Millstream Eco-Retreat Stand Alone Power System

OVERVIEW:

NEN Consulting was tasked with conducting an extensive investigation into the configuration and performance of a stand-alone power system, designed to power a brand new eco-retreat. The primary objective was to establish an environmentally friendly, off-grid 5 star camping site that would boast an impressive range of on-site facilities, including luxurious kitchens, spacious tents, exquisite dining halls, as well as staff and guest housing.

UTILITIES CHALLENGE:

NEN Consulting was tasked with conducting an extensive investigation into the configuration and performance of a stand-alone power system, designed to power a brand new eco-retreat. The primary objective was to establish an environmentally friendly, off-grid 5 star camping site that would boast an impressive range of on-site facilities, including luxurious kitchens, spacious tents, exquisite dining halls, as well as staff and guest housing.

SEAMLESS SOLUTION:

NEN Consulting rose to the occasion by conducting a comprehensive analysis of potential equipment and related loads. This was a crucial step in delivering a high-level design that would meet the resort’s unique energy needs.

By closely studying the room descriptions and analysing the power usage of other similar eco-retreats, NEN was able to create a realistic load profile of the entire resort. This ensured that the off-grid power system could handle the expected power usage without relying too heavily on generators, which would have been less than ideal. NEN Consulting leveraged its expertise and advanced analysis skills to tackle the unique power challenges faced on this project.

By creating a preliminary list of electrical equipment and corresponding load profiles, they conducted a comprehensive analysis of the available solar resources in the area. Then, the team used in-house simulation software to examine hourly demand and the required mix of generation and storage to service it.

This software allowed NEN to balance multiple on-site demands, including kitchens, art centres, and residences, with on-site generation from solar and diesel generators. The simulation model considered the optimal balance of solar array, battery, and generator sizes while factoring in the cost of fuel and the price of increasing solar generation and battery implementation. The final solution focused on reducing generator usage while providing for an economical deployment of renewable energy resources.

The result was a preliminary design for a stand-alone power system that could operate entirely off-grid, requiring only 63 hours of diesel- generator use per year on average.

NEN Consulting’s innovative approach and dedication to finding an optimum solution led to an optimised outcome for this client. 

MULTIDISCIPLINARY APPROACH:

We combined market research to develop key features and requirements, then through engineering and iterative process analyses solutions to provide the optimal solution maximising features while focusing on cost to help the client develop a business case and specification for further tender. 

This included the following:

  • Provided multiple power system options for off-grid power business case.
  • Integrated engineering design and economic modelling to provide business case and preliminary design for a system capable of running off-site grid with minimal generator intervention
  • Created engineering specification and functional drawings detailing system requirements to facilitate tender.
  • Provided solar yield estimates based on location, building designs, and planned use areas
  • Energy usage, load analysis modelling
  • Executive report to support feasibility and business case.
