Stop letting grid constraints dictate your energy future.

Engineering a resilient, modern grid. We partner with network operators and utility providers to manage the evolution of the infrastructure, integrating demand-side flexibility and grid-scale assets for long-term reliability through Energy Networks & Infrastructure 

Turn grid volatility into a competitive advantage.

Energy networks are under unprecedented pressure. For network operators, utilities, and large-scale industrial users, the transition to a decentralised grid is an immediate operational challenge. If your site or network isn't optimised for grid-scale asset integration, you are exposed to supply risks and rising connection costs. At DETA, our specialised energy network engineers help you navigate this complexity. We don't just design systems; we ensure they are resilient, compliant, and ready for the future of utility-scale electrification. By bridging the gap between existing industrial energy infrastructure and new technology, we help you manage the energy transition without compromising on reliability.

Our Infrastructure Engineering Services

Grid Strategy & Feasibility (Microgrids & DES)

Microgrid design and engineering for businesses wanting energy independence or facing high grid-connection costs. We assess the technical and financial viability of "islanding" or augmenting your current supply.



  • Feasibility studies for on-site renewable generation and BESS integration.
  • Cost-benefit analysis of grid-firming vs. network upgrades.
  • Compliance and regulatory guidance for embedded networks.
