What does electricity really cost?
The actual cost of grid electricity vs. solar power from your own roof
Energy prices are volatile. Especially for businesses that consume large volumes of electricity, keeping budgets under control remains a challenge. But how much does electricity really cost your business? And what if you generated that same energy yourself through an on-site solar array?
At Solora, we’ve been helping businesses get a handle on their energy consumption and costs for years. In this article, we compare the cost of grid electricity with that of on-site solar power.
Utility Electricity: A Price You Can’t Control
The price of grid electricity for businesses fluctuates significantly. It consists of:
- Energy component: based on the market price (spot market or fixed contracts)
- Grid fee & transmission costs
- Levies and taxes
On average , a business currently pays between €0.20 and €0.30 per kWh —and even more during peak demand. Furthermore, you’re at the mercy of external factors such as geopolitical tensions, CO₂ prices, and seasonal fluctuations.
Your own solar energy: stable, predictable, and cheaper
The cost of solar energy is often expressed as LCOE (Levelized Cost of Energy). For large-scale systems like those built by Solora, it currently ranges between €0.04 and €0.08 per kWh —depending on scale, location, and financing structure.
A few advantages:
- Full control over your energy costs
- Inflation-proof: you generate energy at a constant cost
- Option to integrate with BESS and EMS for even greater optimization
Example: a factory with 1 GWh of annual consumption
Scenario | Consumption Costs | Annual Savings |
| Grid electricity (€0.25/kWh) | €250,000 | – |
| On-site solar farm (€0.06/kWh) | €60,000 | €190,000 |
Note: This does not take into account feed-in restrictions or energy management—with an EMS and battery storage, the return on investment is even higher.
Smart Combination: Solar Array + Battery + EMS
By combining solar generation with a Battery Energy Storage System (BESS) and an Energy Management System (EMS), you can maximize your own consumption, avoid peak demand, and optimize your energy costs.
