On your side
Sakha Energy has no products to sell. I act on your behalf, so you can deal with retailers, installers and suppliers as an informed customer.

About
Hi, I'm PK Saxena
I founded Sakha Energy to give businesses and communities the kind of clear, data‑driven energy advice that is usually reserved for large organisations.
Motivation
Why I started Sakha Energy
My path to energy efficiency is rooted in habits we were taught as kids: switch things off when you leave the room, and don't waste.
Years later, after joining a Virtual Energy Network, I found myself helping others navigate a promising but complex energy product. Along the way I built up expertise in energy analysis, and in matching the solution to each person's context. Those are skills I borrowed from my aviation career, and they are now the heart of my work in energy.
Energy decisions are too often made on the strength of a sales pitch. I wanted to offer the other thing: someone on your side of the table, working from your own data, with nothing to sell.
The journey
How I got here
Aviation engineering, teaching and community energy look like three different careers. They turn out to share one habit: making sense of data so that people can act on it.
-
Growing up
Habits that stuck
Switching things off when nobody is in the room, and avoiding waste. Simple habits, taught early, that I have never lost.

2004 to 2008
Aerospace engineering
Bachelor of Engineering (Aerospace) at RMIT University.

Since 2011
Aviation engineering
I worked for a number of years analysing aircraft maintenance data and turning it into recommendations and action plans, in senior engineering roles across small regional airlines, special operations operators, national carriers and aircraft manufacturers (OEMs).
Aircraft reliability work leaves you with a discipline: decisions have consequences, so the reasoning has to hold up.

2022 to 2023
Teaching in regional South Australia, and going electric on the road
While living in rural South Australia and teaching Science and Mathematics at a regional school, we decided to buy an electric vehicle. This was back when public charging nearby was very sparse, nearly absent.
We navigated that, and saved significant money, because long commutes are part of regional life.

From 2024
Back in Adelaide: electrifying the house
We moved into a house with a large north‑facing roof and no solar. I commissioned a 19.4 kW solar system, including a three‑phase upgrade and a thorough check and overhaul of the house's electrics, with 22 kW car charging. To make better use of the surplus power, I converted the water heating to electric.
The result is very small electricity bills and overall energy costs that are insignificant, despite busy travelling needs and heating and cooling a large four‑bedroom double‑brick house with several living areas and an older ducted air conditioner. Careful planning, leading to real savings.
-
From 2024
Community energy
I joined a Virtual Energy Network, which made advantageous peer‑to‑peer solar sharing possible, and soon found myself helping others make sense of it.
Today I am a member of the WinZero VEN Steering Committee, manage the Virtual Energy Networkers group and volunteer as a moderator of My Efficient Electric Home (MEEH).

How I work
What you can expect from me
Your own data
Recommendations come from your interval data, bills and site data, with the figures behind them in plain view.
Plain English
Reports you can read, keep and share. If something isn't clear, that is my job to fix, not yours.
Fixed properly
A philosophy borrowed from aircraft reliability work: replace an inefficient process with an efficient one, rather than supplement it with band‑aids. You get a clear, reasoned plan that holds up to scrutiny.
How we work
Smart tools, human judgement
We use AI, responsibly, to deliver value‑for‑money analysis that helps clients keep more of their hard‑earned money in their pockets. Best‑practice tools let us work faster and more thoroughly, so you get best‑in‑class analysis at an affordable cost.
- Human oversight of every analysis
- Your data kept strictly contained and private
- Recommendations interpreted and explained by a person, not a chatbot
- Best‑practice tools, priced for small business

Energy consulting: solution provider to QuantumNRG
PK Saxena has worked as a solution provider to QuantumNRG: developing analysis, building customised data‑based solutions and processes, and providing public liaison, webinar hosting and stakeholder liaison. The examples below were delivered in partnership with, and as a service provider to, QuantumNRG.
- Deakin University research study. Energy data analysis and participant support for Deakin's Virtual Energy Network study. The findings were presented to the community in the webinar below.
- 18‑site agricultural portfolio. Plan structures reviewed and solar‑sharing arrangements confirmed across the portfolio, site by site.
- Multi‑site winery and farm. Five sites modelled across retailers to show where solar sharing between sites pays and where it doesn't.
- Plan withdrawn by the retailer. When a client's plan was discontinued, we found the lowest‑cost path forward and kept the increase to a minimum.
- Billing errors caught. Invoice reconciliation showed peak‑rate windows were applied differently from the plan documents, giving the client grounds to challenge.
- Small businesses and cafés. Tariff reviews and solar and battery sizing that turn a confusing bill into a clear, costed next step.

Giving back
Senior Science and Mathematics teaching at a rural South Australian school and in Adelaide: coaching, mentoring and giving back to the community.
It's also why our reports explain things plainly, not just get the numbers right.
The name
Sakha means friend
Sakha (सखा) means friend or companion. That is how I work: alongside you, with the numbers in plain view.

Outside work
A tinkerer at heart
I keep busy working out new ways to automate the lights around the house (occasionally to the chagrin of my partner, who only complains about one particular light!) or setting up the air conditioning to respond to wholesale price signals.
Home automation is a useful hobby, and one I am happy to help a client with.
