Consulting Sustainable Energy Solutions

About Me

My name is Steen Kramer Jensen - I'm an engineer - and in 2016, I founded a startup (Peoples Portable Power) dedicated to developing IoT solutions for battery monitoring, "Pay-As-You-Go" and off-grid energy systems. Our focus was to create affordable, scalable solutions to improve energy access in remote areas, primarily in Kenya and Tanzania. Over six years, I led projects that provided sustainable power to communities and businesses, navigating the complex landscape of energy infrastructure in emerging markets.

Despite the challenges posed by the COVID-19 pandemic, which ultimately led to the closure of the company in 2022 (You can read the complete story here), the experience gave me invaluable insights into the intersection of technology and energy. Today, I leverage that experience to help startups turn their ideas into real-world solutions, providing expertise in IoT development, battery systems, and off-grid installations.

Bringing Ideas to Life with Practical IoT and Energy Experience

I offer part-time consulting services to startups working in IoT, battery monitoring and off-grid solar energy.

With hands-on experience developing and deploying systems in challenging environments, I provide guidance across the entire product lifecycle – from prototyping and testing to deployment and scaling.

Whether you’re refining an IoT device, designing a battery management system, or planning an off-grid energy project, I can help bridge the gap between concept and execution. My goal is to help startups overcome technical hurdles, avoid common pitfalls, and build resilient, impactful solutions.

Key Areas of Expertise

• Developing MVP prototypes with support from the Danish InnoBooster Scheme and validating them with end-users in Kenya and Tanzania.
• Establishing partnerships with global and local organizations such as Access2Innovation, GOGLA, and various micro-grid operators.
• Successfully integrating IoT technology for remote monitoring, payment integration, and usage analytics to enhance customer experience and operational efficiency.

Through hands-on experience, I gained insights that I now leverage to help other businesses succeed:

• Strategic Planning for Emerging Market Projects
• Tailoring solutions based on customer feedback and socio-economic conditions.
• Managing prototyping, production, logistics, and partnerships for cost-effective scaling.
• Implementing pay-as-you-go and monitoring systems and integrating renewable solutions into communities.
