Charles KELLER – Responsible electricity services PALEXPO

A redesigned power distribution that meets the expectations of our customers and improves the quality and the working environment of our teams.
 

A PALEXPO, the first thoughts on the renovation of the electricity distribution network of exhibitors dedicated to the Palexpo date from the 2000s.

We then realized that our electrical distribution infrastructure, dating from the origin of Palexpo, that is to say 35 years ago, would not be to horizon 15 years, able to meet the requirements and needs of our customers.

The quality and size of events and stands that we are now entitled to host significantly increased and we absolutely had to accompany this trend and therefore adapt our distribution networks to the growing needs of our clients and working conditions of our teams.

Smart Connections

A smart control and counting device integrated into the building infrastructure: an option that has quickly become a must!
 
Palexpo SA charges electricity based on the precise consumption of exhibitors.
Graduate of an engineering school, I had a good vision on the issues of automation in our business. Integrating smart device developed by CUBE infrastructure offered, outside the functions of controling and metering, two other advantages: We no longer had to assemble and disassemble the counters for each exhibitor and for each event, a time saver.

The stands of the exhibitors were no longer encumbered by electrical boxes from the 70, far from the aesthetics and design of existing stands.
So we programmed upstream the complete renovation of each Hall, from the transformer 000/400 volts and 18 to the smaller plug of soil type A phase on October 15, through transformer stations, divisional cabinets intermediate and the floor doors.

A Win-Win Partnership

PALEXPO and CUBE is a win-win partnership that has allowed us to co-build solutions, develop our business and open new business opportunities!

A key issue of the renovation project and my own project manager approach was clearly the optimization of our business. This desire, shared with the CUBE teams, formerly themselves in charge of electricity distribution on exposure sites, has enabled us to co-build the project by incorporating the feed-back of my colleagues on their working methods, waste of time processes and the arduous nature of certain gestures or actions.
 
Result: The engineering and embedded technology in the CUBE terminals has been redesigned, integrated directly in the infrastructure in order to meet our very specific needs and our own business model.

Increased Skills

Our credo: not do as little as possible but do your best.

The CUBE systems meet all our expectations: we now have reliable and traceable records, translated into billable positions and therefore net profit for each operation.

We also moved the labor on new services offered by Palexpo SA. Before, our teams were only supports power supplies, while today the same teams provide benefits wiring full power equipement to the stands.
We can manage the complete implementation, from the general supply and up to the last bucket, including the installation of lighting systems, truss bridges and all electric delivery schedule.

Today, our six electricians have enhanced their image in all teams that are at work in Palexpo: we have become a competent service, which progresses and constantly innovating and federates team that is up to 40 electricians on large events.

ROI beyond our expectations

A sure bet: the ROI is to go beyond our expectations

One of our requirements, set out at the beginning of our collaboration and the installation of CUBE systems, specifically related to the timestamped metering of consumption. On some shows, a part of the electric consumption is billed on a package rate, based on a specific regulation on the time spans of powering the lighting equipments.

Following the Palexpo load curves, we noticed abnormal consumption. With CUBE systems, metering functions, timestamp and accurate memory consumption now allow us to know who used what, in a predefined time space for each event. So we can quantify the energy consumed outside the package and charge it.

This essential asset of the CUBE system allowed us to sensitize our internal CFO to have the budgets for investments not only our teams have improved their performance and efficiency in the implementation of the facilities but we now have a traceability precise to invoice services carried out trade agreements with exhibitors.

Furthermore, we have defined a new business model for the distribution of small modular stands, necessarily fed individually. The control of the power distribution between 1-10kW upstream, infrastructure and distribution terminals KEOPS allowed us to increase our revenues through automated tracking of consumption of each branch.

Prospects Horizon 2020

Future prospects in 2020 for PALEXPO: neutral events in energy consumption!

The ambition of Palexpo in 2020: a zero energy consumption venue - therefore we will have to produce at minimum as much energy as we consume.

This goal is, in the eyes of the general management of Palexpo SA and its board of directors, a structuring marketing challenge. It is actively supported by the institutions at local, cantonal and federal.
How to succeed in this challenge? The understanding the net consumption of exhibitors makes it possible to isolate the buildings consumption and to improve concretely and continuously the energy efficiency of our infrastructure.

Today, the rooftops of our buildings are already equipped with a solar power plant of 4GW, the production covers about 35% of our yearly consumption.
Now, to achieve our goals, exhibitors consumption has also to decrease. With our counting system, each exhibitor is now aware of its energy consumption which represents a clearly identified and billed load.
On our recurring exhibitions, we have seen substantial declines in "unnecessary" consumptions (often at night), charged in addition to the package rate. Exhibitors have simply sought to make savings in the next edition of the event.

The next step will be, no doubt, the establishment of an information system in real time during the event, or as projection before the event, so that the exhibitors will become actors of their power consumption, adjusted to their real needs...
