Solar Thermal ESCO Contracts

Netgreen.eu OU aims to combine our expertise in the area of Solar Thermal Energy systems and HVAC Design to provide ESCO Services. ESCO contracts for solar thermal systems offer a win-win situation by providing energy cost savings, risk management, and environmental benefits to building owners, without the building owner having to raise the investment capital to install the solar thermal system. The ESCO methodology involves an energy audit, system design, performance guarantees, financing, and long-term maintenance, making it an attractive solution for driving sustainability in the built environment.

Objectives of Providing ESCO Services for Solar Thermal Systems:

  • Energy Cost Savings: One of the main objectives is to reduce energy costs for the building owner or occupants. Solar thermal systems capture solar energy to heat water or air, reducing reliance on traditional energy sources like natural gas, oil or electricity, resulting in lower utility bills for domestic hot water (DHW).
  • Guaranteed Energy Efficiency: ESCOs provide performance-based contracts, guaranteeing that the solar thermal system will generate a certain level of energy savings. This ensures that the client achieves measurable energy reductions.
  • Reduction in Carbon Footprint: Solar thermal systems contribute to lower greenhouse gas emissions by replacing or supplementing conventional energy sources with clean, renewable solar energy. The ESCO contract helps clients meet sustainability goals, such as reducing their carbon footprint and aligning with environmental regulations or certifications.
  • Risk Transfer: The objective is to transfer the technical and financial risk associated with the installation and performance of the solar thermal system to the ESCO. The client avoids upfront capital costs and operational risks since the ESCO manages these aspects.
  • Maintenance and Monitoring: Ensure long-term system performance by including regular maintenance, monitoring, and optimization services in the ESCO contract. The ESCO ensures that the solar thermal system operates efficiently throughout its lifespan, minimizing downtime and extending the system’s life.
  • Financial Flexibility: By offering financing options such as Energy Performance Contracts (EPCs), the ESCO can structure payments to be linked directly to the savings generated, allowing clients to install solar thermal systems without upfront capital expenditure.
  • Compliance with Renewable Energy Standards: Many regions require buildings to meet certain renewable energy or emissions standards. Providing ESCO services for solar thermal systems helps clients comply with these regulations without direct investment.

Methodology of Implementing an ESCO Contract for Solar Thermal Systems:

Preliminary Energy Audit and Feasibility Study:

Energy Audit: The ESCO conducts an in-depth energy audit of the building to assess current energy usage, heating demands, and the feasibility of installing a solar thermal system. This includes evaluating roof space, solar exposure, and potential integration with existing heating systems. 

Technical and Financial Feasibility Study: Assess the technical suitability and financial viability of the solar thermal project. This includes calculating the expected energy savings, payback period, and return on investment (ROI).

Proposal and Project Agreement:

Based on the audit, the ESCO presents a detailed proposal outlining the solar thermal system design, the projected energy savings, costs, timelines, and contract terms. 

Energy Performance Contract (EPC): The contract specifies how the ESCO will deliver energy savings, system installation, operation, maintenance, and financing. It also outlines the terms of guaranteed savings and how the ESCO will be compensated (usually from the savings generated by the system).

Financing Model: Several financing options can be included

Shared Savings Model: The ESCO finances the solar thermal system, and the client and ESCO share the energy cost savings. This minimizes the client’s upfront costs and operational risks.
 

 Guaranteed Savings Model: The ESCO guarantees a specific amount of energy savings, and the client finances the system. If the savings fall short, the ESCO compensates the client.

Third-Party Financing: The ESCO may secure third-party financing for the system, allowing the client to pay through the savings over time without making an upfront capital investment.

System Design and Engineering:

The ESCO is responsible for the design of the solar thermal system, ensuring it meets the client’s heating needs and building specifications. This includes selecting solar collectors, pipework systems, thermal storage, heat exchangers, pumps, and controls that maximize efficiency.

Installation and Commissioning:

The ESCO manages the installation process, ensuring the solar thermal system is properly installed, tested, and commissioned to deliver the expected energy output. The ESCO may hire subcontractors or work with in-house teams for installation.

Monitoring and Maintenance:

Performance Monitoring: The ESCO continuously monitors the system’s performance using real-time data analytics, ensuring the system operates efficiently and meets the guaranteed energy savings. Any performance shortfalls are addressed by the ESCO.
 

Routine Maintenance: The ESCO provides ongoing maintenance services to ensure the solar thermal system remains in optimal condition. This includes cleaning collectors, checking system pressure, and ensuring mechanical components function properly.

Measurement and Verification (M&V):

M&V Protocols: An essential part of the ESCO contract is a robust measurement and verification process to ensure that energy savings are real and measurable. This can follow established protocols such as the International Performance Measurement and Verification Protocol (IPMVP).  

Performance Reporting: The ESCO provides regular reports detailing the energy savings achieved, system performance, and any maintenance performed.

End of Contract and Asset Transfer:

At the end of the contract period, the ownership of the solar thermal system will be transferred to the client, as stated on the terms of the agreement. The ESCO may continue to provide maintenance and iniate other performance guarantees, of other Installation opportunities for saving energy, under a new contract.

Energy Service Company (ESCO) contracts for solar thermal systems installed on buildings, such as hotels in Portugal, can offer significant benefits and follow a structured process. These contracts are designed to promote energy efficiency, reduce operating costs, and enhance sustainability through renewable energy solutions like solar thermal systems.

Advantages of ESCO Contracts for All Parties Involved:

ESCO contracts for solar thermal systems offer a win-win situation to all Parties involved, by providing energy cost savings, risk management, and environmental benefits to building owners, while also creating business opportunities for ESCOs. The methodology involves an energy audit, system design, performance guarantees, financing, and long-term maintenance, making it an attractive solution for driving sustainability in the built environment.

Advantages for the Client (Building Owner/Occupant):

  • No Upfront Capital Costs: The ESCO often finances the solar thermal system, eliminating the need for upfront investment by the client. Instead, the system is paid for through the savings it generates.
  • Guaranteed Energy Savings: The client benefits from a performance guarantee, ensuring that energy savings are achieved. If the savings fall short, the ESCO absorbs the financial risk.
