About

Energy projects with a purpose.

My career in renewable energy combines business development, project delivery and international collaboration. I co-founded dpSun, a UK clean-energy company focused on energy access and innovation, and KRD Renewables, which advises on renewable energy and energy storage projects.

Through dpSun, I have worked on UK-supported innovation programmes in Africa, the Pacific and Ukraine. Through KRD, I work with developers, investors and lenders assessing projects, particularly in Poland and Central and Eastern Europe. My earlier career in solar manufacturing gave me a grounding in procurement, cost control and supply chains.

I also volunteer as a mentor in the Help to Grow: Management programme and serve on the Member Council of the Organisation for Responsible Businesses.

My work

Two companies. A shared focus on clean energy.

From the early assessment of an investment to the practical work of deploying a new energy system, my teams bring different disciplines together.

SPARC: from feasibility to an operating mini-grid.

As project manager for the first phase and through dpSun’s lead role in the implementation phase, I worked with partners on SPARC, a solar-powered mini-grid project supporting households and agricultural activity in Edondon, Nigeria.

The project documentation records an operational mini-grid, a cassava processing facility and a completed dpSun workstream establishing an entrepreneurship hub and supporting productive uses of energy.

Figures below come from the SPARC Phase 2 project documentation described in the material provided. They refer to the consortium project, rather than outcomes attributable to one person alone.

Selected experience

A wider view of the energy transition.

Storage at scale

At KRD Renewables, I have worked on technical due diligence for a 5.2 GWh battery storage portfolio and advisory across solar PV, wind and battery projects in Poland and the wider CEE region.

International innovation

dpSun’s project portfolio includes rural electrification in Botswana, grid stabilisation in Samoa and clean-energy projects in Ukraine spanning storage, heating and agricultural energy. I have also taken part in Innovate UK international brokerage missions in Africa and Asia.

Education & foundations

I hold an MBA from Universidade da Coruña and a business degree from Universidad de León. I participated in the Cambridge Judge Business School Ignite Programme in 2020 and 2022. Earlier, I worked in finance and procurement at Spanish solar PV manufacturer Pevafersa.

Beyond the projects

Sharing experience and building connections.

UK business mentoring

Since at least 2025, I have volunteered as a mentor through Help to Grow: Management, supporting business leaders through individual mentoring engagements.

Women in energy

I mentored through the GWNET Energising Women to Advance the Energy Transition programme from May 2023 to June 2024.

Responsible business

As a Member Council participant at the Organisation for Responsible Businesses, I contribute time to discussions and initiatives supporting responsible business practice.

International collaboration

My work has included Innovate UK-supported brokerage activity and projects in countries across Africa, Asia and the Pacific, as well as clean-energy collaboration in Ukraine.
