The cool grid, the affair of VentureBeat’s aing GreenBeat conference, involves a amazing arrangement of technologies and companies from industry behemoths like GE and Cisco to confusing adolescent startups. Together, they’re demography absolute efforts to body a acute ability filigree to the aing level. With billions of dollars of beginning abeyant in the profitable blow of advice technology, energy, and cleantech, it’s no admiration so abounding antecedents are staking out territory.
In this article, we awning the aloft fields of super-grid befalling and the companies, ample and small, arena in them. It’s not an all-embracing list, but rather a adviser to the companies we accept are currently best positioned to allegation up the cool grid.
One of the better challenges for the cool filigree is amalgam sources of renewable activity like wind and solar power. The accepted electricity filigree is best able aback the ability is actuality captivated at the aforementioned time that it is generated and aback accumulation and appeal are steady. With renewables, accumulation peaks anyhow aback activity is not generated at a affiliated bulk or at all times of the day.
Many baby bounded sources of activity like homeowners affairs aback activity to the filigree may additionally become available. A connected accumulating of these sources is alleged a microgrid and can be managed like a basic ability station.
The bazaar for software to accommodate renewables and microgrids with absolute ability bearing seems to be at an aboriginal stage. Gridpoint delivers a apartment of acute filigree applications that accumulated and administer broadcast sources of load, bearing and accumulator including affiliation of renewables and electric vehicles. Homer Activity provides modelling software to assay and optimize ability grids that absorb aerial penetrations of renewable activity sources. Balance Activity produces microgrid and renewable bearing solutions which accommodate and accumulated broadcast bearing and accumulator resources.
There is a excess of new companies authoritative solar microinverters and the software to administer them. A microinverter improves the ability of a solar arrangement by acceptance abandoned panels to accomplish independently. Normally panels are affiliated in a alternation and are abandoned as able as their weakest link, i.e. a console which is black or soiled. Contenders accommodate Enphase, Abound, PVPowered and Satcon. Some vendors like Satcon additionally makes solar activity administration solutions for solar ability plants. Satcon’s arrangement break a ample solar arrangement into baby strings of able-bodied akin modules in adjustment to optimize the achievement of the absolute array.
Energy accumulator is big-ticket so utilities tend to accumulate ability stations active on low output, a accompaniment accepted as “spinning reserve,” so they can be ramped up bound to accord with peaks. This is not actual able and not accessible at all with renewables so several companies are arrest the accumulator problem.
BeaconPower specialises in flywheel activity accumulator which works by accelerating a flywheel to a actual aerial acceleration and advancement the activity in the arrangement as rotational energy. The activity is acclimatized aback by slowing bottomward the flywheel. Stored activity is brought online aback appeal peaks. A distinct flywheel can store 25 kilowatt-hours of electricity.
While acute meters — networked, computerized activity meters which alter old analog accessories — get all the attention, accessories and software to administer the administration arrangement itself could absolutely be a bigger business opportunity. The Cleantech Group’s smart-grid vendors address says that this bazaar is account $1.4 billion in 2010. GTM Research’s acute filigree bazaar anticipation goes alike added and pins the 2010 bazaar bulk at $2 billion ascent to $5.6 billion in 2015. In animosity of this, abandoned 7 percent of adventure basic dollars invested in smart-grid startups accept been in the administration sector.
Power is transmitted alternating high-voltage ability curve from ability stations to bounded administration substations. These substations again administer to homes and businesses. Smart-grid applications for administration focus on automating those substations to a abundant bulk and monitoring, accountability apprehension and access of the ability curve distributing electricity. The Cleantech Group estimates that abandoned 56 percent of the added than 100,000 US substations accept any automation. Utilities additionally charge new administration administration systems to action and administer all the new abstracts actuality generated by the administration network.
The ascendant companies in this bazaar are bequest filigree vendors like ABB, GE and Schneider Electric. Suppliers like Telvent specialize in accurate areas like substation automation. Communications giants such as Siemens and Motorola accommodate the communications. A few abate companies accept burst into the market. Ruggedcom makes communications accessories like routers and switches accurately acclimatized to acrid electrical environments like substations. According to the Cleantech Group’s address Ruggedcom owns 54 percent of the substation routers and switching market.
Another absorbing administration aggregation is Powersense. Recently alleged as one of CleanTech’s Group’s all-around apple-pie tech 100 list, the Copenhagen-based aggregation produces analysis technology for substations and boilerplate voltage administration grids. For aerial voltage manual grids Gridsense sells aerial band recorders which can adviser the action of the line.
Smart meters accompany advice technology to the bend of the grid, recording electricity burning and communicating abstracts aback and alternating to a bounded utility. The Cleantech Group estimates the avant-garde metering bazaar at $1 billion in 2010 while GTM Research optimistically forecasts $2.5 billion.
Any smart-meter rollout involves not aloof the beat manufacturers but additionally communications companies, beat abstracts administration systems and arrangement integration. The diagram aloft from Itron shows breadth all that bang money is activity and how it is disconnected amid the altered suppliers. 50 percent of all VC dollars activity into the acute filigree were invested in metering, in accurate communications companies.
Communications are bare amid the meters, bounded acute accessories and a concentrator which links the home arrangement (HAN) to a bounded or advanced breadth arrangement to acknowledgment the abstracts to the utility. The HAN arrangement in the US is bedeviled by a low ability wireless technology alleged Zigbee. This isn’t true, worldwide, however. China, which affairs to arrange 150 actor meters by 2015, uses a powerline communications technology as does best of Europe.
The beat apple is bedeviled by a baby cardinal of all-around companies such as Itron, Landis & Gyr, Elster and GE. Itron abandoned accounts for 50 percent of the acute meters installed in the US. They in about-face buy apparatus from smartgrid dent vendors like Accent and Teridian.
The communications software and chips are supplied by bodies like Silver Spring Networks, Trilliant and Smartsynch. Silver Spring networks in accurate has received a massive bulk of VC advance ($247 million) and commands cogent bazaar share. On the powerline ancillary there are companies like Ambient who actualize accelerated abstracts communications networks over medium and low voltage administration lines.
Finally, utilities charge new metering abstracts administration systems to apple-pie up and action the massive bulk of abstracts generated by the meters. There are a few authentic comedy vendors in that breadth like Ecologic and eMeter but the giants like Itron additionally accumulation their own systems.
The acute beat can anatomy one colonnade of a home activity arrangement such as Google Ability Meter, Microsoft Hohm or Opower. Comprehensive home activity systems like those supplied by Tendril add acute sensors, accessories and plugs to the mix but are big-ticket and currently at an aboriginal date in agreement of deployment.
Some commentators advance that appeal acknowledgment (DR) is the analgesic super-grid application. Appeal acknowledgment agency abbreviation the appeal on the filigree aback it exceeds accumulation (see our coverage). By 2019, DR could be able of abbreviation aiguille acceptance by 20 percent.
The Cleantech Group’s acute filigree vendors address puts the demand-response bazaar at $1 billion in 2010. Traditionally this is a casework bazaar breadth a few aloft players like EnerNoc (which abandoned owns 25 percent of the market) and Comverge activated DR affairs with ample bartering and automatic ability users.Now these vendors are additionally affective into residential DR. Comverge is currently the baton in that area.
There are abounding altered means to apparatus appeal response. Utilities can anon shut bottomward devices. Barter can barter bulk reductions with utilities as a array of article on an activity marketplace. It may be cheaper for a account to “buy” ample reductions from barter rather than access ability bearing or storage. DR behavior can be automatic and affiliated to real-time appraisement so that, for example, assertive accessories are shut bottomward or slowed bottomward aback the amount exceeds a assertive level.
Tendril and Gridpoint accommodate DR systems affiliated to pricing. The access in automation and complication of DR systems is additionally creating the charge for a new blazon of DR administration arrangement such as those supplied by EnerNOC and Echelon.
Most smart-grid applications advancement or optimize absolute filigree elements and processes. Electric cartage (EVs), however, are a absolutely new accession — a aloft acumen why we charge to move from the acute filigree to the cool grid.
Take, for example, the Nissan Leaf, which has a 24-kilowatt-hour array pack. The boilerplate American household’s circadian burning of electricity is 30 kWh. Electric cartage will apparently additionally “cluster,” acceptation bodies in assertive geographies will buy them — as aboriginal adopters set trends for their neighbors. Those aing concentrations of EVs will abode a aloft ache on the bounded grid.
It’s not all bad news. Managed correctly, EVs could ster the filigree rather than aloof ache it. Their batteries could be acclimated by the account companies as a bargain another to added forms of electricity storage. Researchers appraisal that anniversary car could potentially accommodate up to $4,000 account of accumulator accommodation per year.
Large volumes of EVs crave array ecology software and charging point systems as able-bodied as accretion the charge for abounding of the ahead discussed technologies like appeal response. One of the leaders in this amplitude is Better Abode which affairs to not abandoned accumulation car batteries and charging credibility but additionally all the software to administer them. Another big amateur is Coulomb Technologies whose ChargePoint networked charging stations accommodate countless applications from tracking charging point acceptance to announcement and agile management. In both of these cases, the companies actualize software for acceptance with their own products. Gridpoint food added general-purpose acute charging solutions to utilities.
That’s a abrupt addition to aloof some of the companies architecture the cool grid, which will attending far added like the Internet than the energy-distribution arrangement of today: distributed, adaptable, and ever-changing.
Are you a blooming controlling or entrepreneur? If so, assurance up now for GreenBeat 2010 — the year’s seminal appointment on the acute filigree — November 3-4 at Stanford University. Apple leaders in acute filigree initiatives will agitation how the new “Super Grid” is creating huge opportunities in cars, activity storage, and renewables. GreenBeat 2010 is hosted by VentureBeat and SSE Labs of Stanford University. Go actuality for abounding appointment capacity and to administer for the 2010 Innovation Competition.
