Energy Storage Contracting. No upfront investment.

The energy storage market and technology are relatively young and often lack the practical experience. Do the products stand up to the data and facts in the marketing brochures?

Especially for commercial applications of power storage or combinations of power storage and photovoltaic, the economic return is seen as primary goal!

Energy Storage Contracting is the answer to the key question of how economical a power storage can be for business applications.

Contracting? What is behind it?

Simply put, you do not buy a power storage but rent it over a certain period of time. Best is, you can fully use the storage capacity from the beginning of the contract.

Comparable with the real estate market, the apartment is not bought, but rented.

Upon request, a purchase option is also possible with contracting offers.

The goal of electrical energy storage contracting is that the customer has higher economic returns than costs from the beginning. Energy storage generates profits every minute without having to anticipate tedious investment scenarios in advance.

Risks of a working system are transferred from the customer (as it would be with standard investments) to the contractor. The customer makes profit with his electricity storage from the first hour and has no risks.

To be too good to be true?

Commercial Energy storage applied at farms

Especially for agricultural businesses, energy consumption can be optimized through contracting solutions. Smart system controls allow electronic consumers to be perfectly coordinated and coordinated.

This is how power storage contracting by storage specialist BlueSky Energy are working.

Define the current need and energy status. This is the first step. Which energy storage in which size is required? The following points will need to be defined on-site:

  • Island mode or emergency backup functionality needed

  • Intelligent energy management system – with functionality needed

  • Photovoltaic available or additionally required? What is the consumption in kWh?

All this base data is coordinated to make a professional power storage or energy offer.

Establish reference costs

What is the current electricity consumption / energy costs currently? How much will they rise in the next few years? These are the reference costs or actual costs, which the customer pays. How can you optimize with a power storage?

Define contracting details

Solar storage specialist BlueSky Energy prepares customised contracting offers for you. Savings for conventional solutions are defined as well as costs of contracting, terms, bilateral rights and obligations, warranties and guarantees.

Installation, save costs …

If you like your contracting offer, there is nothing standing in the way of implementing the electricity storage project and saving costs.

Frequently asked questions in respect to energy storage contracting:

The saltwater electricity storage – GREENROCK – a few facts

  • GREENROCK energy storage is neither flammable nor explosive. It consists of non-toxic materials. Therefore, there is no special construction requirements in respect to building or housing. There are no additional costs for structural or transport-technical requirements.

  • GREENROCK can be 100% deep discharged (100% DoD) and offers 3000 cycles when fully discharged. The saltwater electricity storage tank can continue to operate without risk even after the 3000 cycles. Only the storage capacity is reduced. Over the entire life cycle, 1 kWh storage capacity of GREENROCK achieves an energy throughput of 4,300 kWh.

  • The temperature range for operating the salt water storage tank is between 0 ° C and 45 ° C.

  • With integrated energy management system (EMS) and integrated electronics GREENROCK is a compact, intelligent and ready to connect complete system. Easy to install, maintenance-free during operation. EMS offers many possibilities to easily integrate and optimize power consumers.

Contracting facts based on a real-life example

Application installation in Austria. Investment in 60 kWp photovoltaic and 60 kWh electricity storage.

Investment total, net – without subsidies 114.000,– EURO
Current electricity costs/kW 0.15 EURO
Contracting fee/year 10.400,– EURO
Yield/year on average 11.377,– EURO
Profit/year 977,– EURO

* Revenue from electricity cost savings assuming that the electricity price remains the same, any increases in the electricity price lead to increases in income and tax deductibility of the contracting fee with an assumed tax rate of 25%

General information about energy storage contracting and leasing solutions

1. Electrical energy storage leasing

The energy storage is in the property of the customer. Similar to car leasing, the customer does not pay the investment immediately, but via ongoing leasing instalments. With payment of the last leasing rate, the electricity storage device becomes the property of the customer.

Responsibility for operating the electricity storage system lies with the customer.

Advantages for the customer: The customer can immediately use the financial income from the electricity storage, and paid the money for the purchase of electricity storage for years in small amounts.

2. Energy Contracting (Equipment Contracting)

The electricity storage is the property of the seller, who operates the electricity storage for the customer. The customer receives a defined performance, e.g. 100 kWh of electricity storage capacity provided. The responsibility operating the electricity storage lies with the seller.

The customer must provide or guarantee appropriate premises and conditions (connection options, room temperature etc.).

Advantages for the customer: The customer pays according to defined, provided capacity (for example electricity storage capacity). If the service is not delivered, the risk lies with the contracting dealer / seller.

3. Contracting (Energy Saving Contracting – Performance Contracting)

The electricity storage is the property of the seller, who operates the electricity storage for the customer. At the beginning, the actual state of the customer is defined e.g. a customer paying for 10.000 kWh 1.500, – EURO.

An analysis of savings potential is defined. A certain percentage of the savings go to the customer, the rest goes to the contracting giver.

The advantage for the customer is a fixed cost reduction without having to make additional investments.
