A new energy future for estonia’s islands: EISEA leads the way

Last summer, the Estonian Islands Energy Agency (EISEA) was established to drive the transition to cleaner, more sustainable, and cost-effective energy in Estonia’s offshore communities. By supporting local authorities, businesses, and residents, EISEA fosters smart energy solutions that not only reduce carbon emissions but also strengthen island economies.

A Growing Force for Estonian Islands’ Transition

Founded by the municipalities of Saaremaa, Hiiumaa, Muhu, Vormsi, and Kihnu—along with local business associations, the Saare Development Centre, and Tallinn University of Technology—EISEA expanded in autumn 2024 to welcome the island of Ruhnu. As Estonia’s second regional energy agency after Tartu Regional Energy Agency (TREA), it is uniquely positioned to tackle challenges like low population density, weaker grid infrastructure, and untapped renewable energy potential.

Tailored Support for Local Needs

EISEA works closely with municipalities, businesses, and communities to drive energy improvements. It supports public authorities in renovating buildings, modernising district heating, decarbonising transport, and attracting investment. Businesses benefit from resource efficiency planning, fleet emission reduction strategies, and renewable energy projects, while communities receive guidance on forming energy cooperatives and improving apartment building energy efficiency. Education is also a key focus, with a training programme in development for primary school students.

First Successes: A Smarter, Warmer School in Kihnu

One of EISEA’s early achievements is the renovation of Kihnu’s schoolhouse, a 1972 building suffering from poor insulation and inefficient heating. Ground heating struggles to maintain indoor temperatures, forcing the school to rely on electric water heating. To address this, EISEA coordinated an energy-efficient design procurement, engaging specialists in a one-stop-shop approach. The renovation, set to begin in summer 2025, will significantly reduce the school’s energy consumption and carbon footprint while ensuring a more comfortable learning environment.

A Resilient Energy Future for Estonia’s Islands

“The energy challenges faced by our islands are similar, but the opportunities vary,” said Sulev Alajõe, head of EISEA. “We help stakeholders navigate these limitations, find the right technical solutions, and secure funding to bring projects to life.”

By prioritising local energy production and self-sufficiency, EISEA is paving the way for a more resilient future for Estonia’s islands. Its work is made possible through funding from the European Union’s LIFE programme, contributions from its founders, and revenue from advisory services.
