SEALIFE – Power Regulators on main Aquarium System

Development Area: Operational equipment

Merlin Entertainments recognizes that its operations impact the environment and that effective management of this impact is essential to achieve a sustainable business. We are committed to regularly monitoring, auditing and reviewing our activities and identifying opportunities for sustainable environmental improvement, in line with our strategic business goals and in order to minimize the potentially harmful effects of such activity.


Taking into consideration the energy costs of SEA LIFE Porto since 2009 (opening year) and its associated carbon footprint, in 2014 we installed power regulators on the main tropical water system (the system that powers tropical water to our main tanks).

The power regulator function was to switch on and off the pumps depending on the reading levels of the water system (temperature, ozone levels, etc.). In this way, instead of the system being always on, we played with the optimal intervals of each parameter needed for the water to be perfect, so the system could decide when it would be best to be on/off and still maintain all the parameters within the right levels. Doing this, we could slightly fluctuate some parameter levels, without endangering the creatures that live in these waters.



The regulators were installed in late 2014, and the average cost to SEA LIFE Porto for the following years (2015, 16 and 17) was reduced by 55% in kWh spent.

Motivation for its development – Reduce carbon footprint; lower energy costs

Developed activities – Installation of power regulators

– Results (effective or expected and quantified and valued in euros) – 55% less kWh spend (2014 vs average spends of 2015/16/17)

– Lessons learned – With a simple item of equipment we were able to reduce our power consumption by more than half





This was one of the measures implemented locally to reduce our carbon footprint. SEA LIFE Porto continues to improve its environmental policy with sustainable measures to reduce our operational impact.


SEA LIFE Porto, as part of Merlin Entertainments, follows a strict environmental policy.


Specifically, we will:

  • Comply with all relevant legislation and where appropriate and practicable, exceed these requirements and apply best practice.
  • Promote a culture of environmental responsibility and awareness through the group sustainability team who will be responsible for implementing the policy with the support of regional and local sustainability contacts to ensure a consistent corporate operating standard.
  • Promote communication of our environment sustainability initiatives (water reduction, energy reduction, awareness campaign and recycling to guests, employees, contractors and suppliers).
  • Encourage business partners to carry out their activities in an environmentally responsible manner, and where appropriate, make this a condition for business relationship
  • Further develop our excellent standards on managing marine habitat and wildlife, applying best practice across the Group’s animal collections.
  • Management of impacts on biodiversity from our projects by carrying out environmental impact assessments.
  • Plan practical and cost-effective water, waste and energy conservation and pollution control measures through energy reduction, water management, effluent management, waste reduction, recycling and diversion from landfill in order to minimize environmental impacts associated with the Group’s operations.
  • Encourage regular investments in environmental initiatives such as low carbon and renewable technologies, energy efficiencies projects, improved water management and recycling facilities.
  • Measure, monitor and make public our annual carbon emission with set carbon reduction target of at least 2% year on year on our base year emission (2014) using revenue as the intensity metric. (A 2% annual reduction target will be set for water and wastefrom 2016 based on our 2015 data also using revenue as our intensity metric).
  • Work with stakeholders to minimize the impact of our products and services by incorporating carbon reduction initiatives in design of products and services as well as encourage innovative product development, supply chain management and end-of-life recycling.
  • Strive to continually improve our environmental performance and minimize the impact of our activities by periodically reviewing our environmental policy at Board level in light of our current and planned future activities to ensure our strategic business growth is sustainable.
