Executive summary

• Solwatt is a comprehensive programme designed by Solvay to implement an energy management system on large energy-intensive industrial sites.

• Solwatt complies with the EN16247-1&3 norm and most of the ISO50001:2011 norm.

• The review phase follows two streams: - The technical stream, aiming at documenting in an action plan a minimum of 10% savings

through a series of short payback incremental improvements. - The behavioural and management stream, aiming at fostering a lasting culture of energy

management and savings on the site, with a detailed structure of KPIs and KAIs.

• The implementation phase is run as follows: - KPIs and KAIs are put in place by the site. - Improvements requiring no capex (« quick wins ») are put in place by the site. - Improvements requiring capex (« investments ») are put in place jointly with Solvay, who

provides the necessary capital through an operating lease. Savings are then shared between the site and Solvay over a period of five years for each asset.

• The total programme takes five to eight years to be completed, and during that time savings are typically shared 70% for the site and 30% for Solvay.

Key activities:

Final products:

• Diagnostic: identify losses and improvement areas • Idea generation and prioritization: run brainstorming sessions • Idea evaluation: create individual measure cards • Jointly build the new KPIs structure related to energy and propose their integration in the existing structure

• Master plan: define options to meet potential challenges of the current energy system of the plant • Short term implementation actions plan (technical + energy management) with associated financial consequences • KPIs-KAIs structures

Success relies on the involvement of the site

Objective: reduce energy bill by 10% or more

1 Create transparency

by delivering an objective diagnosis of

the situation to identify energy losses to

focus on

2 Foster creativity of

stakeholders at all levels of the plant and beyond by involving them all in

brainstorming sessions to generate many ideas

to save energy

3 Follow a structured

progressive evaluation process to filter out ideas

based on feasibility and payback and build an action

plan for the plant

Confidential

From idea to asset

11

Ideas are generated through brainstorming sessions. The most promising are kept as opportunities

Opportunities are screened through an opportunity matrix and those retained are validated.

After detailed study, opportunities become actions without capex or actions with capex. Actions are validated and sequenced in an action plan.

Required capex is provided by Solvay. Once carried out, an investment becomes an asset.

The profit sharing principle in an energy performance contract

• Capex is provided by Solvay.

• Implementation is jointly managed by the site and Solvay.

• Profit-sharing is based on calculated savings and paid quarterly.

• Asset operation and maintenance is delegated to the site against a fee.
