Long-life power platforms for IoT applications

CNet is participating in the LoLiPoP-IoT project which is aiming to improve the battery lifetime and energy harvesting of wireless sensors that are retrofitted in IoT applications for monitoring purposes.

Consisting of 40 European partners, the project is creating an ecosystem of developers, integrators and users to develop power platforms which consider power/battery life, ease of installation and maintenance. Focus is on three main application areas: Industry, smart mobility and energy efficient buildings with use cases for asset monitoring & tracking, condition monitoring for predictive maintenance as well as environmental monitoring. The development of platforms enables reuse across multiple applications and projects.

CNet leads the specification and requirement work for the 10+ use cases, contributing to the development of use cases for district heating and smart buildings.

Apart from reducing the power consumption of sensors, the project will also demonstrate cost reductions, optimised asset management and improved comfort levels for building occupants.

CheckWatt expands with wind power

CheckWatt has acquired SM Teknik, a technology company specialising in connecting and controlling wind power stations. After this deal CheckWatt is now monitoring 662 wind power stations with an aggregated installed power of 956 MWatt. These power stations will now be possible to connect to the rapidly growing grid flexibility market in Sweden through CheckWatts virtual power plant Currently.

This makes CheckWatt the largest technology- and supplier-independent player in operation monitoring and aggregation of flexible energy resources on the Swedish electricity market.

Currently activated when nuclear power plant suddenly shuts down

CheckWatts virtual power plant Currently was activated last week when a finnish nuclear power plant was suddenly stopped. This is the biggest flexibility activation so far for Currently. Using Currently the grid operator stabilises the grid when the frequency suddenly changes.

Checkwatt provides energy management system for grid battery

CNets subsidiary Checkwatt provides the energy management system (EMS) for a 1MWh battery storage in Varberg. The system handles communication and control of the battery storage on site. This Container sized unit is the first step of a larger battery warehouse that is planned to be operational by 2023. CheckWatt’s cooperation partner Solkompaniet delivers and installs the main battery. A platform from Ntricity handles trades with Svenska Kraftnät.

Varberg Energi wants to develop and offer new services to customers. The battery warehouse is an investment to complement the existing energy system to strengthen the power balance and grid stability in general and to make the energy system more flexible and sustainable.

CNet joins smart city lighthouse project

CNet has joined the European project RESPONSE which aims to establish a strategic vision for Smart Cities Energy Transition: Climate-neutral cities by 2050.

The project aims to make energy sustainability reality by solving the energy trilemma (security, equity/affordability, environmental sustainability) at building, block and district levels in smart cities. The project builds upon intelligent integrated and interconnected energy systems coupled with demand-oriented city infrastructures, governance models and services that foster energy sustainability.

RESPONSE supports the lighthouse cities of Dijon (FR) and Turku (FI) and their Fellow cities Brussels (BE), Zaragoza (ES), Botosani (RO), Ptolemaida (GR), Gabrovo (BU) and Severodonetsk (UA). RESPONSE is led by the European Institute for Energy Research (EIFER) Germany, technically supported by Centre for Research and Technology Hellas, CERTH, Greece, and comprises of 53 partners in total.

CNet has been invited join for implementing our Bike As a Sensor platform in the city of Dijon.

CheckWatt extends business to Africa

African countries face the need to meet a fast-growing energy demand but its nations can pick from a portfolio rich in renewable energy sources, including water, sun and wind, among others. Building on experience gathered around the globe Africa can design it’s energy sector for the future.

Half of the continent has solar radiation intensities of more than 7000 kWh/m2/day, the perfect premise for utilizing solar power. Renewable energy sources offer additionally more independence from fossil material, improved resilience and sustainability.

CheckWatt, one of CNets subsidiaries, offers configurable energy related solutions for different needs. In the last year CheckWatt has extended their business to Europe. The companies expertise and experience is leading in the Swedish market and internationally competitive. CheckWatt is proud to announce that they have entered their first contract in Kenya, which entails the deployment of a new solar energy installation in Kenya. Dan-Eric Archer, VD of the company, supervised delivery and installation of solar meters, real-time measuring at the connection point to the electrical grid, Plug and play production demo on screen himself:

CheckWatt adds energy storage services

CNets spin-off company CheckWatt is expanding services with solutions to store energy and manage usage intelligently.

The fast growing market of private solar installations and electrical vehicles are followed by extended needs regarding the electrical infrastructure but also offer new possibilities for utilization. In 2019, the market for electric grid ancillary services was approximately 1.5 billion SEK. Svenska Kraftnät forecasts that it will double twice by 2023, driven by the growing share of intermittent power production (solar and wind) within the electricity mix and an increased integration within Europe (regulating power as an export product). Meanwhile the fees for the electrical network infrastructure grow significantly without smarter network solutions, so smart solutions that avoid unnecessarily future costs are needed, a conclusion that the European trade association has come to: “Smart storage and control before cable!”

With already more than 200.000 electrical vehicles registered in Sweden, each about 10 kW on average, these have already the same peak power as 2 nuclear power plants.
Electric cars are fundamentally changing the energy system, and they are rather an asset than a burden. The advantage of electric cars is that they do not have to be fully charged all the time. The effect can be adapted to the needs of the electricity network, cushioning peaks through utilizing off times.

EMS (Energy Management System) is a service for energy-related data and smart control for hybrid inverters (photovoltaic systems with connected battery storage for example) and electric car chargers that can minimize power-related costs locally in the building and perform frequency regulation for Svenska Kraftnät, which generates revenue for the owner.

CheckWatt enters cooperation with Car chargers

CNets spin-off company CheckWatt is expanding its product portfolio to meet the growing popularity and needs of electrical vehicles (EVs). Sweden is ranking among the world’s top ten market for best-selling plug-ins since 2015.

In December 2020 a total of 217,704 plug-in vehicles have been registered, 148,889 plug-in hybrids, 62,870 all electric cars and 5,945 all electric vans have been registered in Sweden since 2011. As EVs are actively supported by the government with financial grants and charging at home is cheaper than petrol, diesel or public charging more home owners are looking for smart solutions. CheckWatt does not only want to offer homeowners a solution to charge their cars, but also to manage their electrical home installations, solar installations and to maximize savings reducing power-related costs. Solutions enable users to visualize charging together with other energy-related data. For starters CheckWatt initiated a collaboration with EpSpot and Zaptec, further collaborations are being negotiated.

EnergyInBalance News

EnergyInBalance has published this week a Newsletter with new releases and the latest news in the Energy sector. Based on an algorithm that takes into account the history of over 4000 solar installations that are represented by CNet’s spin-off company Checkwatt, a unique “fingerprint” for each plant is created. Based on this fingerprint derivations in the performance of each installation can be detected fast and without knowing local conditions such as slope, direction and local shading it can detect abnormal electricity production that is likely due to a fault in the plant.

The service offers owners the detection of real-time operational disruptions and notifications about even small deviations, minimising the effort for maintenance and shortening the time of production losses. The service will be launched in autumn and requires no additional equipment.
