Tesla held a digital energy plant (VPP) workshop for the Electrical Reliability Council of Texas (ERCOT) on Could 31. Gail Alfar, the author at What’s Up Tesla?, attended and shared her ideas. Additionally in Could, Tesla made a request for Powerwall homeowners in Texas to choose into the Tesla ERCOT Demonstration to indicate the utility precisely how nicely VPPs work.
Gail famous that the workshop was hosted by ERCOT and led by leaders at Tesla Vitality, together with Arushi Sharma Frank, US Vitality Markets Coverage Lead at Tesla. Tesla designed an illustration take a look at and 64 Tesla Powerwall battery homeowners participated. They may present vitality as an combination and the demonstration confirmed spectacular efficiency, Gail famous. The demo proved that there have been no technical blocks stopping the homeowners from offering energy to the Texas grid.
The very same precision dispatch we will get from house batteries, if we will get by way of the technical acrobatics famous at present on the #ercot #VPP workshop. It is price repeating- nothing in TX at present lets properties behave like a hive thoughts and ship clear MWs 24x 7 to the grid.

Gail not solely attended the workshop, however she was additionally invited to talk and share her ideas from the attitude of a registered nurse. She talked about that many households have been deeply affected by the extreme energy outage in February 2021 and that since Tesla has already demonstrated that it will possibly present dependable energy by way of VPPs, there isn’t a motive for any delay in permitting full participation as quickly as doable.
“As a healthcare supplier, I advocate for individuals in want. Having energy is necessary to individuals’s well being.”
When you didn’t attend the workshop, you possibly can nonetheless view Tesla’s presentation right here. Tesla defined the coverage motivators in addition to how prospects supplied providers and solved issues for the grid.
“Texas has hundreds of Megawatts of belongings on the distribution system, trending the acceleration in distributed vitality sources (DERs) (behind-the-meter technology and storage)
“FERC’s ‘Order 2222’ doesn’t apply in Texas — however Texas regulators acknowledge the necessity to mobilize this capability.”
The core downside, Tesla identified, is that Texas wants all obtainable, reasonably priced, dispatchable electrical capability/sources mobilized to handle grid reliability challenges. Distributed vitality sources are essential right here. Nevertheless, these are thought-about unrealized dispatchable belongings to ERCOT.
The short-term resolution is to make minor modifications to an already current and unutilized ERCOT market design idea that was developed 9 years in the past. Tesla famous that this might instantly unlock grid reliability providers from small distributed vitality sources dispatched as an aggregation.
Tesla famous that this was its direct effort with ERCOT to make extra grid providers obtainable and that the aggregation of round 60 prospects was in a single ERCOT load zone. This was made doable by Tesla’s aggregation-building options in addition to its ancillary providers capabilities utilized in different markets. It was additionally made doable by collaboration with ERCOT employees to set parameters for VPP efficiency particular to ERCOT operations and dispatch guidelines in addition to Tesla’s expertise with delivering grid providers in different markets.
The outcomes confirmed that there have been zero technical blockers.
Tesla plans to file the outcomes of the VPP demo with the Texas Public Utility Fee (PUC). In April, Will McAdams, Texas’ PUC commissioner, said in a memo:
“Our workplace has taken up what an important points, issues, and coverage parameters have been to be thought-about on the subject of distributed technology, on distributed vitality sources. I name it the holy grail challenge. If we will crack the code on that then the grid has limitless potential, by way of segmentation, by way of resiliency functionality, by way of useful resource adequacy. All the opposite grids are tackling this as nicely, FERC is keenly eager about it.”
Tesla is prepared and capable of assist Texas crack that code. Tesla supplied a long-term resolution in addition to consideration for these approaches.
Tesla famous that grid operators have been working in the direction of mobilizing distributed vitality useful resource (DER) capability for a couple of years and have a mannequin for sizing the congestion zones, or in different phrases, limiting aggregations at a congested transmission node. Nevertheless, Texas hasn’t but labored on an answer for giant DER aggregations. Texas might want to discover a inventive resolution that aligns with nodal dispatch if it desires to develop this market. Tesla emphasised that large-scale DER penetration will enable ERCOT to shift demand from interval to interval much like how they shift provide at present.
I lived in Texas earlier than, and it will possibly get actually scorching there — even hotter than in South Louisiana. Some components of Texas have related humidity ranges. Texas and its residents must have a dependable grid so as to survive this warmth and humidity. I believe Tesla will show to be a terrific ally for the state, ERCOT, utility corporations, and the individuals, particularly throughout instances of intense warmth or different excessive climate occasions.
I requested Gail if she had anything she want to add and she or he spoke of her experiences as a nurse and witnessing how persons are affected by the lack of energy when it occurs.
“As a Texas resident and registered nurse within the state, I straight see people who find themselves affected once they lose energy. Whether or not it’s excessive warmth or extreme chilly, individuals’s lives and well being are in danger. Tesla is providing a utility within the type of a digital energy plant, or VPP, to ERCOT.
“Tesla already examined this digital energy plant utilizing 62 prospects and the system labored flawlessly, responding shortly to energy wants. This short-term resolution would be the begin of one thing fantastic for Texans. I look ahead to the Texas grid getting stronger when ERCOT permits Tesla to take part.”
She’s appropriate to say that lives are in danger when the facility goes out — particularly if it’s out for lengthy intervals of time. Throughout Hurricane Ida, the within temperature of my condo acquired to 140 levels and my two cats virtually died. I used to be very grateful and relieved when the facility lastly got here again.
We regularly take electrical energy with no consideration, and I believe what Tesla is making an attempt to do in Texas is necessary and will set an instance for different states, together with Louisiana.
