Municipal Energy Resilience Project

Location: South Africa, Northern Cape, Springbok
Project start and end dates: January 2021 - November 2021

Project Description

The objective of this project is to provide project development support and capacity building to the municipalities in the Western Cape province in South Africa, with the view to implement renewable energy projects. These projects are intended for implementation by IPPs and will provide energy resilience against power quality and tariffs, for businesses, households, and other energy users.

Services Delivered

The development of business cases for multiple renewable energy projects throughout the province. Identification of pioneering projects in candidate municipalities and the development of a project roadmap for the implementation of projects.
Royal HaskoningDHV formed part of a consortium of legal, financial, and technical consultants and provided the technical inputs in this assignment.

Transaction Advisory Services to Establish solar based electricity and alternative generation system

Location: TubatseFerrochrome Plant, Lydenburg/Steelpoort, South Africa
Project start and end dates: Phase 1: January 2021 – Ongoing, Phase 2: January 2021 -Ongoing

Project Description

In Phase I of the project, Royal HaskoningDHV, in collaboration with Webber Wentzel and Cresco were appointed as transaction advisors to investigate the Viability of this generation solution from a Legal, financial, and technical point of view. Phase 2 is to provide Transactional Advisory Services in investigating renewable and alternative power generation for the TubatseFerrochrome plant.

Services Delivered

The advisory services reviewed solutions such as on-site solar generation, power wheeling, co-generation, and gas-to-liquid conversion of the smelter off gas. Prospective sites for solar generation were evaluated from a technical and environmental point of view. Financial calculations such as IFRS and tariff perspectives were calculated for the various technical solutions. The IPP legal and contractual matters were investigated, and advice was provided on the drafting of a Power Purchase Agreement. A framework for an IPP RFP was drafted and a strategy for the implementation of the alternative power solution was compiled. Phase II of the project includes the studies and investigations required for the preparation of an RFP document for IPP companies to submit proposals as well the adjudication thereof. A concept design for the 100MW on-site solution was compiled and the full Environmental Impact Assessment process was undertaken, including application to the Authorities.

Butterfly Blue Renewable Energy Investigation

Location: Blue Downs, Cape Town, South Africa
Project start and end dates: January 2021 - January 2022

Project Description

A Renewable Energy investigation for the potential off-grid electrical supply to the proposed Butterfly Blue residential development. The development is situated in Blue Downs, Cape Town.

Services Delivered

After a load estimation was done, the different supply alternatives and technologies were investigated.
A comparison was done between Eskom (local supply authority) and a hybrid off-grid solution consisting of Solar PV, Battery Energy Storage and Diesel Generation.
Different development scenarios were evaluated in terms of technical and financial feasibility by comparing the Levelized Cost of Energy (LCOE) of each technology.
