Achieving an ambitious sustainability goals

THE COMPANY

Eli Lilly,
a leader in the pharmaceutical industry

Logo Eli Lilly

Eli Lilly, a global leader in pharmaceutical innovation, has been transforming lives for nearly 150 years ago.  Founded with the principle of continuous improvement-Take what you find here and make it better and better”the company remains dedicated to advancing healthcare worldwide.

With operations in over 125 countries, Eli Lilly continues to develop life-saving medicines.  For more than 40 years, its Irish facilities have played a cricitalcritical role in supporting global innovation. 

Sustainability is central to Eli Lilly’s mission. To reduce its carbon footprint, the Irish unit partnered with Greenvolt Next Ireland (formally Enerpower) to design and execute a groundbreaking solar energy project, financing it via a 20-year Power Purchase Agreement (PPA). This collaboration not only resulted in a zero upfront investment for Lilly but also accelerated progress towards meeting its ambitious environmental targets, including a 26% reduction in greenhouse gas emissions by 2023.  

Eli Lilly has ambitious environmental goals, and the Irish unit chose Greenvolt Next Ireland, former Enerpower powered by Greenvolt, as a partner to develop, finance and execute the renewable energy project.

THE PROJECT

A Ground Mounted solar photovoltaic system

The ground-mounted photovoltaic system was built in 2 phases, featuring 21,552 solar panels with a combined capacity of 9.6 MWp. Financed through a 20 year-term Power Purchase Agreement (PPA), the installation accounts for 20% of the site’s annual energy consumption, avoiding approximately 2,435 tons of CO2 emissions per year.

THE CHALLENGE

Overcoming Covid
restrictions and
land limitations

The first phase of the project was developed during the COVID pandemic, which presented significant challenges due to associated restrictions and disruptions. Nevertheless, the project was remarkably completed in just over a year, including permitting and construction. In addition to Covid related restrictions, the project faced a lack of suitable land for expansion. To address this, Eli Lilly adopted a creative solution: leasing a neighbor farmer’s property to add another 4 hectares of behind-the-meter solar capacity. The project also encountered some technical challenges, such as integrating two different types of inverters in phases one and two, which forced the team to install a bespoke communication system to overcome it.   

SOLUTIONS

A tailored solutions that meets Eli Lilly needs

Technical Solutions

The ground-mounted photovoltaic system was built in 2 phases, featuring 21,552 solar panels and 38 inverters with a combined capacity of 9.6 MWp.
Phase 1 involved installing panels on-site.
Phase 2 expanded operations to the leased farmland.

Financial Solutions

Greenvolt Next Ireland, financed, constructed and maintains the project through a 20-year PPA. This model required zero investment from Eli Lilly, allowing the pharmaceutical company to achieve significant energy savings while reducing operational costs.

Operations and Maintenance (O&M)

To maintain maximum efficiency, Greenvolt Next Ireland employed a monitoring system to track energy production, enabling proactive maintenance to ensure optimal performance.

Specific O&M practices that are being implemented to guarantee reliability and efficiency include: 

  • Monitoring the performance of the system
  • Management of vegetation control
  • Panel cleaning
  • Thermography imaging for panel damage
  • Replacement of damaged parts
  • Identification of opportunities for system improvement

THE RESULTS

Delivering on ESG goals
and reducing carbon footprint

The solar plant has already produced 5.6MWh of green electricity reducing significantly the company’s dependence on traditional energy sources. This achievement aligns with Eli Lilly’s environmental, social and governance (ESG) goals, driving a meaningful reduction in its carbon footprint while reinforcing its economic competitiveness.

The fact that 12 hectares of land are the equivalent of almost 2000 hectares in terms of forest trees, in terms of carbon sequestration, was something that was also surprising to the community...”

Greenvolt Next Ireland partnership with Eli Lilly stands as a successful example of sustainable business practices but also as an illustration for future companies in the pharmaceutical sector of renewable energy adoption.

We bring energy to companies so that projects like these can be born
