The technology group Wärtsilä has commissioned its 6 MW/6 MWh energy management and storage system project for its customer ContourGlobal Bonaire on the Caribbean island of Bonaire. With Phase One complete, the island no longer has to curtail wind resources. It has nearly doubled renewable energy penetration, and prepared the system for additional capacity to accommodate peak demand during tourist season. ContourGlobal’s entire island grid is managed and operated by Greensmith GEMS advanced software platform.

The utility’s phased approach allows time for system operators to add new hybrid solutions and spread out costs, and leaves room for new technologies to come online. For Bonaire, Phase One involves GEMS managing an optimising dispatch and operation of existing generation assets. It also provides spinning reserve requirement with energy storage to reduce fuel consumption and emissions. Furthermore, Phase One involves unlocking curtailed wind energy and improved system reliability by providing frequency and voltage control. To optimise the system GEMS now factors in real-time asset performance, as well as load and renewable energy forecasts. With Phase One complete, GEMS can balance Bonaire’s resources and seamlessly optimise thermal, wind and energy storage assets.

During the commissioning tests, several load rejections were tested, including loss of wind, loss of engines and loss of demand, and in every circumstance GEMS instantaneously tracked and maintained the quality of the generation avoiding the load shedding of the grid. This is just one example of how this project will improve operations through automation while helping the island avoid blackouts, achieve greater efficiencies and use more wind power.

Commissioning of the project puts Bonaire on the path to achieving its 100% renewable target. This is the beginning of a longer-term plan to fully modernise the island’s system and add additional capacity and renewable energy generation to the grid. ContourGlobal Bonaire commissioned the project after years of seeking solutions to integrate more renewable power into the existing island grid.

The next phases for the Bonaire project will replace outdated thermal technology with five new engines and add more wind and solar to the generation mix. As the island grid increases in size, GEMS will enable further renewable penetration and lower the cost of energy. GEMS machine learning and AI capability will incorporate weather, electricity demand and other variables and data into its forecasting models. This data will inform the automated decisions managing ContourGlobal’s entire fleet.

Wärtsilä has been awarded an integrated 6 MW energy storage project contract for the Caribbean island of Bonaire. The engineering, procurement, and construction (EPC) hybrid energy project includes both the hardware, consisting of batteries and inverters, as well as GEMS, the energy management software from Greensmith Energy, a Wärtsilä company. The order with ContourGlobal Bonaire, a subsidiary of London based ContourGlobal, was booked in Q4, 2018.

The energy storage system will enable Bonaire, part of the Netherlands Antilles, to increase its use of renewable energy such as wind and solar. In order to integrate more renewable energy and its intermittent nature, the Wärtsilä energy storage solution will provide the grid stability and reliability required for the island. The energy storage solution will also prevent situations where generation from renewable sources would otherwise had to be curtailed.

The project will integrate multiple generation assets including all of the island’s existing power generation assets, energy storage, wind and solar. GEMS software will control the island grid of Bonaire, an island of 19,000 inhabitants. Work on the Wärtsilä EPC project has commenced, and final completion is expected in April 2019.

Greensmith’s GEMS software platform offers the widest range of energy storage applications for optimising energy storage, often integrated with a growing variety of renewable and thermal generation assets.

Capgemini’s World Energy Markets Observatory report 2017

Capgemini, has published the nineteenth edition of its annual study, which for the first time goes beyond Europe and becomes the World Energy Markets Observatory (WEMO) report, built in partnership with the I4CE, De Pardieu Brocas Maffei and Vaasa ETT teams. The study reveals that progress in the sector’s generation technologies has caused an acceleration in the Energy Transition, while related renewables growth continues to destabilize the wholesale electricity markets and key players. The study also highlights a profound change in customer energy usage, behaviors and expectations, with, for example, self-consumption, smart homes, smart buildings, smart plants, smart cities and the creation of communities to purchase or manage energy differently.

As a result, the financial situation of established Utilities remains challenging. The report encourages utilities to accelerate their transformation efforts and to leverage increasingly the power of digital transformation.

The three main findings of the 2017 edition of the World Energy Markets Observatory report are:
 
Rapid evolution of generation technologies makes the renewables penetration unstoppable, thanks to their competitiveness gains, and despite the end of feed-in tariffs in Europe

During the past 12 months, the costs of renewable energies have continued to fall: onshore wind and utility scale photovoltaic (PV) costs are becoming competitive in some countries, compared to traditional electricity generation resources (nuclear, coal, gas). A recent auction for solar PV generation plants recorded a lower cost in sunny Saudi Arabia, with only 17 $/MWh. Battery storage costs decreased also by about 20%. The ingredients now gathered favor Energy Transition with limited political intervention.

According to Colette Lewiner, Energy and Utilities senior advisor at Capgemini, “Efforts in R&D and industrialization are boosting renewable energy development, even when considering extra network investments linked to intermittence and energy generation distribution. Today, their intermittency coupled with the absence of pricing reforms, mean the impact of renewable energy on the wholesale markets prices threatens electricity supply and impacts negatively utilities’ finances.
 
Empowered smart energy consumers are pushing Utilities to deliver new energy services.

All customers (residential, tertiary or industrial) now expect from their suppliers’ offerings better management of their energy (examples include self-consumption, smart home, smart building, smart plant, electric mobility). With the participation of the customer in energy communities, the way energy is purchased or managed collectively is also now evolving.

For Perry Stoneman, Head of the Energy and Utilities sector at Capgemini, “We observe many Utilities creating new customer divisions that are focused on chasing the Holy Grail: the differentiating services valued by the customer, allowing the development of new revenue streams with better margins. With variations from one country to another, the vast majority of players are moving in that direction, but very few, for the moment, have found the appropriate recipe. Innovation capabilities and agility for a rapid and successful go to market are generally missing.
 
Established Utilities, heavily hit by Energy Transition and customers’ evolving expectations, have started large transformations. It’s now time to accelerate by leveraging Digital Transformation.

Most of the big players have launched transformation plans that they are executing with a particular attention. This is also the case in North-America, where the Utilities’ finances are less challenged than in Europe, thanks to a lower pace of Energy Transition and different market rules. In addition to simplifying their internal processes, these transformation plans generally focus on the downstream business (networks, green energy and customers’ energy services), designing and managing new operations and business models. Gains could also be sought in the generation side of the value chain. Digital technologies are evolving continuously to provide new solutions (for example Robotic Processes Automation, Artificial Intelligence, Internet of Things, or Blockchain were not available a couple of years ago). The value of managed data – Analytics – remains also largely unexploited.
 
The World Energy Markets Observatory is an annual publication by Capgemini that monitors the main indicators of the electricity and gas markets in Europe, North America, Australia and South-east Asia, and reports on the developments and transformations in these sectors. This 19th edition, which is drafted mainly from public data combined with Capgemini’s expertise in the energy sector, refers to data from 2016 and winter 2016/2017. Special expertise on regulation, climate challenges and customer behavior is given respectively by De Pardieu Brocas Maffei, the I4CE – Institute for Climate Economics – and VaasaETT research teams.

SediREC from Sedical is designed for the energy and volumetric management of water in heated swimming pools providing very high levels of energy efficiency. This system, able to manage one or several pools in the same sports centre all day long, has already been installed in different facilities, achieving excellent results that are even better than the forecasts made prior to installation. One such facility is the Altzate municipal sports centre in Lezo (Gipuzkoa), where the SediREC system has been in operation for nearly two years, achieving monthly savings on the energy bill of more than €2,000/month.

Inaugurated in 2001, the Altzate sports complex houses two swimming pools: the main pool (large) and a small pool which is used for aqua-gym, hydrotherapy and children’s swimming lessons. The total volume of both pools is 571 m3. Prior to the installation of the SediREC system in May 2013, management of the pools’ renovation water, essential to guarantee the required water quality, represented a cost of €3.76/m3, generating a monthly expenditure of €2,512. Table 1 provides an analysis of the operating situation of these swimming pools before installation of the SediREC system.

The custom of cleaning the filters for 5 minutes every 3 days for the large pool and 5 minutes every 2 days for the small pool, involved extracting a considerable volume of water from the filter with the associated energy loss being compensated for by means of boilers. Read more…

Following the sharp increases in the price of energy over the last six years and the increasingly widespread incorporation of installations that offer added value to the establishment but which increase its energy expenditure (spas, swimming pools, gymnasiums, etc.), the hotel sector today is aware of the significance of energy as part of its operating costs. Proof of this is that fact that a large proportion of hotels have undertaken, or are considering carrying out, some form of measure to improve energy efficiency.

However a very large number of establishments lack knowledge and information regarding the energy consumption generated, which prevents the development of energy efficiency improvement measures and reductions in consumption with the sufficient technical solvency and the possibility of measuring and verifying the sought-after savings.

It is very important that the hotel owner improves their knowledge in terms of when, how, where and how much energy is consumed by the facilities of each hotel, as in this way they will have access to very valuable information to aid the decisionmaking process on the improvement measures to be carried out, offering a real tool to subsequently verify their effectiveness.

Energy management is an organised energy consumption forecast and control procedure that aims to achieve maximum possible energy output without diminishing performance level (comfort, light level, etc.). Energy is power in time and in this second factor, usage management is where energy savings can be achieved in addition to reducing the environmental impact of municipal installations.

A thorough understanding of the energy-consuming installations of a municipality requires the input of an expert technical team to assess the current situation and evaluate proposals that have acceptable investment recovery periods, give the necessary guarantees and offer the best technology in each case.

A3e, the association of energy efficiency companies, of which Letter Ingenieros is a member, proposes three types of audit depending on the level of detail required: diagnostic, audit and ESCO audit. For a municipality that would like to enter into an Energy Services (ESCO) contract the latter is fundamental as this will contribute information to the specifications that is non-binding in the event of inventory errors or subsequent investments that might be omitted from the tender. This latter audit should include a standardised study of the installations in order to establish the non-savings services to be included in the contract, as well as the business plan, so that the ESCOs can assess the profitability of the project with all the information on the table.

The Siemens Building Technologies Division has won the 2015 European Energy Service Award (EESA) in the Projects category for its implementation of an Energy Performance Contracting (EPC) project in the Polish city of Sosnowiec. This project focused on the heating systems and energy management in 87 public schools and preschools in this industrial city in the Silesia region. All heating and lighting systems in the buildings were modernized from the ground up in a period of just ten months. In addition, the Advantage Navigator energy monitoring system was installed to remotely monitor overall energy consumption.

The system allows personnel to remotely control the room temperature in every classroom and set it to the desired target value. “In the past, classrooms were typically kept too hot, which made it difficult for students to concentrate. Thanks to the state-of-the-art heating system and continuous energy monitoring we are now able to provide a comfortable learning environment for students,” says Marek Tobiacelli of Siemens Poland.

At the same time, Siemens has guaranteed heating cost savings of approximately 31 percent, electricity savings for lighting of 21 percent and a reduction of CO2 emissions by 5,220 t/year compared to the initial situation. The measures are financed through an Energy Performance Contract with Siemens. This means that the city of Sosnowiec’s initial investments of approximately 4 million euros will be paid back through the guaranteed savings realized over the ten-year contract period; interim financing is provided by Siemens.

The impressive energy and cost savings for the city as well the positive impact on the environment are a big win in and of themselves. However, the results achieved also benefit students and teachers who are now able to learn and work in classrooms offering a comfortable temperature – and hence a healthier environment.

The European Energy Service Award (EESA) is part of the European Energy Service Initiative toward the EU 2020 Energy Saving Targets (EESI 2020). This initiative aims at fostering the use of Energy Performance Contracting in Europe. The EESA honors outstanding efforts and achievements in the field of energy services in Europe. This year’s award ceremony will be held in Brussels.
