A strategic approach to energy procurement can strengthen financial stability, reduce risk, support sustainability efforts, and improve overall competitiveness. A well-designed procurement strategy enables homeowners' associations and housing corporations to respond confidently to market volatility while achieving their operational and environmental goals.
As an experienced energy partner, ista understands the challenges of today's complex energy market. In collaboration with FLINK, we offer efficient access to suppliers, transparent market information, and expert advice to help you decide where, how, and when to purchase energy, so that every decision contributes to long-term cost efficiency and resilience.
Choosing the right contract is essential to finding a balance between cost stability and market opportunities. The right choice depends on the energy profile and financial objectives of your building.
A fixed-price contract sets an agreed rate for the entire term of the agreement. This offers complete price certainty and enables accurate budgeting, eliminating the risk of fluctuating market prices. The supplier assumes the market risk, which is reflected in a small surcharge. Fixed contracts are ideal for organizations that value stability and predictable costs over flexibility.
Variable price contracts are adjusted regularly—often monthly—based on the supplier's pricing models. Although these contracts are easy to manage, they offer limited transparency and are influenced by short-term market fluctuations. They are suitable for buildings with stable consumption patterns, but active monitoring is required to prevent unexpected cost increases.
In indexed contracts, the energy price is directly linked to a published market index. Customers pay the real-time market price plus a supplier margin. While this model offers complete transparency and can reduce costs when prices fall, it also makes customers vulnerable to market fluctuations. Therefore, indexed contracts are best suited for customers who actively monitor the market and can adapt to changing conditions.
This hybrid model offers a combination of security and flexibility. Part of the required energy is purchased at a fixed price, while the rest is priced according to the market index. This balanced approach enables customers to manage risks and benefit from favorable market movements, while the contract is tailored to their usage profile and financial objectives.
Green energy contracts guarantee that part or all of your energy comes from certified renewable sources, such as wind, solar, or hydroelectric power. These contracts can be structured as fixed-price or indexed contracts. They are ideal for homeowners' associations (HOAs) and companies working toward sustainability goals or Environmental, Social, and Governance (ESG) reporting, offering environmental benefits and reputational value.
Energy procurement involves negotiating and concluding supplier contracts on behalf of a homeowners' association or housing association. ista and FLINK take care of the administrative work and ensure compliance with Dutch laws and regulations.
By bundling the demand from many buildings, we create bargaining power that individual homeowners' associations or housing associations cannot achieve on their own. Our experts then conduct a transparent tendering process with trusted suppliers to guarantee the best terms and conditions.
