Sandra Trittin

The through-line

Across her posts, Sandra Trittin keeps returning to one claim: the energy transition is not blocked by missing technology but by missing structures to make that technology work together and pay for itself. She states it directly about flexibility - "It is not a technology problem. Heat pumps, batteries, EVs, solar: all exist, market-ready... What is missing is the business model that turns them into reliable infrastructure" [5]. This runs from her account of building the first European residential VPP, where the business case first looked strong and then collapsed as ancillary-service prices fell "from CHF 190 per MW/h to CHF 9" [7], to her repeated calls for standardization "behind hidden APIs, specifically developed protocols" that never reach mass acceptance [2]. Over time the focus has widened from a narrow monetization problem (ancillary services) toward a broader systemic one: aligning value chains, regulation, data trust and consumer understanding all at once.

On making complexity understandable

Trittin repeatedly returns to the gap between technical reality and what a customer can actually grasp. She contrasts an easy-to-explain solar eclipse price spike with a harder one: "today, the sun is shining but prices are still expected to rise?... why do jelly fish in France impact my power price in Germany? Explaining this to e.g. my oncle takes a bit of time" [1]. She sees the task as "moving the complexity of the second case into easy to understand examples as the first" [1]. The same gap shows up in a concrete tariff example: a good industry idea to shift load with lower midday network fees collides with the customer's actual questions - "Sommerniederarbeitspreis: was ist das und wie jetzt? Um welche Zeit?" and "warum Netzgebühren und nicht Strom" [8]. Her verdict: "Die Idee ist gut. Ein erster Schritt. Der Gap noch gross" [8].

On standardization and interoperability

Watching LEGO bricks fit together regardless of age, she wishes for the same in energy: "We have managed to build our bricks, with solar, storage etc. but unfortunately they do not always fit- hidden behind individual APIs, specifically developed protocols or standardization initiatives which are not reaching mass acceptance" [2]. She names the underlying conditions as alignment across the whole value chain and shared distribution of "effort, risk and value" [2]. This connects to her view on proving impact in flexibility: "Trust follows granularity of data" and standardization is needed "for interconnection and data" [10].

On business models and value stacking

Her account of entering the flexibility market shows the arc from optimism to pressure: "When I started in flexibility, provision of ancillary services were a lucrative business," which justified building "the first European Residential VPP based on heating systems for FCR services" [7]. The payoff was mixed - "happiness on one side to have passed the technical proof, but disappointment on the other: 9 CHF/MW/h the only value left in the market and the business model at risk" [7]. Her conclusion is that "value stacking for flexibility is non negotiable" [7], echoed in her broader claim that efficiency measures alone are insufficient and "flexibility is crucial" for using assets that already exist "without building a single new one" [5]. She extends this to hardware manufacturers, framing them at a crossroads as "a bridge or a tollgate between the customer and the power system" now that "software layers for monitoring, control and aggregation get into focus and keep manufacturers up at night" [6].

On collaboration and systemic alignment

Trittin frames distributed energy resources through a political analogy, comparing Swiss federalism's "735 Live Betrieb, ohne einen Systemausfall" to distributed power plants where "jedes der teilnehmenden Geräte optimiert sich lokal und unterstützt gleichzeitig... die Belastbarkeit und Sicherheit der Stromversorgung" [4]. She calls this combination of "lokaler Eigennutzen kombiniert mit übergreifender, systemdienlicher Optimierung" not simple but forward-looking [4]. The same emphasis on shared effort appears in her reflection on a swisscleantech event: "wir schaffen es nicht alleine, die notwendige Power und Geschwindigkeit erreichen wir nur gemeinsam" [14], and in her description of climate cooperation as resting on openness, common ground and clear value definition for "consumers" and other parties [13]. She also uses resource scarcity - shrinking Lake Zürich, a shut-down nuclear plant on an overheated river - to argue for paying closer attention to "input sources" underlying electricity production [3].

From the stage

In the Solar&StorageXtra interview she lays out operational obstacles to scaling virtual power plants that her written posts don't detail: regulatory complexity around market access for distributed energy resources, the high upfront financing cost for consumers buying heat pumps and storage systems, and a scarcity of skilled installers needed for deployment [15]. She frames Beebop's mission there as aggregating "thousands of individual assets into virtual power plants that can be traded in energy markets like traditional power stations" [15], stating the commercial goal more plainly than in her LinkedIn commentary.

Takeaways

• When explaining price spikes or tariff changes to customers, translate the technical cause into an intuitive comparison rather than the mechanism itself [1][8].
• Treat interoperability as a first-order problem: fragmented APIs and protocols are blocking flexibility from reaching mass adoption the way LEGO bricks reached universal compatibility [2].
• Expect ancillary-service revenue for flexibility assets to compress over time; design business models around stacked value streams rather than a single market [7].
• Efficiency technologies (heat pumps, batteries, EVs, solar) are already market-ready; the constraint is the business model and consumer product wrapped around them, not new hardware [5].
• Hardware manufacturers need to decide whether to become a "bridge" enabling software-driven flexibility value or a "tollgate" resisting it, which requires reworking sales, distribution and installation [6].
• Before scaling any distributed energy resource program, budget explicitly for regulatory market-access complexity, consumer financing barriers, and installer capacity shortages [15].
