar modules are mounted (for example, elevated above special crops or arranged vertically along field edges) so cultivation and harvesting are barely affected.

Under Germany's Renewable Energy Act (EEG), Agri-PV systems qualify as a "special solar installation" and are eligible for an additional remuneration rate — a financial incentive that makes Agri-PV especially attractive. To make full use of that advantage, pairing the system with battery storage is highly recommended: it stores the solar power generated on-site and releases it exactly when the farm needs it — for cold storage, milking equipment, or drying facilities, for example. That significantly increases self-consumption while also flattening demand peaks.

A battery storage system also opens up the option of marketing surplus solar power flexibly — through dynamic electricity tariffs or by trading on the power market — creating an additional revenue stream alongside agricultural production.

Without electricity storage, many farmers only use around 20% of the PV electricity they generate themselves, with the rest fed into the grid. A TESVOLT battery storage system, by contrast, allows you to use as much of the electricity you’ve generated from renewable sources as you want.

This way, you both gain greater independence from the rising prices offered by your energy supplier and save money with every kilowatt hour. Instead of at least 25 cent/kWh for electricity from the grid, a kilowatt hour only costs you 8 to 15 cents – including the purchase costs for your PV installation and storage.

Increase your self-consumption with a battery storage system and protect yourself against rising energy prices.

If your property only has a low connected load, your energy supplier may ask you to pay for feeding in electricity above a certain output level. In this case, it makes sense to use a PV installation purely for self-consumption. If you supplement this zero feed-in system with a storage system, you’ll significantly increase the self-consumption rate, i.e. you will use more self-generated electricity and reduce the amount purchased from the grid.

Electricity prices fluctuate depending on supply and demand. They are often particularly low when renewable energy generation is high or demand is low. The TESVOLT EMS analyses current and forecast prices and shifts electricity consumption and battery charging to lower-cost periods.

External consumers, such as EV charging stations, are also controlled intelligently. This maximises the use of renewable energy, improves energy efficiency and reduces grid electricity costs.

One battery storage system – two ways to create value

Whether you want to cut costs or generate returns, a battery storage system can be used flexibly to match your goals.

With TESVOLT Energy Management, the storage system operates directly behind your meter to reduce energy costs: through self-consumption optimization, peak shaving, and time-of-use strategies — optionally combined with dynamic electricity tariffs such as Tibber or aWATTar.

With TESVOLT Energy, your storage system becomes an investment: the full storage flexibility is marketed on the EPEX spot market or deployed in the balancing energy market — generating stable returns through energy trading and grid ancillary services.

With TESVOLT Energy, your battery storage system becomes an investable asset that actively generates revenue.

You don’t need to fully understand energy trading. TESVOLT Energy manages the entire process — from aggregation and market trading to settlement — while giving you full transparency at all times through the Energy Portal.

01. Aggregate

Your battery becomes part of a pool of TESVOLT systems, forming a shared virtual power plant. The aggregated capacity unlocks access to markets that individual systems could not reach on their own. The more systems in the pool, the more precise the optimization.

From 50 kW / 100 kWh

02. Trade

The virtual power plant is traded on the day-ahead, intraday, and ancillary services markets — fully automated, algorithm-driven, and around the clock. No intervention required from your side.

Fully automated · Day-Ahead & Intraday

03. Monitor & earn

Trading revenues are paid directly to you. In the Energy Portal, you can track performance, revenues, and system status in real time. Full transparency into what was traded, when it was traded, and the revenue it generated. Your system always operates in a grid-neutral manner.
