About
us

Gemweb is the result of more than 25 years of research and technological development in accounting and energy efficiency software, which automatically digitizes all information (regulatory, energy, water, environmental, etc.) available in the networks to build a database with updated, real, complete and reliable information.

During this time gemweb has been adapting to changes in the energy sector and to the needs of users to offer advanced solutions and better adapted tools.

Gemweb allows you to manage, analyze, predict, study and validate all the details in a cost-effective way to rationalize consumption [kWh], optimize costs [€] and reduce emissions [CO2].

Research, innovation and development

Our history, our future

1990s: A SW for energy accounting and efficiency is born

In the middle of the decade, as a university project of the ETSEIB - UPC, the CEM program (acronym for Municipal Energy Accounting) is implemented in FORTRAN for MS-DOS.

1997: WinCEM start-up

At the end of 1997 the Generalitat de Catalunya through the ICAEN (Institut Català de l'Energia) publishes the first version of WinCEM, distributed on 3.5" diskettes, to be installed on local Windows computers. Start of a contract with the current managers of gemweb that will promote, in community, the development and maintenance of the first energy accounting application for the national market..

Years 2000 and 2001: Y2K effect and €/Pta

WinCEM is adapted to the Y2K and versions are implemented with dual currency processing for €/Peseta, which also included the management of telecommunication invoices and which will later be discontinued.

2004: Consolidation

Version after version and thanks to the distribution efforts of ICAEN, WinCEM is consolidated in the small and medium municipalities of Catalonia as the only tool, economic, basic and useful for the management of energy and water data through the information extracted from the billing, enabling the generation of reports on the energy needs of public entities and their impact on the environment.

2007: GPL License

A decade later WinCEM is once again a software forerunneras the first energy accounting application to be published on the servers of La Farga as an open source license, at the proposal of our development team and with the support of ICAEN. WinCEM 6, the latest version, is born.

2009: End of WinCEM

December 31, 2009 marks the date for the discontinuation of WinCEM maintenance, a tool promoted and sponsored by the administration for 12 years.

2010: The gemweb community is born

On January 15, 2010 the current team, encouraged by the users and with a lot of entrepreneurial enthusiasm, based on a copy of the released open source code of WinCEM 6 and once again unprecedentedly, publishes the first GPL (General Public Licence - Free Software) version of a tool (General Public Licence - Free Software) version of an accounting and energy efficiency tool in hosting as SaaS (Software as a Service) under the name gemweb2010, an acronym for Global Energy Management on the web, year 2010.

2011: gemweb2.0

After a successful presentation in Barcelona attended by more than 100 industry specialists, on April 1, 2011 a completely revamped version, gemweb2.0, an acronym for a second version in a web2.0 environment, went into production. It was was once again the first tool to be updated to the new liberalized HV and LV markets, capable of managing, calculating and validating any billing, even with indexed tariffs.

2013: Open Energy is born

On April 17, a new company was incorporated to manage the development, maintenance and marketing of the gemweb software, which is constantly evolving and growing.

2016: gemweb in Madrid

Open Energy expands with a new headquarters in Madrid to support the dissemination of energy accounting and its operations and marketing services throughout the country.

2018: New markets and new needs

Progressive growth of the internal sales, development and operations teams, as well as the adaptation of the platform to new market needs.

2020: SARS-CoV-2 (COVID-19)

Thanks to the resilience of any team, Open Energy reorganizes itself to face its operational continuity with the maximum possible normality in a situation of lock-down pandemic, initially by incorporating teleworking at all levels and, subsequently, by adding the necessary and recommended health protection solutions in its offices.

2021: Tariff change - CMVP

On June 1st Gemweb has already incorporated the new tariff system of the new environment in the national electricity and gas market, adding it to its management modules.

Our CEO obtains the CMVP (Certified Measurement & Verification Professional®) certification as a qualification recognized by the Association of Energy Engineers in the field of measurement and verification.

2022: Datadis

Gemweb incorporates its connection with Datadis, starts downloading thousands of load curves and surpasses the 100,000 management (energy and water) service level.

2023: ENS

Gemweb obtains the ENS (National Security Scheme) seal, as a model of good practice (OECD, better policies for better lives), to create the necessary conditions for the promotion, continuous management, prevention, detection, correction and homogeneous treatment of security.

2024: Renewed image

Gemweb creates its new visibility and dissemination image to be implemented on all its platforms. New website published in April 2024.

2030: 17 Sustainable Development Goals

The demand for environmental solutions and the rapid evolution of markets pose new challenges, which our team is facing with renewed energy, responsibility and a lot of commitment and enthusiasm, to actively contribute to the achievement of the Sustainable Development Goals (SDGs) of the 2030 Agenda.

The Gemweb community

Gemweb has become a reflection of the experience and knowledge of users, professionals and colleagues who have anonymously participated in its development for more than 25 years.

Thus, we currently have a complex tool and its large structured database, to offer the best analysis and solutions in each particular case. 

Gemweb has structured the training and communication of its entire community in energy accounting and efficiency for national markets and has positioned itself as an essential basis for managing energy and water needs, that is, as the first step in building energy saving and efficiency projects, which are as necessary as they are urgent.

I want to be part of

Our Mission

We want to promote greater rationalization of energy needs and water consumption.

by using more technology in the acquisition, management and use of energy data, already available without the need for investment, as complete and reliable as possible, in order to optimize resources, increase local renewable electricity generation, save costs and reduce demand requirements and GEH's footprint, improving comfort and quality in working conditions.

Our vision

We provide everyone with easy and cost-effective access to the management and analysis of all their energy data [€, kWh and CO2]. 

To be an inspirationfor everyone who knows us, in raising awareness of the social and environmental needs of our society, based on an open and collaborative software platform, sharing experience and knowledge and promoting communication in the sector of an entire community.

To be the support and documentary support to initiate any energy efficiency and sustainability project and thus be able to promote the most appropriate decisions and conclusions and monitor the impact of the actions carried out.

To participate in the promotion of the most advancedtechnologies available, in areas such as BigData, AI, Machine Learning, digitization and automation available, in aspects such as BigData, AI, Machine Learning, digitalization and automation, which facilitate the acquisition, study, exploitation and visualization of energy information.

Our values

The DNA of every gemworker is based on sharing, respecting, promoting and fostering, internally and externally, a healthy working environment with enthusiasm for their project.
